Re: Ajax Post Value on CF Side
Once you convert it into a CF structure using deserializeJSON, you can then
use cfdump to see how CF interprets it.

Re: Ajax Post Value on CF Side
With JQuery:
var post_data = $('#myform').serializeArray();
$.post('/mycfpage',post_data,function(data){
//do stuff with JSON data here
var name = data.name;
var value = data.value;
//then manipulate the DOM from there
},'json');

Re: Ajax Post Value on CF Side
Looks like a basic JSON value. Just parse it and you should have it put
into a variable.
or am I not understanding the question? I have yet to have my morning

RE: Ajax Post Value on CF Side
Solved. The problem was I was overcomplicating this and treating it like
JSON just like everyone else has been advising.
With an AJAX post, the string: Object {name: rid, value: 1}
Appears to Coldfusion as form values. The values #form.name# and
#form.value# give me rid and 1.
Too simple, so it confused me.

You can very easily convert it to a structure using the deserializeJSON
function in CF. Here is a link with some examples of working with JSON in
ColdFusion. http://www.learncfinaweek.com/week1/JSON/

Re: Ajax inserts / updates and CF
You don't necessarily have to turn it off. Just select dockable.cfm - that I believe allows you to have debugging on while using Ajax. That said, I've found it much better simply to use the firebug and web tools plugins in either FF or Chrome to debug Ajax requests. This is a great move and highly recommended for the reasons you mention, but also if you plan to go mobile. Just a tip for you...make sure you turn CF debugging OFF when testing your jquery ajax calls because if you leave it on, it may appear that your ajax is not working at all with no js errors. Also, I would recommend you use firefox as a browser and firebug to debug your jquery code. Hope this helps. Hi Folks, We're getting ready to implement some ajax code in our application to enable queries (esp inserts and updates) to run without having to do a full page refresh (the main goal being to just improve page load performance). There's obviously a lot of info out there on this topic and I'm interested in getting a little feedback about what might be best or most appropriate. For instance, are there any recommended examples / tutorials for doing this with CF? Would this sort of thing likely use jquery or just straight custom javascript? Many thanks in advance.

It is simply the name of a technique used in JavaScript to communicate with

not, the page is reloading and showing an overlay or something of the page.
If you go to http://www.makeaherodonations.com/themovement/ you'll see
what I am talking about. It's weird and I have been trying to figure this

$(document).ready(function(){

$.ajax({

data: orgname=+ usr,
success: function(msg){
$(#status).ajaxComplete(function(event, request, settings){
if(msg == 'OK')
{
$(#orgname).removeClass('object_error'); // if necessary
$(#orgname).addClass(object_ok);
$(this).html(' img align=absmiddle src=images/accepted.png / ');

I think that I'll have to head to the bookstore tomorrow and get me an
AJAX book. It seems pretty cool and something that I can use in the future.

As to your error, it is very obvious if you use the Chrome Dev Tools. I

I opened it up in Chrome, went to the Network panel, filtered on XHR. I
then entered 88 in the first form field.
I then saw a big ole graphic load. Why? It's obvious if you look at the

Re: AJAX Issue
Thanks Ray, I'll look into this for sure. And yeah, I am wrapping all the pages
in a header, footer and nab in the application.cfc. I'll switch it to an
include in the page instead. I've been out of web development for about 4 years
and have obviously fallen behind the knowledge curve. Thanks for the input I'll
work on this stuff tomorrow.

Re: ajax tutorials for form objects
+1 to Rick's +1 to Michael's suggestion. One of the great things about CF is the cfc's can automatically return arrays in JSON format that jQuery can consume. Like so: cffunction name=default returntype=Array returnformat=JSON I can tell you first hand that formatting JSON by hand from a data structure like a query can be a total PITA. So in that respect, returnformat=JSON is a Godsend for AJAX development. As far as Ajax tutes go, the documentation on the jQuery site for it's AJAX features is a great place to start http://api.jquery.com/category/ajax/ Also, the docs on CFSelect and cfinput that use the bind attribute is also a great place to start. http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=Tags_r-s_14.html CF takes a LOT of the grunt work out of working with AJAXish functionality.

The name and action are just there as example. What I'm asking is did you include *enctype=multipart/form-data in your cfform tag?

RE: Ajax file upload.
I'm more interested why it has to be cfform? Are you using the validation for cfform? You know that once your form is finalized, you can just download the JS that cfform outputs and ditch cfform for production? andy -Original Message- From: Steve Sequenzia [mailto:c...@thinksys.com] Sent: Monday, September 06, 2010 12:12 PM To: cf-talk Subject: Ajax file upload.

Re: Ajax, Json, and two clueless programmers
houseDetails = {address : 1970 ST CHESTER AURORA, 80010, price :
45000,listingNum : 833553, office : 303-487-0777 };
The returned info (price, for example) displays great with ID numbers
in a table as such: td id=price/td or like this p
id=price/p... but how the heck do I use it in a URL and (most
importantly) pass other variables with it, for example: a
href=?from=doitprice=PRICEVARIABLEHERE and have that link info
change without refresh right along with the rest of the page?
Using javascript you can access the json as a structure; houseDetails.price
returns 45000.
So basically once the dataset is returned you can use it to build your url
string.It really helps to use a framework or library that is meant to work with
json and ajax. Try prototype or jquery.
I can write the following:
document.createElement(a).href=index.cfm?price=+houseDetails.price;
You can also access elements by their id or relative position to other easily
accessed elements in jQuery or Prototype
So really if your dev guy is a good client side developer, you should handle
all of the cfc methods for him and have him do all of the javascript and client
side development. Or are you trying to learn how to write javascript?

Re: Ajax, Json, and two clueless programmers
first I would use jquery to make it easier but if neither of you know it the
first hurdle you will face is multiple clicks so you should put a div and class
around each link and then use jquery's live property which will make this
work right or else you'll be scratchin your head trying to get it.
then in the same function use jquery ajax function to grab info.
Also cfm returns json IN ALL CAPS, so propertyID becomes PROPERTYID in the
returned json.
$(function() {
$('td.propertyInfo').live('click',
var PropertyID = this.id;
//the line below is used with a regex to help filter data faster by
adding a

Just to clarify that CF ONLY returns JSON in all caps if you use dot

Dot notation
VARIABLES.myStruct.myKey - VARIABLES.MYSTRUCT.MYKEY
Bracket notation
VARIABLES['myStruct']['myKey'] - VARIABLES.myStruct.myKey

Re: AJAX Question
The way you do that depends on which Ajax library you are using. You insert data into the database the way you normally do using ColdFusion. The JavaScript that you use pulls data from the form fields, sends it to the server using any number of methods, then ColdFusion takes it from there and send back a response to the browser when it is done. Which JavaScript framework were you going to use, if any? Which version of CF are you using? Have you tried searching for examples on the Web yet? -Mike Chabot On Fri, Jan 22, 2010 at 9:48 AM, Matthew Allen a.matthe...@yahoo.com wrote: Can anyone please give me pointers or real life example of how to insert simple form field values into a database using AJAX.

RE: AJAX Question
Bear in mind that you do not insert values into a database with AJAX. AJAX
is merely way to pass said values to the processing page of your choice
without page refresh.
So assuming you know how to do a database insert with ColdFusion, you'd just
need to know how to pass the values from your client code to your ColdFusion
page.
jQuery makes this very simple:
$.get(http://www.yoursite.com/path/to/coldfusion/file.cfm;, {
// here's the key value pairs you want to pass in your request
key1: 'value one',
key2: 'value two',
key3: 'value three'
},function(data){
// if your processing page will be passing data BACK to your client
page
// then you'd do something with that data here.
});

RE: AJAX Question
One thing I forgot to mention. If you use the below method, then you'd
reference the values on the ColdFusion page in the URL scope.
URL.key1
URL.key2
Etc.
If you need a POST then you'd just change the var references to the FORM
scope, and change $.get to $.post

RE: AJAX Question
Matt here's a quick one using JQuery:
First off, you need to load the JQuery libraries in the head of the page.
script type=text/javascript
$(document).ready(function() {
$(#button name).live(click, function(){
$.ajax({
type:post,
url:url of processing page,
data:$(#form name).serialize(),
cache:false,
success:
function(){$(#receiving div).load(page to load on sucess)},
error: function(){
error functionality here;
}
});
});
)}
/script
From the top,
$(document).ready(function() {
This ensures that everything inside is as soon as the DOM is loaded, while
not as important here, if you're using JQuery for layout manipulation it's
critical, so make a habit of wrapping all JQuery code in it.
$(#button name).live(click, function(){
This script is triggered off of a button, make sure the button tag has an
id, this is what you'll trigger on.
url:url of processing page,
this is url of whatever actions you're going to call, hijacks the action
attribute of the form tag
success: function(){$(#receiving div).load(page to load on sucess)},
The page that you want to load after processing, and the div that it should
be placed in
error: function(){error functionality here;}
error functionality, error pages etc.
This is quick and dirty, there's an entire form plugin for JQuery that may
be better suited to what you need.
To debug any AJAX stuff, if you haven't already downloaded Firefox, do it
and get the firebug plugin, along with the JQuery plugins that are
available. The NET tab in firebug will show you all of the behind the scenes
stuff going on.
Hope this helps

RE: AJAX Question
It's mostly because I don't know of anyone actually using CF8's built in implementation. It's highly unlikely that anyone is going to be building a single AJAX call in a vacuum.

RE: AJAX Question
Better to stay consistent and use jQuery for everything rather than drop into a different implementation and syntax. From the sound of his question I'd bet he's not using any Ajax implementation and syntax right now. I don't know of anyone actually using CF8's built in implementation That's too bad. We use it, and we use it everywhere we do Ajax. We still use jQuery for pretty much all our other DOM manipulation and stuff but we simply can't beat the ajax proxy stuff when it comes to talking back to the server. It's simple, it does everything we need (like easy error-handling), and it works well. It's highly unlikely that anyone is going to be building a single AJAX call in a vacuum. I would agree, but the usage of any other JS framework (like jQuery) doesn't automatically preclude the possibility of me mixing and matching the best and easiest of all worlds. The OP is obviously getting his feet wet in Ajax right now. I'm sure he'll drink the jQuery koolaid like most of us in due time. In the mean time, he deserves to at least know the viable options that he already purchased along with his CF license. :) ~Brad Original Message Subject: RE: AJAX Question From: Andy Matthews li...@commadelimited.com Date: Fri, January 22, 2010 12:13 pm To: cf-talk cf-talk@houseoffusion.com It's mostly because I don't know of anyone actually using CF8's built in implementation.

Re: Ajax Query
Looks like everything is using Ext objects. Try building a function that grabs
each set value and places it in a corresponding hidden input on your page.You
need to store this collection somehow either in DOM or in form elements.
Easiest way to see your results is by using form elements that are hidden to
the user. I'm not sure how to grab the selected values but I'm sure Ext has
something built into the API for each object.
A universal function would look something like this:
//using jquery
function save(sourcevalue, elementIdToSaveTo){
$(#+elementIdToSaveTo).val(sourcevalue);
}
//standard js notation
function save(sourcevalue, elementIdToSaveTo){
document.getElementById(elementIdToSaveTo).value = sourcevalue;
}
You would run this for every item that you want to store.
I'm not sure if this helps. Without seeing what your client side looks like and
being able to inspect the elements, it is a little tough to figure out a viable
solution.

Re: Ajax Query
I know this is not the place to post such queries, but I am very stressed out now and can not find solution to my problem. Maybe someone hase had similar experience while using ExtJS with ColdFusion. My scenario is simple. Upon clicking a menu item on my homepage, a window opens. After filling out sertain textfields, when these fields loose focus, another modal window is opened having a grid. Now I want to the user to select one of the values listed in the grid and then press 'Done' button. Once this 'done' button is hit, I want the child window to close and the selected record in the grid of childWindow must be passed to the initial parent window. How can this be achieved? Regards, Arsalan Window is pretty loosely described. Is it a browser window or a DIV? There would be different solutions for either situation. Modal window sounds like a div. If so, you use javascript to get the value of each element based on the id. Instead of using grid, can't you use something else that would be easier to get values from? Even an 'li' would suffice. Then use placeholders in your parent window, like hidden inputs to store the passed values. ~| Want to reach the ColdFusion community with something they want?

You can't use QueryParams for the order by (or dir) parts of SQL. It can only be used for values in WHERE clauses.

RE: AJAX CFGRID will not sort by column?
To be a bit more exact, you can only use cfqueryparam in a place where a regular SQL parameter could be used. For MSSQL server, this could be in the WHERE clause, the SELECT clause, JOINs, etc. However, SQL Server doesn't allow you to do this: DECLARE @orderBy varchar(50) SET @orderBy = 'name' SELECT name FROM person ORDER BY @orderBy Therefore, you cannot parametrize that portion of a select with a cfqueryparam either. The important thing to come away from this with is that you still need to prevent SQL Inject attacks! Blindly outputting the values sent in from an Ajax call could be hazardous to ones server. One method is to check the contents of ARGUMENTS.gridsortcolumn and ARGUMENTS.gridsortdir against a list of known good values. cfif listfindnocase(firstName,lastName,age,argumentsgridsortcolumn) ORDER BY #argumentsgridsortcolumn# cfif arguments.gridsortdir eq DESCDESC/cfif /cfif ~Brad Original Message Subject: Re: AJAX CFGRID will not sort by column?

Re: ajax cfc not working for Access DB -- odd stuff
If the cfc is being hit, and with the right data, you can absolutely rule
out the cfajaxproxy tag. Can we clarify that the data being returned from
the method is the problem? Try posting a form directly to the cfc method,
e.g.
form method=post action=pathtocfc.cfc?method=fubar!--- I think that's
right, have never done it ---
!--- your fields, etc ---
/form
From there, debugging should be more straight forward.

Don't ever do that.
But seriously. First step of debugging ajax: install Firebug for Firefox
if
you haven't already. Next, enable all the firebug console options for your
page and while viewing the console tab you should see your http post
request
made by your proxy js object (when you fire that event). You will then be
able to examine the the data sent to your cfc and also the response.
If there is no http request sent then the problem may well be with the
cfajaxproxy code - if a request *is* sent, then we can safely move on from
the client side code.
With any luck, examining the http response will tell you exactly what's
going wrong and will be a cf / railo error page.
HTH
Dominic
Very ODD.
The line of cfreturn #result# in the cfc should have been
cfreturn true since we don't need data back from the cfc.
and was previously cfreturn true. I've enabled the feature in FF.
case A, cfreturn true
ajax http post succeeds, RESPONSE: the {data} instead of TRUE ?
case B, in the cfc, cfset result=fielda, #fa#; fieldb, #fb#;
memofield,#mf#
cfreturn #result#
(just for the heck of it),
ajax http post succeeds, RESPONSE: just the #mf# instead of fielda, #fa#;
fieldb, #fb#; memofield,#mf# ?
FYI, the computer is totally offline and wireless device driver was turned
off as well.

I have firebug lite set up for the IE7, but it didn't show http call etc. from cfajaxproxy as in FF/FB... more thoughts? thanks. ~| Want to reach the ColdFusion community with something they want?

Very ODD.
The line of cfreturn #result# in the cfc should have been
cfreturn true since we don't need data back from the cfc.
and was previously cfreturn true. I've enabled the feature in FF.
case A, cfreturn true
ajax http post succeeds, RESPONSE: the {data} instead of TRUE ?
case B, in the cfc, cfset result=fielda, #fa#; fieldb, #fb#; memofield,#mf#
cfreturn #result#
(just for the heck of it),
ajax http post succeeds, RESPONSE: just the #mf# instead of fielda, #fa#;
fieldb, #fb#; memofield,#mf# ?
FYI, the computer is totally offline and wireless device driver was turned off
as well.

Re: AJAX
widgets are the autosuggest combobox, the html data grid, border layouts, modal windows, etc., typically loaded by a remote source via Ajax. So, some of what you mention (the search field) falls under that category, while some of the other stuff is just pure Ajax, for which either JQuery or Ext Core are both well suited.

Re: AJAX Solution to Read database and load new Image
There are just a ton of ways to do exactly this, its a bit of general
question.
It sounds like maybe you are looking for some example code? Are you using
any Javascript frameworks?
The general flow to the update is going to be this:
1. A function is called via a page onload or something.
2. This function creates an XMLHTTP request and sets the callback
function that will get passed the data returned from the http request.
3. The call back function receives this data, and does the javascript to
set the image attributes appropriately, it then does a setTimeout back to
the original function. (goto step 1)
Creating the functionality involves the server side programming. When I was
first learning Javascript and using the XMLHTTP request i was using a
serverside script that returned raw html or delimited strings that was
parsed as appropriate by the callback function. In this case the server side
script could simply return the relative path to the image which the callback
function could then document.getElementById('imageid').src = returnedText.
If you have time and are actually trying to learn JS, a better approach
would be to have the server side script generate a JSON object which would
make it easier to add more than one value to the data it returned to the
clientside JS, say the next step in improving this would be to return a
string that would serve as a caption below the image. JSON is a cake to
parse client side and is lighter weight that XML.
I have a ghetto xmlhttprequest object i use but I'd recommend you go get
jQuery and read 3 or 4 pages of documentation on their ajax object. It would
allow you very simply return the full img tag from the server side script,
and then periodically populate some arbitray div with the results.

Is there a simple AJAX solution that can accomplish this for me?

However, looking at the source code I see that the Ajax request is looking for /myCFC.cfc instead of /projects/myCFC.cfc.

Re: ajax controls break after time interval, return 302
Are you this is not due to a login timing out? The 302 http error is a redirect code which makes sense if your login expired and your code is then trying to redirect the ajax call to the login page. Can you determine which page the redirect is attempting to load? This could still be a session timing out depending on how your application re-loads a users session. Do you have you application detecting users via a cookie and auto re-logging them in and re-building the session? If so does the page the ajax call is referencing have the same ability to auto re-login? Usually this is what has happened when I've seen this error in the past.

Re: ajax controls break after time interval, return 302
Pardon the reply to my own message, but Wil, you were right on...CAS had expired my authentication, and when an ajax call stumbled into this, the redirect wasn't handled properly (not sure it can be in the middle of say, ColdFusion.nagivate(), other than triggering the onError() callback). For now, the CAS timeout has been set to just longer than the session timeout; while I'm not sure this will completely prevent the error, it should make it vanishingly improbable. thanks, Phil Phil Stone wrote: Wil Genovese wrote: Are you this is not due to a login timing out?

If everyone wanted to talk about Ajax enough to expand the list, they'd be on the Ajax list. 'the list owner' has worked hard to make this list what it is and continues to work hard keeping off-topic traffic off of it for a reason. Why willingly open up the flood gates now just because you have some off topic questions that don't get answered somewhere else?

Unless you take a lot of care, they won't be search engine indexable (may or may not be an issue) or bookmarkable.

Re: ajax submit form
Hi Chad,
You'll hear some good advice about properly using Ajax-based
technologies and the advice I can give you is to look at progressive
enhancement. It's ensuring that your application works as expected
using traditional development methods and then gradually enhancing it to
leverage JavaScript, DHTML and Ajax. In your case, it appears that
you're halfway there since you already have a working search form. The
next step is to begin adding the JavaScript, DHTML and Ajax gradually
until you get the desired effect that you, all the while ensuring that
your page still functions when JS is not enabled.
I would urge you to look up the topic before wandering too far into
making substantial updates:

RE: ajax submit form
Guess I should have explained since the topic is shifting this direction.
I don't have to worry about whether their JS is turned on. It is for a
Intranet web site that I have control over what browsers and browser settings
are being used.
I just need to find the best functions in CF8 to accomplish my goal. So far it
looks like I have to brush up on my javascript to get CF8 to do what I want.
I will check out the link you sent.
So far I have the following, but I need to switch it to a form instead of a
hyperlink and somehow get the text input into the ColdFusion.navigate function.
I think I can do this with javascript.
html
head
!--- The Callback handler puts text in the window.cfm callback div. ---
script language=javascript
var mycallBack = function(){
document.getElementById(callback).innerHTML = brbrbThis is
printed by the callback handler./b;
}
!--- The error handler pops an alert with the error code and message. ---
var myerrorhandler = function(errorCode,errorMessage){
alert([In Error Handler] + \n\n + Error Code: + errorCode +
\n\n + Error Message: + errorMessage);
}
/script
/head
body
cfdiv id=w1
This is a cfwindow control.brbr
a href=javascript:ColdFusion.navigate('searchTest.cfm?query=White
Plates','w2',
mycallBack,myerrorhandler);Click/a to navigate Window 2/a
/cfdiv
cfdiv id=w2
This is a second cfwindow control.
