Re: [jQuery] Response converted to entities after file upload
A couple of things to try. First, run phpinfo() and look through the output for anything that could be filtering the output. Second, try using double quotes or echo or print() in place of die() and follow with exit. die() does not escape html (at least not on my servers) so I suspect that phpinfo() will show something that is filtering your output. 2010/2/17 Lay András laysoftjqu...@gmail.com: Hello!

You may want to remove the $header method. PHP should send the content-type text/html header by default.

Re: [jQuery] Is there have any JQuery plugin that can sort 1A,2A,3A,... 10A, 11A, 12A, 13A, 14A?
Hi, I'm not sure what DBMS you are using but most can sort many ways. You may want to read your DBMS manuals and look for a natural sort method. MySQL uses something like ORDER BY column_name NATURAL ASC or ORDER BY column_name NATURAL DESC. Somewhere on the net should be an old thread about sorting mixed numbers and alpha characters in MySQL. Try Googling the topic. If the DB can handle the sort for you, you'll save time and network traffic. Unless you really need to be able to sort this on the client side.

[jQuery] Replacing a portion of an href value
Hello, I have the following code which is part of a loop to add preview images to a filmstrip where each cell is made up pf a div. My filmstrip uses a tiny bw version of the image which is stored in the images/s/ folder. My preview images must come from the images/m/ folder. I have tried using replace() but have not been successful at it. Any help would be greatly appreciated. Code: $(body).append(div id='preview'img src='+ this.href +' alt='Image preview' /+ c +/div); Original href's are similar to: sitename.com/images/s/image_name.png I need the following replacement: sitename.com/images/m/image_name.jpg So I need to replace the sub-folders and the file extensions within the line above.

Re: [jQuery] Lists, Filtering and Searching, Oh My!
Would it not be better to provide a server side script such as php or asp to allow a paged, sorted, ajax call. Even if you put all this data in an access database or xml file the server side script can parse and return a small chuck of data reasonably fast. At 1800 records I'd opt for a database write a script to import/export to-from csv for that the list management can be done via xcell or similar app. On Tue, Jan 19, 2010 at 12:06 PM, John Arrowwood jarro...@gmail.com wrote: json is one approach. XML is another. CSV works, too. The format of the file should be what works best for the people that need to maintain it. Then, you need to find a good way of getting that data into the browser and in a format that is easy to work with. How often does this file change? Is this something that can be loaded at the beginning of the user session and then cached? Or do you need to update the user's view regularly? That is, do you need multiple ajax calls, or just load it all in on page load? If it were me, using Excel to manage the list, and exporting to CSV, then loading and parsing that is probably what I would do. Just make sure your CSV parsing code is bug-free. :) When you load and parse the CSV, just load each record into an object in an array. Piece of cake. Then you build your display based on the array, sorting and/or filtering as you do so, based on what the user needs. That last part has the potential to be a slightly sticky piece of cake if you tried to do it all yourself, but even then it is doable. Using the QuickSearch might work, but looking at the sample, it's pretty slow with even a small list (looking at the table example), so with such a large data set, it may not be much fun. Won't know until you try. There are also plugins (are there not?) which turn tables into sortable/searchable data sets. You could build one of those as an 'alternative possibility' for your users to look at.

The way it was done before involved two identical files being maintained simultaneously, one sorted by the form ID (AA0001) and the other by name. The list of forms is nothing to sneeze at ... the first page includes a list of over 1800 forms. My first stab at a solution moved everything into a single unordered list. I was able to assign classes to each list item for the alpha character, the ID and type. Clicking on the appropriate links would show only those items which you selected. I also plugged in Rik Lomas' awesome QuickSearch plugin to quickly search the list. The only drawback was that the group responsible for maintaining the list of forms had to choose whether they wanted the list sorted by name or form ID. They chose name. Last week though, they decided that wasn't good enough and they needed to be able to sort by either name or form ID, so I've been handed this project again and told to make it work more to their liking. A table would break from the way they've organized these forms for years now, so they're really not interested in something like that, so it'd really need to be a list. The forms need to be able to be sorted alphabetically by name or form ID as well as organized by category. My first idea was to build a big (and I mean BIG) JSON file that would store all the information for these forms. I'd then be able to parse through the JSON object and build the list on the fly based on what they clicked. Of course, we're talking about a JSON file that'd probably be over 2000 lines and would have to be parsed every time they click something (I'm not sure if I could call in the JSON file and have it available instead of using $.getJSON). Then there's the issue of searching. Obviously QuickSearch works great, but how am I going to search through a static file without throwing everything on to the page? As you can see, I've begun brainstorming some ideas, but I'd really love to hear what other solutions come to mind for you guys. Any ideas you have would be awesome. Thanks!

Re: [jQuery] How should I structure this?
On the backend you could add a timestamp for when items are added to the database. Then your query would return anything with a timestamp newer than the last time you asked for items. in client js: last_request = time(); Then send the time along with your request to the server script. on the server: ?php $query = select * from `item_table` where `added_on` $_POST[last_request]; ?

HI James,
I had updated to the latest JQuery the other day hoping it would solve my
problems. At first I was thinking the issue might be that I was needing some
plaugin for non-IE browsers or perhaps there was bug in my version of
jquery. I can see now that jquery requires a slightly different mind set and
a new set of techniques that I have never used. Being a noob at jquery I

you have any suggestions?

Using jQuery, you have basically two options:
- re-bind the event again
- use the new live() function (recommended, requires jQuery 1.3+)
For live(), you replace:
$(.galleryNavHA).click(function(event)
with:
$(.galleryNavHA).live(click, function(event)
(doc: http://docs.jquery.com/Events/live#typefn)
Then you would not have to re-bind again later on. This is using a
technique known as Event Delegation.

[jQuery] Re: ajax.load(url) working in IE only
Ok James, just one question though. I am using CI-CMS and I have my gallery
page is contained in a wrapper used for every page on the site. So if I add
the binding in the page head (which is shared for all pages) the gallery
classes tags do not exist. Will this cause an issue. If it does then I need
to modify the js in the head when building up the gallery page contents.
Again, I thank you for your help. I'm an old C/C++/Pascal /ADA/Fortran guy
so I am not well versed in javascript or ajax. My code was mostly taken from
some early ajax/php books. But I am eager to learn the proper ways of doing
ajax and using jquery. It seems to have some amazing functionality built
into it.

The issue is not the anchor tag around the image. The issue is how
your events and actions are working. This is what your script is
doing:
- A user clicks on the image (the a link)
- This call updateGallery()
- updateGallery() sets an event - when clicking on any a link with
class galleryNavHA, you do the AJAX
- End
This doesn't actually do the AJAX. It just binds a click event.
Suppose a user clicks on that (or any) image again:
- User clicks on the image
- This calls updateGallery() AND the binded event to do the AJAX.
- updateGallery() sets another, duplicated, event - when clicking on
any a link with class galleryNavHA, you do the AJAX
- End
What you need to do is bind the click event on page load. If the user
has no Javascript enabled, the click binding will not be done, and the
a link will do its default job.
script
$(function() {
$(.galleryNavHA).click(function(event){
var href = this.href;
var rel = this.rel;
// do your ajax stuff
return false;
});
});
/script
a class=galleryNavHA rel=http://hooker.dotnetnebraska.com/
index.php/gallery/getAjaxNavH/4/101 href=http://
hooker.dotnetnebraska.com/index.php/gallery/getAjaxMainImage/4/101
img class=galleryNavHImg src=http://hooker.dotnetnebraska.com/
images/o/30big.jpg //a
This keeps the Javascript outside of the HTML also.

Hi Yes, I have the anchors because I need to insure there is some
functionality when js is not available. I have used anchors with my own
ajax
code without issue as long as I return false from the js function call.
Is
this a known issue with JQuery, that you can't provide a default action
for
an anchor? If it is, how to I insure the image is still available if
javascript is turned off?
Thank you for you help.

Not looking any further, you have anchors with inline onclick events

a onclick=javascript:updateGallery(); class=galleryNavHA...
You might want to rethink it a little bit :P

Hello,
I have use ajax.load in the following function to load both a main
image and an image navigation bar on a single page. The fucntion
works
in IE but not in FF or Chrome. I am not fluent enough (yet) with
javascript or firebug to figure out what is happening. The demo page
can be found at:http://hooker.dotnetnebraska.com/index.php/gallery
/*
* Updates Photo Gallery
*/
function updateGallery() {
$(.galleryNavHA).click(function(event){
event.preventDefault();
var href = this.href;
var rel = this.rel;
//$(.galleryMainImg).fadeOut(slow);
$(.galleryMainImageDivCls).load(href);
//$(.galleryMainImg).fadeIn(slow);
$(.galleryNavDivCls).load(rel);
return false;
});
}
Any help getting this to work would be greatly appreciated.
Thanks,

If you ask me if it can be done. The answer is YES, it can always be
done.
The correct questions however are... What will it cost, and how long will
it
take?

[jQuery] Re: ajax.load(url) working in IE only
Thank you James. Coming form languages like C/C++ if I were to make a call
to a non-existent method, you would see errors. So I sorta expected the same
thing here. I guess I have a lot to learn yet. But with the help of good
people like you I'll get there.
Thank you again for you help. I will now make the changes to my code and see
what happens.
Sincerely,
Randall

If you don't have any other classes galleryNavHA in your code nothing
will happen. Though it might be very minor overhead since jQuery will
try to do a check for it to bind the event. Just make sure you don't
use the class elsewhere or else it might cause unexpected things to
happen.
If you have to use the code on several pages of your website might as
well have it on all your pages.
It's also okay if you don't put the script in your HEAD and put it in
your BODY. It'll still run fine, but it is mixing Javascript with
HTML, which isn't good practice. It's all up to you how you want to do
it.

Ok James, just one question though. I am using CI-CMS and I have my
gallery
page is contained in a wrapper used for every page on the site. So if I
add
the binding in the page head (which is shared for all pages) the gallery
classes tags do not exist. Will this cause an issue. If it does then I
need
to modify the js in the head when building up the gallery page contents.
Again, I thank you for your help. I'm an old C/C++/Pascal /ADA/Fortran
guy
so I am not well versed in javascript or ajax. My code was mostly taken
from
some early ajax/php books. But I am eager to learn the proper ways of
doing
ajax and using jquery. It seems to have some amazing functionality built
into it.
Thanks again,
Randall
