[jQuery] jQuery Functions
Firstly hello everyone and apologies for breaking new ground in terms
of simple idiot questions.
Ok so I'm trouble doing something I would consider as simple with
jquery.
I have a form and i want to run a common function (that checks a bunch
of inputs) that will be run when certain fields blur. working off the
blur field is not a problem, but parsing the function is... example
below. Looking at callback's in jQuery I'm still a bit confused and i
cannot find anything floating around the net that does similar to what
i want to do (common function invoked from multiple different fields).
function EvalFields() {
var arrFieldNames = array;
var boolFields = boolean;
boolFields = true;
alert(running); // easy way to know if your running the code
or not
arrFieldNames[0] = #frmField1;
arrFieldNames[1] = #frmField2;
arrFieldNames[2] = #frmField3;
arrFieldNames[3] = #frmField4;
arrFieldNames[4] = #frmField5;
for (var x=0;xarrFieldNames.length;x++) {
if( !$.(arrFieldNames[x]).empty() ){
boolFields = false;
}
}
if (boolFields == true) {
$.(#frmHiddenField).val(1);
} else {
$.(#frmHiddenField).val(0);
}
}
^^ this is the function I want to use. It just cycles through a bunch
of fields and if they all have content it'll flick a switch for server
side processing later on.
$(#frmField1).blur(function () {
EvalFields();
});
$(#frmField2).blur(function () {
EvalFields();
});
$(#frmField3).blur(function () {
EvalFields();
});
$(#frmField4).blur(function () {
EvalFields();
});
$(#frmField5).blur(function () {
EvalFields();
});
^^ the on blur events should be fine right?
I'm assuming that I'm not defining the function properly and/or
passing jquery through(maybe i'm not event getting this far!)...
The whole point of this was to not write the exact same code for the 5
odd, specific, blur events but i've wasted so much time on this i need
to seek assistance.
Can anyone help me with this? Thanks in advance.
p.s. all form elements have appropriate id's set, etc. and I'm
successfully using the Validation plugin already.

Thank you very much.
It took me another hour but I managed to debug the code and get it all
working, thanks again.

Hi,
instead of doing a complicate string handling you could simply use
window.location.hash:
$finalurl = window.location.hash;
For debugging I would do it step by step and not all in one line:
var el = $($finalurl+ :first);
var src = el.attr(src);
var src_split = src.split(.);
var new_src = src_split.join(_on.);
el.attr(src, new_src);
This way you can use firebug to step through your code and see which
statement produces the error.

Hi, pulling my hair out here.
When the page loads I'm collecting a variable from the url which
corresponds to the class of an image. I want to then change the image
source. I'm doing this because the page doesn't reload and the menu
needs to respond to the content if you get my meaning.
$url = location.href;
$hashtag = $url.search(/#/)
$url2 = $url.split(#, $hashtag);
$finalurl = $url2[1];
This is the code I use to get the class name. When I try to add
$finalurl to the attr (see below) it throws an error (undefined,
console.log shows it is defined within the if statement).
$($finalurl).attr(src, $($finalurl).attr(src).split(.).join
(_on.));
Full code:
$url = location.href;
$hashtag = $url.search(/#/)
$url2 = $url.split(#, $hashtag);
$finalurl = $url2[1];
counttemp = 0;
if (counttemp == 0) {
console.log($finalurl);
$($finalurl).attr(src, $($finalurl).attr(src).split(.).join
(_on.));
counttemp = countemp + 1;
}
Any help would be greatly appreciated.
[jQuery] Re: Change image attribute based on variable
Thanks, I ended up playing around with the url before I passed it into
the function, didn't realise I could do it like that.

Also, $($finalurl) likely won't select anything because you're only
passing the classname. It needs to be in the form '.classname'
(prepended by a dot). Try $('.'+$finalurl)

[jQuery] Re: Ignoring field within whole DIV
Sorry, I posted the wrong bit of code. My .ajaxLoad code is:
$pastemonkey('#content').not($pastemonkey('#PasteTags')
[0]).ajaxStart(function(){
$pastemonkey.blockUI();
});

Hi there,
I am running into a little problem, I cannot seem to get my code to
work to ignore 1 field inside a DIV. I have a .ajaxLoad() on the div,
that fires block UI when the content of the DIV changes, however also
inside the DIV I have a field that has a autocomplete attached to it.
When I type in this field, it fires the .ajaxLoad() and the block UI.
My code is below:
$pastemonkey('#PasteTags').livequery(function(){
$pastemonkey(this).autocomplete('/tags/find/', {multiple:
true,
matchContains: true});
});
$pastemonkey is my own var for $ using .noConflict. I've tried using
:not but couldn't get it to work. Can anyone help?

[jQuery] Re: Problem with AJAX and links
Bahh, I've found a bug. In the code when I get type, I check to see
if type == whatever. But it seems if my links have more than 1
class, it fails. For example my code may have a
href=/admin/posts/add class=add admin-linkAdd Post/a - this is
ignored.
Whats the best way to check to see if a link contains the class,
without doing a == selection on it?

Hi Sean,
Thanks, that seems to have done the trick - although it broke the Tabs
plugin I was using in my admin interface. I've created a workaround
and this works perfectly:
function hijackLinks(root) {
$('a',root).click(function(){
var type = $(this).attr('class');
if (type == admin-link) {
// If admin link, load into sub-admin area
$('.admin-area').load(this.href,function(){
hijackLinks($('.content')); });
return false;
} else if (type == no-ajax) {
// If no ajax link, ignore
} else {
// Normal content area link
$('.content').load(this.href,function(){
hijackLinks($('.content')); });
return false;
}
});
}
$(document).ready(function() {
hijackLinks(document);
});

Hi Tane,

$('a',root).bind('click', function(){

I would change this function to this instead of doing all that ajaxStart/Stop:
function hijackLinks(root) {
$('a',root).click(function(){
$('.content').load(this.href,function(){
hijackLinks($('.content')); });
return false; });
}
Then you only need to run your: $(function(){ hijackLinks(document); }

[jQuery] Problem with AJAX and links
Hey folks,
I've been working on this one with a little help, but i'm now stuck.
I have an AJAX interface, where I want all internal links to load
content into a specific div called .content. The issue is it works,
except for link in content thats loaded into the div.
So far, here is what I have:
function hijackLinks(root) {
$('a',root).bind('click', function(){
$('.content').load(this.href);
return false;
});
};
This is the function that I pass the clicked link in to, I take it's
href and load the page into the .content div.
$(document).ready(function() {
hijackLinks(document);
});
This loads the function on first load. Then I do this:
$().ajaxStart(function(){
$.blockUI
hijackLinks($('.content').get(0));
});
$().ajaxStop(function(){
$.unblockUI;
hijackLinks($('.content').get(0));
});
i've called the function on both ajaxStart() and ajaxStop() to reload
the function into the page, but doesn't seem to work. Can anyone
maybe help?
THanks,
Tane
[jQuery] Webrocket: My new jQuery-powered CMS
Hey folks, Bit of a shameless plug here, but I'd like to announce to you my project - Webrocket. It's a CMS built on CakePHP, and using jQuery for all it's JavaScript. Currently it uses AJAX functions to load most of the pages. I've currently been working on this for a work project, however the source code is being released under a MIT/GPL Dual licence. It also uses the Forms plugin, blockUI plugin and Tablesorter. You can check out a demo at http://66.160.135.85/ The official project page is at https://cakeforge.org/projects/webrocket/ Please note, this is an early alpha, as such the code is messy and buggy. Most statements are inline, however I will be changing that to core functions in the next week. Please feel free to comment, and if anyone feels like contributing code please feel free to contact me. Finally the site blog is at http://webrocket.wordpress.com Tane Piper
