Jquery :: Dynamicly Inserted Content With Change() Event Handler?
Jan 28, 2009
Its a very convoluted title, but not sure how to phrase it.I'm using the latest version of jquery. i have a function that creates a new row given an onchange event for the primary select box. This new row contains another drop down box that i want to bind another onchange event. Problem is when the child drop down change event is triggered, if there are multiple children, the alert pops up for the number of children that it has.. horrible explanation heres the code:
Code:
$('#perph_type').change(onSelectChange);
function onSelectChange(){
[code]....

I'm trying to change a word in an animated collapsible div script from Dynamic Drive. When clicking "Hide" I want the word to change to "Show". I have part of the script, but it's not working correctly - it just removes "Hide" when clicking on it. See the example here.
The code so far is this:animatedcollapse.ontoggle=function($, divobj, state){ //fires each time a DIV is expanded/contracted
//$: Access to jQuery
//divobj: DOM reference to DIV being expanded/ collapsed. Use "divobj.id" to get its ID
//state: "block" or "none", depending on state
if ($('#'+divobj.id+'-toggle').length==1){ //if toggle link has id 'divid-toggle' defined
if (state=="block")
$('#'+divobj.id+'-toggle').prepend('<span class="prefix">Hide </span>')
else
$('#'+divobj.id+'-toggle').find('span.prefix').remove()
}}
I'm totally new to jQuery.

it's possible to bind a function to an element that is fired if that element is 'moved'/repositioned via the browser.
For a more specific example what I have is a function that calculates height and width of certain elements to allow them to all fit nicely on the page without having scroll bars, and this is bound to the window onresize event. It works nicely most of the time but occasionally something will change the height of one of the elements and this effectively bumps one element right off the page.
So I'm wondering if its possible to have an event bound to an element that is fired when an elements position is moved/recalculated by the browser? Short of polling every second or so, to see if it has moved/recalculate layout.

i'm using URL... to load and preview music on my page.It all works really well, when you write pure static html code with just [code]And it will automaticly transform that url into a working custom-player. Done with the soundcloud api.But when i use $.getJSON and dynamicly get down a list of urls that i try to insert with:[code]*side-note(it's the same result with $('#addbtn').click, just wanted to try live as i hoped it would update the elements upon being added. But did not work out.)The url gets inserted into sc-player class div, but the rest never gets transformed into the custom-player with the sc-player.js script.It just remains an ordinary a href. It is as if the sc-player.js never is being "loaded" which i can understand why it won't. Question is how do i get it to successfully transform my urls that are being dynamicly added with javascript into the custom-player instead of just the url to the song?

I want to change the event handler for a form field, using JS code. But
there doesn't seem to be a way to reference it. MyForm.SomeField.onChange
is undefined. Anyone know if there's a way to do this?

Let's say I have this code:
$("p").click(function(){
alert("You've clicked on a paragraph");
});
$("body").append('<p>A paragraph</p>');
But when I click on the new paragraph, the event listener for p isn't running.

I am using a WYSIWYG web editor (Serif WebPlus X4; for a whole range of reasons - please don't turn this thread into a discussion of the pros and cons of WYSIWYG! ). It has a tool to create a site search facility, whereby you add a text box to accept the search terms, and specify an iFrame in which the results appear. The source of the iFrame is not specified as a page, but rather the content is generated and inserted by the search JavaScript that runs when the user searches the page.
I really don't want the results to be in an iFrame, because I think it looks a mess when the page and the iFrame both scroll. To avoid this, I'm trying to get the iFrame to resize to fit the results, so it won't need to scroll. (Of course, the alternative would be to change the JavaScript so the results are placed directly onto a page rather than in an iFrame, but because of the way the WYSIWYG editor works, that's less straightforward).
I've found many scripts online that would let me change the size of the iFrame based on its content, but they all assume that the content is coming from a file saved on the server, and work by checking the height of the file's content, and inserting that value as the height of the iFrame. Now, the problem is that when I use these scripts they cause the iFrame to become 0px high, I assume because the frame doesn't have a fixed source that can be measured, but rather gets its content fed in from the search JavaScript.
Can anyone help me figure out a way to resize the frame even though its content is dynamically generated as the page with the frame is loaded? I've copied below the search script and the html page with the iFrame that needs to resize. Ideally, whatever solution I use shouldn't involve editing the .js file I've attached, since this is generated automatically by the WYSIWYG program.

I'm trying to bind an event handler to a button in a page loaded via Ajax. This procedure should apply to every page I have to load via Ajax. I have tried two things: first, I declared the 'click' event handler for the button like this, and just did my ajax request. Here's the code:
$("#close_button").click(function(){
alert("This should popup");
});
$.ajax({
url: 'js/ajax/text.html',

I'm creating a drop down menu so that when a user clicks on the drop down arrow and then hovers over one of the options, a bubble comes up and does a validation. The thing is that everything works fine in Firefox, but not in IE or Chrome. The problem is that the .mouseover() function doesn't work on the <option> tags in IE and Chrome, but it works fine in Firefox because apparently FF is the only browser that supports it.

My plan is to create a JavaScript class, with some functions and variables, and one of the functions is called when a user clicks on a certain element. However, I need to find out the ID of the element that was clicked (in the example, that of the <p>) for further processing. It looks basically like the following:
[Code]...
The result was very crazy, because console.log(this) gave me the node as result, and console.log($(this)) did the same only as jQuery node, but trying to find out the attribute via jQuery gave undefined as result. I haven't checked if this.id would work (should probably), but I'd prefer to keep the whole script in jQuery, if possible. I suspect it may be an overusage of the 'this' keyword, but if so, what's the proper way to do it?

i'm looking for the best way to use global properties that defined at class level insid event handler functions.
for example :
function MyClass() {
this.v1 = "hello";
this.v2 = {name: 'joe', age:'30'};
this.link1 = $("<a/>", {id: "link1"});
[Code].....
actually, in link1Handler 'this' returns to link1 not to main class. so how to get class properties or functions inside the private functions of the same class?

I have a <div> containing 3 buttons. The buttons have id's like this:
Button 1: btnFoo
Button 2: btnBar
Button 3: btnBaz
I'd like to add an click event to each button to call a function named [button ID]_click():
i.e.
btnFoo_click()
btnBar_click()
btnBaz_click()
So far I have this:
$("#divButtons button").each(function() {.
$( this ).bind("click",function(){
eval(($(this)[0].id) + '_click()');
});
});
This works but is there a way without having to use eval and still utilizing the lovely .each function?

I am have an MVC app that generates a list of rows, of which one of the columns is a button. Here is the rendered HTML for the buttons:
<input
id
="btnUpdate21"
type
="submit"
value
="Approve"
synchId
="21"
/>
<input
id
="btnUpdate22"
type
="submit"
value
="Approve"
synchId
="22"
/> .....
Following is my selector that I use to bind the buttons to my click event:
<script
type
="text/javascript"
charset
="utf-8"
>
$(document).ready(function
() {
$('input[id^="btnUpdate"]'
).click(promptForSynchDate);
});
I have been trying to access the button Id, though what I really need is the attribute synchId, to use inside of a modal. I have so far been unable to access either one of them. My modal works fine. But the value of either attribute is always "undefined".
Here is my click event handler: (I stuck the alert in there just for debug purposes)
function promptForSynchDate() {
$(document).ready(
function () {
var test1 = $(this).attr('id');
alert(
'test1 is : ' + test1);
$(
'#approve-synch').dialog({ .....

I have a basic HTML form with a button that submits the form via jQuery's $.post to a processor. That processor returns the identical form, including any errors below any of the elements e.g. input, textarea, etc. The response also has a new submit button to submit the form once more, however, because I'm retrieving a giant string with HTML elements and because jQuery already loaded, that new submit button doesn't do anything. How can I parse jQuery's response for that button and assign a handler so that when the button is pushed, it submits the form again?

I have some code that's a more involved version of this:
$('#container_div').delegate('.trigger_button', 'click', function() {
$.post('handler.php',
{ id: $(this).siblings('.item_id').val() },
function(data) {
[Code].....
Normally, when I use .post in an event handler, "this" refers to the object that triggered the event. That doesn't happen in this case. When I use "this" the first time, to pull data parameters, it refers to the .trigger_button. But inside the .post callback, it refers to the AJAX call object instead. I don't think that's how it's supposed to work, is it? Is this a bug?
