JQuery :: Attach Events To DOM Elements Without "touching" The Html?
Dec 4, 2010
I have just started my adventure with jQuery. I wrote a post on a forum and a men wrote me:"Don't mix javascript with the html of the view as in your <body onLoad="load()">, but put it in a different javascript file thatyou include. In the JQuery tutorial there are example of how to attach events to DOM elements without "touching" the html. "I know how to put my javaScript code to the a ****.js file but I don't can not find any information how to do:attach events to DOM elements without "touching" the html. I was looking for a tutorial here but I couldn't find

Is there a way to change html tags without touching the inner html? For example, changing all h4 elements to an h2. Maybe something like this? jQuery('h4').replaceWith('<h2>' + (this).html + '</h2>');

I have been trying to do the following. Using JS I want to create an
input element (text box) and attach a event listener. I have done in
in two different ways. The first is using xml elements directly (as in
e4x) and the second using the dom method createElement (which is much
clunkier to write). I'd prefer the former. I've included a stripped
down example below.
It appears that when creating an input element using the line:
var inputBox = <input type="text" size="30" />
that it does not have the same properties as when it is created with:
var inputBox2 = document.createElement("input");
because when an event listener is attached using addEventListener, an
error is generated on the first, but not the second.
My thoughts on this are either
1. The namespace for the input element is not correct and whether input
can have a listener attached. However, my guess is that it would not
show up in the first div box. Code:

I am trying to create a script that onload will attach an onclick and onchange event to all fields.I have also tried using setAttribute instead of attachEvent and it still does not work.Basically what the events do is disable a interval when an input field is selected and enable the interval when it is no longer selected.

I am trying to "ajaxify" my site. Now I have one problem:
$("#posts").children().remove();
$("#tag-sidebar").children().remove();
$.each(data.Tags_Sidebar, function (indexInArray, valueOfElement) {
var insert = $("<li>");
[Code]......
Now when I click one of those links (href1, href2, href3) generated, the click event won't execute! What's the problem? Also, is it right that I have to transfer the valueOfElement over, like I did? What does stopEventPropagation do? Prevent the href from being navigated to? That's what I am trying to do.
The data object is JSON fed from here:[URL]
The HTML is here: [URL]

I have an list <li> of uploaded files. Next to each file is a remove button In my js file I have code like the following
[Code]...
Now if the user uploads a new file via ajax, the <li> list adds a new rown with a remove button
But this button doesnt bind to the click event oulined above. How can I enforce this without a page refresh. A page refresh binds the click event to the new row

I was interested by Paul Irish's presentationon best practices where he mentions building document fragments off-DOM:[URL]... (page 8) I was wondering about the possibility of having some kind of buffering capability in jQuery, eg:
var $buffer = $.buffer();
$bigGroupOfFrags.each(function(){
$buffer.add( $('body').append(this) ); // any DOM touches get buffered
});
$.buffer().flush(); // write to DOM
I know you can manage this manually as Paul states in his pre and I havn't thought about the implications too deeply, but a nice abstracted way to do this would bereally helpful.I've noticed when using new CSS3 styling like dropshadows, DOM touching get's really expensive.

Im working on a ajax app and not sure what is the best way to bind events to elements (performance wise).I have a number of elements with 'click', 'focus', 'keydown' events which can be assigned though the delegate to the parent, like so:$('#parent').delegate('#child', 'click', func.....)but is it better to add a delegate to the 'document' for multiple events and use IF statement to filter for elements which should fire an event, like so:[code]Each element can be replaced with an updated version retrieved from the server.

I define a "click" event on "a" tags in the ready part of a page. It fires just fine when I click on any "a" tag on the page. I then have a button which sets the content of a div using ajax. This content contains a couple of "a" tags. The issue now is that the "click" event does NOT fire when clicking on these tags. I suspect it is because they did not exist when the page was initially rendered. What is the "JQuery way" of dealing with an issue like this? Of course I cannot be the only one in the world who needs to return HTML with events from my ajax calls :-)

I have a dropdown which is created on the fly and it contains several options like below.
<option>A</option>
<option>B</option>
<option>C</option>
<option>C</option>
while creating this i am attaching the change event using live() function. On changing the above option i am recreating the above dropdown again. This dropdown in under a div .For eg:it has an id=1. During the time of recreating the above dropdown,i am dettaching the event handlers using die() and after that i remove the div with id=1.Again i will create a div with id=1 and a dropdown.
The problem now is that when i try to change the option two change events are triggered.I think the die() method haven't worked. Is it because i have created the dropdown under the div with same id?

I have an div element (lets call it div number 1) that I have attached a click event to using jquery.bind() method. That works fine. I then have another div element (div number 2) that is absolute positioned on top of div 1. Now div number 2 also has a click event binded to it, which works... the problem is when I click div 2 and the click event triggers, so does the click event from div 1... I don't want the click event from div 1 to fire.

Using $.get() and insertBefore() work great for what I'm doing. But, the data I insert does not respond to events that I have set up. I'm notsurprised by this. I'm sure there is something extra I need to do. But, what is that?

In the examples for live() and delegate(), the selectors match at least one element that already exists. Will either of these commands work on elements for which there is no match at all on page load?
In my case, I want to bind a keyup event to the textareas that jeditable creates. I could probably create custom plug-in (to the plug-in :) to do the job, but I'd like to use live or delegate if they would work.

Is there an easy way to tell which function is modifying a given element? To oversimplify my problem, I have a div that is mysteriously being cleared out about a second after it gets populated. I have been trying to determine why it is getting cleared with no luck. The website is basically Perl, Mason, and Javascript. I've tried setting breakpoints using Firebug and the IE Development Toolbar, but in both tools, the debugger runs out of code to show before the problem occurs.

I'm using some click events on normal <a> tags. When I rewrite the links within a html() method call, the click events no longer work. I've set up a very simple example here:When the page is loaded, clicking either of the 'link 2' links displays the correct information.When 'link 1' is then clicked, the main information is redisplayed. However, now, the 'link 2' link in the main paragraph doesn't work, although the 'link 2' link in the menu does.

I have been trying to use jquery function .html() but I noticed that it clears all events that are attached to the selectors. Is there a way around this issue? I want to change the content and keep the events.
I am aware of live and delegate functions but I am making changes to an external page so I do not have control over attaching events or knowing what they are at the first place.

I have a problem with jQuery appending new text to a div - but then not firing events attached to the inserted text.Let me explain. I have a div that contains a number of divs - the div has a link and a hidden form. Clicking on the link fires a slideToggle event which reveals the form.When you submit the form AJAX handles it and jQuery builds another div with the correct link and the correct form which it sticks on the end of the list. That all works fine and dandy.What I want to be able to do is to click on the newly-added link and have it behave in the same way as the other elements that were on the page when it was built. However, nothing happens when you click on it. Zip. Nadda. Rien du tout.Usually I have found a way round the problem - but I am slightly stuck on my current project. Apart from forcing a page reload, is there any way to get the browser to see the newly inserted link and apply the jQuery action to it?

I've used to an AJAX call to load a HTML table into div. This is working successfully. I know want to use a click event on buttons located within the inserted table.
The click event is triggering on buttons outside the inserted table but not on the buttons within the table.
Do I need to call some sort of refresh function to so that jQuery is able to pick up these events?

1. Is there any possibility to find out if mouseover, mouseout or any other mouse event is taking place for the given element right now?
2. Is there any possibility to find out for which element such event is taking place right now?
