Frequent execution of jQuery Ajax requests is evident

Using a live operator, I attach a click function to a li-element:

$(".UListView li input.iconbutton.click").live("click", function(e){

e.preventDefault();
[...]
$.get("ajax/categorylist.php?appendcategories=true&parentcat="+currentid+"&side="+side, function(data){
[...]
});

});

In most cases, it works perfectly and is executed once. However, there are instances where the ajax request runs 2 or more times:

This is what shows up in firebug: (Executed two times)

jquery.min.js (Line 4)
GET htt-p://localhost/request.php?....    200 OK     11ms   
jquery.min.js (Line 4)
GET htt-p://localhost/request.php?....    200 OK      19ms

This completely disrupts my layout as elements are added multiple times to the DOM.

Does anyone have insight on why this is happening? Or any suggestions on how to prevent the "adding to DOM" code from running multiple times.

Answer №1

Make sure to insert e.stopPropagation(); within your code and also add return false; at the conclusion of the click event

Answer №2

If you find yourself binding the live event twice, make sure to implement the following code:

 $(".UListView li input.iconbutton.click").die("click");
   $(".UListView li input.iconbutton.click").live("click", function(e){
..
..
..
});

Sometimes, clicking a button once can result in the event being fired twice.

In such cases, hide the button after the click to prevent multiple submissions:

$(".UListView li input.iconbutton.click").live("click", function(e){

$(".UListView li input.iconbutton.click").hide();
..
..
..
});
