jQuery click event handler is called twice for a checkbox

Question

I have a problem with the following code in an ASPX page:

Answer 1

I have just experienced the same thing, but am not sure that event bubbling is causing my issue. I have a custom tree control, and when an item is opened, I use $(id).click() to attach a handler to all elements of a certain kind.

I suspect that this means that existing items elsewhere that already have the event, may then have it added again. I found that unbinding everything then re-binding solved my problem, thus:

$('img.load_expand').unbind("click").click(function()
{
  // handler
});
