I have a bit of code where I am looping through all the select boxes on a page and binding a .hoverevent to them to do a bit of twiddling with their width on mouse on/off.
This happens on page ready and works just fine.
The problem I have is that any select boxes I add via Ajax or DOM after the initial loop won't have the event bound.
I have found this plugin (
jQuery Live Query Plugin), but before I add another 5k to my pages with a plugin, I want to see if anyone knows a way to do this, either with jQuery directly or by another option.
$(staticAncestors).on(eventName, dynamicChild, function() {});
Prior to this, the recommended approach was to use
live():
$(selector).live( eventName, function(){} );
However, live() was deprecated in 1.7 in favour of on(), and completely removed in 1.9. The live() signature:
$(selector).live( eventName, function(){} );
... can be replaced with the following
on() signature:
$(document).on( eventName, selector, function(){} );
For example, if your page was dynamically creating elements with the class name dosomething you would bind the event to a parent which already exists, often document.
$(document).on('mouseover mouseout', '.dosomething', function(){
// what you want to happen when mouseover and mouseout
// occurs on elements that match '.dosomething'
});
Any parent that exists at the time the event is bound is fine. For example
$('.buttons').on('click', 'button', function(){
// do something here
});
would apply to
<div class="buttons">
<!-- <button>s that are generated dynamically and added here -->
</div>
