Is there a significant performance impact on detecting for events on
elements which are not found on a certain page?
For example, when using jQuery to code large sites i have always used
a global event include i.e events.js to attach a $(document).ready for
all possible site events. This allows the script to be cached on first
page load, and all "inside page" events would not have to download
page events with a separate specific uncached file, i.e.
"somepage.js".
I've always wondered though if this approach could negatively impact
page performance.
Would for example having a 10kb file with events like
$('#very-specific-id-not-on-every-page').hover(function(){
// do something
}, function() {
// do something else
});
have a noticable performance hit? Do you think that effect would be
greater than the effects of not caching those events in a global
include?
I realize this isn't a cut-and-dry issue but i figured you guys might
have some insight into "best practices" for jquery.
thanks,
