Just a Quick little snippet really..
Over at JqueryForDesigners.com @rem mentioned about checking if an element exists or not, I’ve been doing this for some time using the following snippet:
jQuery.fn.exists = function() {
return (this.length > 0);
};
to use it you can now do this:
if ($('#elem').exists()) { /* do something */ }
Hope this is helpful to some people
hummm … i don’t think it’s that this makes a lot of sense,
since we should just do this:
if ( $('#elem').length )or this
if ( !$('#elem').length )but i did similar things some time ago (slooow things ;O)
and i understand that jquery isn’t really associative.
just go on with that, i like your way of thinking.
