Now, if anything is returned from the extra function it will overwrite the return value of the event handlers. This should only effect custom events unless someone had an extra function that returned a value other than false which would have been ignored before.
Plugins will be most interested in:
- jQuery.data(elem) -> Unique ID for the element
- jQuery.data(elem, name) -> Named data store for the element
- jQuery.data(elem, name, value) -> Saves a value to the named data store
- jQuery.removeData(elem) -> Remove the expando and the complete data store
- jQuery.removeData(elem, name) -> Removes just this one named data store
jQuery's .remove() and .empty() automatically clean up after themselves. Once an element leaves a DOM document their events are no longer intact. Thus, statements like so:
{{{
$("#foo").remove().appendTo("#bar");
}}}
should be written like so:
{{{
$("#foo").appendTo("#bar");
}}}
in order to avoid losing the bound events.
