Question

How to read bound hover callback functions in jquery

Answer 1

A:

I'm not sure if this is what you mean, but you can bind custom events and then trigger them.

http://docs.jquery.com/Events/bind

So add your hover event, script the functionality you need for that hover, then trigger your custom event.

A:

Not sure if this will work, but you can try this:


<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <title>Jquery - Get, change and restore hover handlers</title>
        <script src="jquery.js"></script>
        <script>
            function setHover(obj, mouseenter, mouseleave) {
                obj.data("_mouseenter", mouseenter);
                obj.data("_mouseleave", mouseleave);
                obj.hover(obj.data("_mouseenter"), obj.data("_mouseleave"));
            }
            function removeHover(obj) {
                obj.unbind("mouseenter", obj.data("_mouseenter"));
                obj.unbind("mouseleave", obj.data("_mouseleave"));
                obj.data("_mouseenter", undefined);
                obj.data("_mouseleave", undefined);
            }
            $(document).ready(function() {
                var test = $("#test");
                setHover(test, function(e) {
                    alert("original " + e.type);
                }, function(e) {
                    alert("original " + e.type);
                });
                var saved_mouseenter = test.data("_mouseenter");
                var saved_mouseleave = test.data("_mouseleave");
                removeHover(test);
                setHover(test, function() {
                    alert("zip");
                }, function() {
                    alert('zam');
                });
                removeHover(test);
                setHover(test, saved_mouseenter, saved_mouseleave);
            });
        </script>
    </head>
    <body>
        <p><a id="test" href="">test</a></p>
    </body>
</html>

If not, maybe it'll give you some ideas.

Answer 3

+1 A:

Calling an event bind method (such as hover) does not delete old event handlers, only adds your new events, so your idea of 'restoring' the old event functions wouldn't work, as it wouldn't delete your events.

You can add your own events, and then remove them without affecting any other events then use Event namespacing: http://docs.jquery.com/Events_(Guide)#Namespacing_events

This answer improved my understanding of jquery and events, so I ended with changing the problem rather than finding the solution I originally wanted. I think the result is better than it would have been otherwise. Thanks.

Answer 4

A:

Maybe it would be easier to just hide the old element and create a clone with your event handlers attached? Then just swap back in the old element when you're done..
