Bug? Draggable and unbind.

in Using jQuery UI • 12 years ago

Hi,

I've noticed that if you make an object draggable and then unbind it, you can't make it draggable any more. See sample code below.

<ul id="foo">
<li id="bar">bar</li>
<li id="baz">baz</li>
</ul>
<script type="text/javascript">
$(document).ready(function() {
$("#bar").draggable(); // Can drag
$("#bar").unbind();
$("#bar").draggable(); // Can't drag any more
});
</script>

Is that a bug?

Cheers,

Julien

Not a bug. Your use of unbind() is just pretty indiscriminate. When using unbind(), I am usually careful to

specify the event AND the handler I want to get rid of, lest I end up in your situation and kill other people's event handlers...

Sure but in this case I do want to kill every event attached to this object. And then I want to re-attach a draggable functionality to the object. Why can't that be done, and is there a way around?

you would need to remove draggable from it before you add draggable back to it. draggable is not an event, it is a widget.

$("#bar").draggable("destroy");
