a confuse about jquery live() method parameter

Question

suppose I have a nomal function:

    function begin(e) {
        e.dataTransfer.effectAllowed = 'copy';
        e.dataTransfer.setData('text', this.id);
    }

I want the same function could appear in one element's live function:

    $('img.clone').live('click', function (e) {
        e.dataTransfer.effectAllowed = 'copy';
        e.dataTransfer.setData('text', this.id);
    })

situation1:the firebug would say the e.dataTransfer is undefined? however,if I change to this :

$('img.clone').live('click', function () {
       begin(e);
})

this could not doesn't work ,it also says e.dataTransfer is undefined,

but if I use it in addEventListener('dragstart', begin, false),this could work?

So how can I pass the "e" correctly in live() method?

Answer 1

e.dataTransfer is undefined not e.

Try

e.originalEvent.dataTransfer...

jQuery stores the original event in e.originalEvent, the e itself is not a real event object but a normal object that jQuery created.
