Detecting a context-menu paste in the browser with jquery

问题

I am trying to check the length of the text in a textarea when someone pastes content in there via the right-click but can't seem to find how to do it.

回答1:

$('textarea').bind('paste', function() {
    var that = this;
    setTimeout(function() {
        var length = that.value.length;
        alert(length);    
    }, 0);

});

Works in Firefox 3.6, Chrome, Safari and IE9 beta. Does not work in Opera.
