jQuery : Click and clone bug

Click on a link, then I'd like to execute an animation after cloning an element. But I've unexpected results. To test : http://jsfiddle.net/r4BVb/3/

On multiple link click (like a geek), clone is proceed many times.

$('#clone').click(function(){
    $('.view_right').clone().prependTo('.overflowed');
    $('.view_right:last').css('display', 'none');
    $('.view_right:first').hide('slide', { direction: 'left' }, 300, function() {
        $('.view_right:las开发者_运维技巧t').show('slide', { direction: 'right' }, 300, function() {
           $('.view_right:first').remove();
        });
    });
});

How can I solve this ? Thanks

Here is the solution:

var called = false;

$('#clone').click(function(){
    if (called) {
        return;
    }
    called = true;

    $('.view_right').clone().prependTo('.overflowed');
    $('.view_right:last').css('display', 'none');
    $('.view_right:first').hide('slide', { direction: 'left' }, 300, function() {
        $('.view_right:last').show('slide', { direction: 'right' }, 300, function() {
           $('.view_right:first').remove();

            called = false;

        });
    });
});

Test it

Your code will add a lot of clones to view_right, so I suggest to check you're not adding too many like this:

if($('.view_right').length < 2) {

And the result will be http://jsfiddle.net/r4BVb/7/

Check this out: Using .one()

I'm effectively rebinding the click after animation and only listening to the click event once.
