我有脚本喜欢

$('button').click(function(){

    var loc = $('.p1').data('location');
    alert('data location is'+loc);//SHOW THE DATA

    var num = 10;
    var count = loc;
    var element = $('.p1');
    var intv = setInterval(anim,1000); 
    function anim(){
        count++;
        num--;
        if(count==37){count = 1;}
        if(num==1){clearInterval(intv);}
        $(element).animateCSS('bounceOut',{
            callback: function(){
                $(element).attr('data-location',count);
                $(element).animateCSS('bounceIn');
            }
        });

    }
    anim();

});

使用上面的脚本data-location属性将更新为10,但如果我再次单击该按钮,数据位置仍然是1
