在过去的几个小时里，我一直在努力解决这个问题，但是如果没有最后一个 jquery 函数，我将无法继续，当我点击它时，我试图让卡片（国王是一张测试卡片）跟随我的鼠标. 当我点击它就消失了。

现在，我试图让图像跟随我的鼠标，但是当我点击它时它就消失了。它不会引发任何控制台错误，它只是消失了。我被要求发布整个代码，所以我已经完成了。

也为我工作。你需要分享你的整个代码或提供一个不起作用的小提琴

http://jsfiddle.net/SVKeE/

$(function() {
$('#playerHand').click(function(e){
    //$(this).removeClass('cardsHand');
    //$(this).addClass('clickedCard');
    $('img.heh').css
    ({
        'top': (e.clientY - 20), 
        'left': (e.clientX - 20)
    });
});
});

我尝试了您帖子中的代码。但除了卡片生成之外，它似乎并没有做太多事情。我认为您需要查看http://jqueryui.com/draggable

如果您可以拖动纸牌，您的纸牌游戏会更有用。
