我正在尝试使 jquery 中的 mouseenter 和 leave 事件起作用，但似乎没有任何效果。如果我在图像上拖动鼠标而不遍历浏览器上的其他区域，则 mouseenter 可以工作。整个页面如下所示。我必须使mouseenter和mouseleave事件工作。

而不是现场使用

$(document).on('mouseenter', '.wrapper', function() {
        ...
});

试试这个我改变的 jsFiddle：http: //jsfiddle.net/jjay225/r8PKc/2/ mouseenter工作正常，它改变了 css 正确。这是行$(this).find('.real img').css({'display':'block','top':'30px'});
