jquery的event.stoppropagation()是兼容firefox、chrome的，但不兼容ie
兼容写法：
if (event.stopPropagation) { event.stopPropagation(); } else if (window.event) { window.event.cancelBubble = true; }
window.event在ie和chrome上是有的，firefox上没有window.event，需要函数中参数带入
$(".dom").click(function (event) {
if (event.stopPropagation) {
event.stopPropagation();
}
else if (window.event) {
window.event.cancelBubble = true;
}
...
});
