First, let’s take a look at the JS event model. The JS event model is upward bubbling. For example, after an onclick event is triggered on a certain DOM element, the event will propagate upward following the node until a click event is bound to a certain parent node. , if not it will go up to the root of the document.

Prevent bubbling: 1. stopPropagation() for non-IE browsers. 2. The cancelBubble attribute is true, for IE browser,

Jquery already has a browser-compatible method, event.stopImmediatePropagation();

$(document).one("click", function () 
{//对document绑定一个影藏Div方法
$(myDiv).hide();
});

event.stopPropagation();//阻止事件向上冒泡
});
$(myDiv).click(function (event) 
{

event.stopPropagation();//阻止事件向上冒泡

});
　　　　function showDiv() 
{
$(myDiv).fadeIn();
