The relationship between the event of jquery and Originalevent and the usage of event object

In jquery, the event that eventually passed in to the handler has been normalized by jquery,

Its original event object is stored in the Originalevent attribute of the event object,

Each event is an instance of Jquery.event

There are six methods stored in the prototype chain,

The code is as follows	Copy Code
JQuery.Event.prototype = { preventdefault:function () { //Cancel event default behavior     },  stoppropagation:function () { //Cancel event bubble up     },  stopimmediatepropagation:function () { this.isimmediatepropagationstopped = returntrue; this.stoppropagation ();     },  Isdefaultprevented:returnfalse, Ispropagationstopped:returnfalse, Isimmediatepropagationstopped:returnfalse };
