本文实例讲述了JavaScript事件委托用法。分享给大家供大家参考。具体如下:
var addEvent = function (elem, eventType, func) { if ( elem.addEventListener ) addEvent = function (elem, eventType, func) { elem.addEventListener(eventType, func, false); }; else if ( elem.attachEvent ) addEvent = function (elem, eventType, func) { elem.attachEvent('on' + eventType, func); }; addEvent(elem, eventType, func); }; var delegateEvent = function (elem, childElems, eventType, func, args) { addEvent(elem, eventType, function (e) { var evt = e || window.event; var elem = evt.target || evt.srcElement; if ( elem.nodeName.toLowerCase() == childElems.toLowerCase() ) { func(elem, args); } }); };
希望本文所述对大家的javascript程序设计有所帮助。
