我为我的段落绑定了jquery Tap事件。这里当我点击IE8中的目标时,event.originalEvent返回为"未找到成员"
我的代码

<body>
<h3>Long press the square for 750 milliseconds to see the above code applied:</h3>
<div class="box"></div>
<script>
$(function(){
$( "div.box" ).bind( "tap", tapholdHandler );
function tapholdHandler( event ){
var origEvent = event.originalEvent;
setTimeout(function(){
console.log(origEvent);
})
$( event.target ).addClass( "taphold" );
}
});
</script>
</body>
</html>
在其他浏览器中,它的工作原理如何解决此问题?
