获得原始目标的最佳方法

在 jQuery(或一般的浏览器 javascript)中获取事件的原始目标的 jQuery 和/或最佳实践方法是什么.

What's a jQuery like and/or best practices way of getting the original target of an event in jQuery (or in browser javascript in general).

我一直在使用类似的东西

I've been using something like this

$('body').bind('click', function(e){
        //depending on the browser, either srcElement or 
        //originalTarget will be populated with the first
        //element that intercepted the click before it bubbled up
        var originalElement = e.srcElement;
        if(!originalElement){originalElement=e.originalTarget;}                         
});

这可行，但我对两行特征嗅探不满意.有没有更好的办法?

which works, but I'm not pleased with the two line feature sniffing. Is there a better way?

推荐答案

var originalElement = e.srcElement || 一行代码就可以搞定e.originalTarget; 但它不像 JQuery ;-)

You can do it in one line with var originalElement = e.srcElement || e.originalTarget; but it ain't pretty JQuery-like ;-)
