如何在Firefox JavaScript中访问非标准属性？

Question

Basically in IE you can do something like this:

<img metaDataAtt="type5" src="..." id="tag1"/>

and then in the JavaScript do something like

var theImg = document.getElementById("tag1");
alert(theImg.metaDataAtt);

However, in firefox you can't. Is there some sort of hack to get around this?

Thanks, Grae

Answer 1

document.getElementById('tag1').getAttribute('metaDataAtt');
