prop() Bug in IE9

[ganhuan@…]

html code :

<div hidden="true"> </div>

when using $.prop("hidden") in IE 9,it returns "undefined",but other brower such as firefox\IE 7\IE 8\Chrome returns "true" as expected. <a href="​http://jsfiddle.net/Ap2L4/">code in jsFiddle</a>

​prop is a low-level method that returns whatever the property value is in the browser. Although results may be different in different browsers, manipulation of these values would be disastrous.

The current result seems like a beneficial feature to me anyway, it's pretty clear from it that IE9 does not support the HTML5 hidden attribute. I can't see why we'd want to shim the property and mask the browser's lack of support for it.

Thanks for your request,but the problem is that I change the attribute "hidden" to any other name , for example "notShow","ab" and so on,it doesn't work in ie 9 any more.At contrast, if i use getAttribute("hidden") of dom,i can get the value of "hidden",see code below. Code :alert($("#test").get(0).getAttribute("hidden"));

HTML doesn't map all attributes to properties by default, only a small number of them. If you want the attribute, use .attr() and not .prop(). ​http://jsfiddle.net/Ap2L4/1/
