JQuery 是：焦点在 IE8 中不起作用

Question

I check for focus on a text field with this:

if ($('#title').is(":focus"))

<input type="text" id="title" value="Write your post..." />

every other browser determines this as true, IE8 does not. Does this work in IE8?

Answer 1

This should work no matter what mode IE is running in:

if(document.getElementById('title')==document.activeElement)
