Question

Given this html element:

<input id="test" style = "outline-width: medium;" />

And this jQuery call:

console.log($('#test').css("outline-width"));

I see this in the console (IE 8):

“Unspecified error.”

jQuery 1.8.2 is included on the page (the version doesn’t seem to matter), but I don’t think it is a jQuery issue.

Try this fiddle out in IE8: http://jsfiddle.net/vAWB4/5/

Why does the call fail? It works fine in every other browser I’ve tried, including IE9 set to the IE8 browser mode.

Answer 1

IE8 will throw an error when you use "outline-width" unless you specify a DOCTYPE. Also there is the option of using the <meta> tag to force it to run in IE8 Standard Mode.
