How do I get the border-radius from an element using jQuery?

Question

I\'ve got a div, with the following HTML and CSS. In an attempt to make my Javascript code more robust, I\'m attempting to retrieve certain CSS attributes from the selected

I'm guessing it's not officially supported yet as it's a bit unpredictable... In Firefox using $("#somediv").css("-moz-border-radius", "20px"); will set the border radius fine, but trying to read it back via $("#somediv").css("-moz-border-radius"); returns an empty string... However, it appears that Firefox explodes the border radius into its component parts meaning $("#somediv").css("-moz-border-radius-topleft"); will work (obviously only returns one corner's settings though).

Edit:

As Tgr points out $('#foo').css('MozBorderRadius') will let you read it back generically in Firefox. And as Bradley Mountford points out in a comment below, it looks like you can read from Webkit using the component parts too (although only chrome seems to like border-top-left-radius, where as both Chrome & Safari handle -webkit-border-top-left-radius...

So summarising, you get the following (based on your 5px setting):

In Firefox:

$("#somediv").css("MozBorderRadius");             //"5px 5px 5px 5px"
$("pre").css("-moz-border-radius-topleft");       //"5px"

In Webkit (tested in Chrome & Safari):

$("pre").css("-webkit-border-top-left-radius");   //"5px 5px"
