Javascript / jQuery正则表达式的“边界半径”值

Question

I'm using jQuery corner plugin for border-radius cross-browser support. This is my function:

if(!Modernizr.borderradius){ 
    var s = document.styleSheets;
    for(var i = 0; i<s.length;i++){ 
        var r = s[i].rules || s[i].cssRules;
        for(var x=0;x<r.length;x++) {
            var t = r[x].cssText || r[x].style.cssText;
            if(t.search("radius")>0) $(r[x].selectorText).corner();
        }
    }
}

Basically, i'm retrieving any element who has border-radius set.

I need a better regex, like this one:

border(-)?(top|bottom)?(-)?(left|right)?-radius:(.+?);

to detect any variation of border-radius and retrieve its value. Thanks a lot
