Get style attributes from class?

Copy linkTweet thisAlerts:

I need to find out if a div has the style of disply:none;. I can’t use obj.style.display because this attribute is being set in a class, not as an inline style. Is there anyway to get this info with javascript?

@ZeroKilledMar 13.2009 — use standard method [b]getComputedStyle[/b] and for msie browser use currentStyle object.
<i>
</i>if(getComputedStyle)
getComputedStyle([i]element[/i], null).display; // DOM compliant browser
else [i]element[/i].currentStyle.display; // for msie
// replace [i]element[/i] with an element node;

@rnd_meMar 14.2009 — if you know the class that causes it to hide, you can see if it or any parents have that class attrib...

here is dual browser self-mutation function that grab applied styles:
[CODE]
function getstyle(obj, cAttribute) {
if (obj.currentStyle) {
this.getstyle = function (obj, cAttribute) {return obj.currentStyle[cAttribute];};
} else {
this.getstyle = function (obj, cAttribute) {return document.defaultView.getComputedStyle(obj, null)[cAttribute];};
}
return getstyle(obj, cAttribute);
}[/CODE]
