DOM 2 (question about CSS)
I am able to do this, to retrieve a value as a string:

Code:
 //(IE version)

document.styleSheets[0].rules.item(0).style.getPropertyValue('width');


This will give me a string, e.g. '100px'

But what I want is just the numeric value, i.e. 100, so that I can use it in a math formula.

How can I do this?

Thanks.

A simple
parseInt(thewholelineyoualreadyhave)
will do.

You could make it Mozilla-compatible as well:

var ss = document.styleSheets.item(0);
var rules = ss.cssRules || ss.rules;
var width = parseInt(rules.item(0).style.width);
