Small javascript to auto-adjust height of same class DIVs

We need a tiny Javascript that lets you find all divs with the same class name on a page and then automatically adjusts the height of all Divs to the height of the DIV with the largest height by setting a class name in a function. The divs could be anywhere on the page and not necessarily in a parent div. The script needs to update if the text size in the browser is increased or decreased. Using css with display:table etc will not work in this case. Needs to be cross browser compatible. Thanks. eg. function tag: equaldiv('columnset1') ## Deliverables html source: <div> <div> <div class="columnset1"><p>long text<p><p>long text<p><p>long text<p><p>long text<p><p>long text<p><div> <div class="columnset1"><p>long text<p><p>long text<p></div> <div class="columnset1"><p>long text<p><p>long text<p><p>long text<p></div> </div> <div> <div class="columnset1"><p>long text<p><p>long text<p><p>long text<p><p>long text<p><p>long text<p><p>long text<p><p>long text<p><div> <div class="columnset1"><p>long text<p><p>long text<p><p>long text<p><p>long text<p></div> <div class="columnset1"><p>long text<p></div> </div> </div> <div> <div> <div class="columnset1"><p>long text<p><p>long text<p><p>long text<p><p>long text<p><p>long text<p><p>long text<p><p>long text<p><div> <div class="columnset1"><p>long text<p><p>long text<p><p>long text<p><p>long text<p></div> <div class="columnset1"><p>long text<p></div> </div> </div> ## Platform JavaScript Cross browser compatible, Internet Explorer, FireFox, Opera, Netscape, Safari 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
