How can I select several DIV-Objects using their ID

[Chris Turner]

Hello.
Okay, here's my problem:
I got several DIV's and all start with the same ID="contentDiv " and at the end they got a number.
For example, the php could generate following DIVs:
contentDiv2
contentDiv4
contentDiv23
contentDiv24
I just want to set all of these DIVs to:
div.style.displ ay = 'none';
but I have no idea how I could efficiently select them.
All my Ideas are way to complicated and cause a noticeable delay...
getElementsByNa me isn't possible because DIVs do not have the "name"-tag...
and I heard that getElementsByCl ass (/Name) doesn't work for IE...
Does anyone of you got a professional solution for this problem?

Thank you in advance.
Chris

give the divs a class and use a cross-browser implementation of getElementsByCl assName() (ex.)

Okay, this seems to be perfect for my needs.
Thank you very much.
