Help with matching HTML elements with increasing digits

Copy linkTweet thisAlerts:
May 13.2005

OK I have a script that works fine but I want the script to work on a number of similar elements on the same page. The elements are divs with IDs of ‘container1’, ‘container2’, ‘container3’ etc etc

So in the script is this line:

[code=html]document.getElementById(container[n]);[/code]

so it needs to be able to identify each container and their only difference is the last digit.

I’m pretty poor at writing new Javascript and don’t know it very well but I thought it could be done using regular expressions? I’ve learnt this area of js, but not too well coz I can’t get it to work. Which is annoying as hell coz I know this is soooooooooooo easy. 😡

Help please ?

@CharlesMay 13.2005 — You the one that started the whole "n" thing. I prefer "i".<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

@richiebmanauthorMay 14.2005 — Thanks for replying again Charles. I had already tried using loops but the rest of the script gets a bit complicated and creates more problems. I'm sure there is a way around it but I have decided to design the pages differently so that it doesn't require what I was first asking for. And it is actually a better design. Suppose sometimes problems make you think a little differently and come up with better solutions :rolleyes: .

Any hoo thanks and no I wasn't the one who started the whole "n" thing. But I have just worked out what the "i" stands for. I'm hoping "integer". I was going with "number" ? .

document.getElementById('container'+$i).DOWHATEVERHERE;
}
