I've been trying to get this working for a few days now but with no luck.

The code is:

<script type="text/javascript">
/* This script and many more are available free online at
The JavaScript Source!! http://javascript.internet.com
Created by: Alan Gruskoff | http://www.performantsystems.com/ */

function anyCheck(form) {
var total = 0;
var max = form.ckbox.length;
for (var idx = 0; idx < max; idx++) {
if (eval("document.playlist.ckbox[" + idx + "].checked") == true) {
    total += 1;
   }
}
al*rt("You selected " + total + " boxes.");
}
</script>
<form name="playlist" method="post">
    1<input type="checkbox" name="ckbox" /> <br />
    2<input type="checkbox" name="ckbox" /> <br />
    3<input type="checkbox" name="ckbox" /> <br />
    4<input type="checkbox" name="ckbox" /> <br />
    5<input type="checkbox" name="ckbox" /> <br />
    6<input type="checkbox" name="ckbox" /> <br />
    7<input type="checkbox" name="ckbox" /> <br />
    8<input type="checkbox" name="ckbox" /> <br />
    9<input type="checkbox" name="ckbox" />
    <p><input type="button" onClick="anyCheck(this.form)" value="Count Checkboxes" /></p>
</form>

Of course change '*' to 'e' at the end of the javascript as DNN forums don't like the Al*rt word!

It works fine just as itself in a small html file... but when used in a DNN website I just can't get it working.  I am new to using Javascript too so this is just a step to learning and understanding a bit more (though I am working towards performing a task).

I've tried separating the javascript from the form - using it in the module header, page header and also by linking it to an external js file with the code from these spots too - all failing to work.

What am I doing wrong and what do I need to do to get this working?

Thanks

Hi mamlin

Thanks for the quick reply.

Were you meaning to use:

<div name="playlist" method="post">
  ...
</div>

This is what I tried but had no luck.

I hadn't realised DNN automatically puts pages in a form as I'm only just starting to work with this sort of thing.

Cheers

Oh, if you're still new to javascript then be aware that it is case-sensitive (or else you'll quickly become a very frustrated JS coder...)
