Pass checkbox array to a function

[Nutthick]

I have a checkbox array that I need to pass to a function, but I'm having problems. My html for the array is as follows:

<input name="chkRpt[]" type="checkbox" id="rptTue" value="2" />
<input name="chkRpt[]" type="checkbox" id="rptWed" value="3" />
<input name="chkRpt[]" type="checkbox" id="rptWed" value="3" />

etc...

When the user clicks 'Go' I need to pass the array to a function. I'm using modal windows and this is the only way I can get data out. My onclick code is as follows:

onclick="sendAndClose(this.form.chkRpt)"

and my sendAndClose function is as follows:

function sendAndCloseRepeat(var1)
{
	window.dialogArguments.var1 = var1;
	window.returnValue=true;
	window.close();
}

The problem is I keep getting an error

Error: 'test.var1.0' is null or not an object

So somewhere I'm loosing my array, or maybe I didn't have it in the first place. Can anyone please tell me what I'm doing wrong?

Thanks

"this.form.chkRpt" is not an object - becuase you have no element nanmes "chkRpt". You have elements named "chkRpt[]" - which is an illegal name, because the [ and ] characters are invalid, and should not be used when naming elements.

I suggest renaming your elements to conform to the correct naming standard (even if it means giving all checkboxes different names), and rework the rest of your code around that.

Hope this helps,

I'd guess this was written with PHP. If you look at the PHP help page:

http://www.php.net/manual/en/faq.html.php#faq.html.select-multiple

you'll find a way around this. However, you should really learn how to write HTML correctly with PHP to interact easily with Javascript.

Thanks for the help. I've taken the long way round and given each checkbox an individual name. It's not very elegant, but it works.
