check checkbox onChange of another field

Copy linkTweet thisAlerts:
Mar 02.2011

I have a form that is basically a table from my database. I have checkboxes on the left and only those checked get updated on submit. I’m trying to make an function that is called with an onChange event that will check the box if any of the fields in that row are altered. The id of the checkbox is checkeds[i] where “i” is the row number. The function is firing, but the box isn’t getting checked. Any ideas?

[CODE]function checkBox(row)
{
var checkedId = ‘checkeds[‘ + row + ‘]’;
document.getElementById(checkId).checked=true;
}[/CODE]

@WolfShadeMar 02.2011 — function checkBox(row)

{

var [color=red]checkedId[/color] = 'checkeds[' + row + ']';

document.getElementById([color=red]checkId[/color]).checked=true;

}

As of right now, this is the only discrepancy that I can see.

@marcdd2authorMar 02.2011 — Thanks, but that was just an accidental cut.

The field code for the first row is:

[CODE]<input type="hidden" name="checkeds[0]" id="checkeds[0]" value="0">
<input type="checkbox" name="checkeds[0]" id="checkeds[0]" value="1" />[/CODE]

Does the hidden field effect it? I guess there is no reason to give that the same id.

[CODE]<input type="hidden" name="checkeds[0]" id="checkeds[0]" value="0">
<input type="checkbox" name="checkeds[0]" id="checkeds[0]" value="1" />[/CODE][/QUOTE]Names can be duplicated, but all IDs in a document must be unique.

Success!
