passing form element name through a function

[MJB3K]

Hi, i have a problem passing a form element name through a function to act upon it. I dont know why it is not working.

The problem is that the function isn't picking up the form element that is being passed through.

The PHP outputs the correct name

<input type="checkbox" name="group1_<?php echo $name; ?>" value="<?php echo $pts; ?>" onclick="javascript:addPoints('group1_<?php echo $name; ?>', 'group1total',this.value);" />

function addPoints([COLOR=red]cb[/color], gr, pts){
	
	var curPts = parseInt(document.getElementById(gr).innerHTML);
	
	var cbname = document.memlist.cb;

	alert(cbname);
	
	

	// see if checkbox is checked or not for addition / subtraction
	
	if(document.memlist.[COLOR=red]cb[/color].checked == true){
			alert("yh");
			var newTot = curPts +  parseInt(pts);
	}else{
			alert("na");
			var newTot = curPts -  parseInt(pts);
	}
	
document.getElementById("group1total").innerHTML = newTot;
}

any ideas on how to make it work?

Why not show us what is actually being output by the PHP? Right now we have no idea.

That aside, you'd probably need to change this:

document.memlist.cb.checked

to this:

document.memlist[cb].checked

Hope this helps,

There are multiple ways to access properties on an object (or keyed items in a map, etc)... It's quite handy, though, as you can put a loop around it, etc.
