Can't correctly pass value to function

[trapezechic]

I am new to javascript. Forgive me if this a dumb mistake...

I am trying to make a function that allows the user to click an image to set the radio button. I want to pass the value to the function from the onclick command to tell the function which radio button to set. It's not working. Here is my code:


<script>
function radioSelect(radioID) {
document.getElementById("radioID").checked = true;
}
</script>



<td><input name="room" type="radio" id="liveR" value="live" /><a href="#" onclick="radioSelect(liveR);"><img src="images/icon-live.jpg" width="50" height="60" /></a></td>

Welcome to WebmasterWorld!

document.getElementById("radioID")
should be:
document.getElementById(radioID)

Since radioID is the variable that you want to find. Otherwise, you'll be searching for the element with the literal ID value of "radioID".

Also for the opposite reason your call to radioSelect needs to be.

onclick="radioSelect('liveR');"

that is the literal value 'liveR' NOT a variable named liveR.

Yeah, good catch daveVk. :) I missed that.
