Scripting form elements 1

[Arion23]

Hi all,

I apologise for asking what I'm sure is a very easy question to answer, but I am having a very "bad hair day"

I have a number of radio buttons and dropdown lists in a form, and I'm trying to find some simple code that will achieve the following effect:

If user makes a selection from dropdown A, Radio A becomes checked, if user makes a selection from dropdown B, then Radio B becomes checked.

Many thanks in advance...

Hi Arion23,

Put this script between the head:

<script language=&quot;JavaScript&quot;>
	function checkRadio(which) {
		document.form.radio[which].checked = true
	}
</script>

And this form in the body:

<form action=&quot;&quot; name=&quot;form&quot; method=&quot;post&quot;>
	<select name=&quot;dropa&quot; onChange=&quot;checkRadio(0)&quot;>
		<option selected>---</option>
		<option>line1</option>
		<option>line2</option>
	</select>
	<br>
	<select name=&quot;dropb&quot; onChange=&quot;checkRadio(1)&quot;>
		<option selected>---</option>
		<option>line1</option>
		<option>line2</option>
	</select>
	<br>
	<input type=&quot;radio&quot; name=&quot;radio&quot;>Radio A
	<br>
	<input type=&quot;radio&quot; name=&quot;radio&quot;>Radio B
</form>

This does the trick.

Hope it gets you started!
