Javascript show one of two textareas based on radio button selection


I need to show two textareas, but hide one, and show the other based on radio button selection.

So there'll be two radio buttons, and depending on which is selected, it'll show one, or the other textarea.

I have a javascript function already in place which I send the element ID to, and it shows/hides (by display:block, display:none), I don't know if this could be used in some way for this?

Any help would be awesome.

Hello i-CONICA,

Try this for example :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script language="javascript">
	function changeTA(d) {
		var inputs = d.getElementsByTagName("input");
		for(var i=0; i<inputs.length;i++) {
			if( inputs[i].type == "radio") {
				var radio = inputs[i];
				document.getElementById(radio.value).style.display = radio.checked ? "block" : "none";
	<div class="myradio1">
        <input type="radio" id="radiob1" name="radiob" checked="checked" onchange="changeTA(this.parentNode)" value="ta1" />Show Textarea 1<br />
        <input type="radio" id="radiob2" name="radiob" onchange="changeTA(this.parentNode)" value="ta2"  />Show Textarea 2
<br />
<textarea id="ta1" cols="64" rows="16" style="display:block">I'm textarea1</textarea>
<textarea id="ta2" cols="64" rows="16" style="display:none">I'm textarea2</textarea>
