Input Toggle

Two different ways to toggle inputs (not fully tested), just ideas. I would recommend using "display" instead of "visibility" to hide/show inputs.

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> New Document </TITLE>

<script language="javascript">
	function switchInputs(){
		sVal = document.f1.Comm_DEV.options[document.f1.Comm_DEV.selectedIndex].value; 

		eArr = document.getElementsByTagName('tr');
		for(var x = 0; x < eArr.length; x++){
			idVal = eArr[x].id.split("-");

			if(idVal[0] == 'toggle'){
				if(idVal[1] == sVal){
					eval("document.getElementById('toggle-" + sVal + "').style.visibility='visible'");
				} else {
					eArr[x].style.visibility = 'hidden';
				}
			}
		}		
	}

	function morph(){
		sVal = document.f1.Comm_DEV.options[document.f1.Comm_DEV.selectedIndex].value;

		if(sVal == 'CE'){
			document.getElementById('morph-input').innerHTML='<input type="text" name="cell_phone">';
			document.getElementById('morph-td').innerHTML='Cell Phone:';
			document.getElementById('morph-tr').style.visibility='visible';
		} else if(sVal == 'PE'){
			document.getElementById('morph-input').innerHTML='<input type="text" name="pager_device">';
			document.getElementById('morph-td').innerHTML='Pager Device:';
			document.getElementById('morph-tr').style.visibility='visible';
		} else if(sVal == 'EM'){
			document.getElementById('morph-input').innerHTML='<input type="text" name="email_address">';
			document.getElementById('morph-td').innerHTML='Email Address:';
			document.getElementById('morph-tr').style.visibility='visible';
		}
	}
</script>
</HEAD>

<BODY>
<form name="f1">
<table>
<tr>
<td>Comm_DEV </td>
<td>
<SELECT name="Comm_DEV" size="1" onChange="morph();">
<OPTION Value="">Please Select</OPTION>
<OPTION Value="CE">CELL_Phone</OPTION>
<OPTION Value="EM">email_Address Only</OPTION>
<OPTION Value="PE">pager_device</OPTION>
</select></td>
</tr>
<tr id="toggle-CE" style="visibility:hidden;">
	<td>Cell Phone:</td>
	<td><input type="text" name="cell_phone"></td>
</tr>
<tr id="toggle-EM" style="visibility:hidden;">
	<td>Email Address:</td>
	<td><input type="text" name="email_address"></td>
</tr>
<tr id="morph-tr" style="visibility:hidden;">
	<td id="morph-td"></td>
	<td id="morph-input"></td>
</tr>
</table>
</form>
</BODY>
</HTML>
