list menu to change text field 1

mikemedia · Oct 25, 2007

I've done it before, but now I'm bumbling.
Need to change text field based on option selected in list menu.

What have I done wrong? Please, need quick answer!

<script language="JavaScript" type="text/javascript">
function whichTest() {
if(document.getElementById('rank').option.selected.value = "Private" || "PFC" || "LCpl" || "Cpl" || "Sgt" || "GS01" || "GS02" || "GS03" || "GS04" || "GS05" || "GS06" || "GS07" || "GS08")
{
document.getElementById('whichTest').value = "EmpTest";
} else {
document.getElementById('whichTest').value = "SupvTest";
}
}
</script>

comparison is == not =, and if you wanna do this comparison your going to have do something like

Code:

var rank = document.getElementById('rank').option.selected.value 
if(rank == "Private"||rank=="somethingelse"{
 do something
}

I would rather do something like

Code:

var rankreg = /Private|PFC|LCpl|Cpl|Sgt|GS[0][1-9]/;
rankreg.test(document.getElementById("rank").value);

What th' heck am I doin' wrong?!?

Revised script in order to keep it REAL SIMPLE. Still, Nada!

Code:

<head>
<script language="JavaScript" type="text/javascript">
function whichTest() {
var rank = document.form1.getElementById('rank').option.selected.value 
	if(rank == "Private")
	{
 		alert("OK!");
	} 
}  
</script>  
</head>
<body>
<form id="form1" name="form1" method="post" action="">
  <p>
    <select name="dropper" id="dropper" onChange="whichTest()">
      <option value="null" selected="selected"></option>
      <option value="you">you</option>
      <option value="me">me</option>
      <option value="them">them</option>
      <option value="Private">Private</option>
    </select>
  </p>
</form>
</body>
</html>

>var rank = document.form1.getElementById('rank').option.selected.value
[tt]var rank = document.form1.dropper.value;[/tt]

Or if you have some reminiscence of selected something and want to use it, it is this.

[tt]var rank = document.form1.dropper.options[document.form1.dropper.selectedIndex].value;[/tt]

But, it becomes clumsy.
