In the following code, i am attempting to perform the methods listed in the VALUES of the select part of the form on the click of a button. here is the code of the whole page. by the way, all of the methods listed have no errors, and i linked to them instead of showing them on the age to lessen confusion.

code:

<html>

<head>

<script src="scripts.js"></script>

<title> Javscript </title>

<script language="Javascript">



function changeit() {



for (var i=0; i<3; i++) {

if(document.f.ones.options[i].selected) {

document.f.ones.options[i].value) } }





}

</script>

</head>



<body>



<form name="f">

<textarea name="source" cols="50" rows="10"></TEXTAREA>

<select name="ones" value="sillyc" size="5" MULTIPLE>

<option value="trans()">1337 speak<option value="reversef()">Reverse<option value="allcaps(0)">All caps</select>

<input type="button" value="display results" name="go" class="gobutton" onclick="javascript:changeit()"></form>



</body>

</html>

Please help me troubleshoot.

I can see a lot of issues with that code. What seems to be the problem that you're having?

if I understand you right, I think that this little demo should do the trick for you - modify away to your hearts content

code:

<script language="javascript">

function fDoStuff()

{

	var objSelecter = document.getElementById("tester");

	var intSelectedIndex = objSelecter.selectedIndex;

	var strFunctionToExecute = objSelecter.options[intSelectedIndex].value;



	eval(strFunctionToExecute);

}



function test(intOption)

{

	alert(intOption);

}



</script>



<select id="tester" onChange="fDoStuff()">

<option value="test(1)">test1</option>

<option value="test(2)">test2</option>

<option value="test(3)">test3</option>

</select>
