I'd like to create a drop-down menu, but for each selection, I'd like to call a specific javascript.. Sort of like

<html>
<head>
<!-- javascripts here -->

</head>
<body>
<form name="form" >
  <select name="select">
    <option>Select one</option>
    <option>run js1</option>
    <option>run js2</option>
  </select>
</form>
...

Note: it should not require a submit button, since only one item can be selected.

Thanks!

Sure, something like this;

<head>
<script language=javascript>

function JS1()

.... your code

end function

function JS2()

.... more of your code

end function

</head>
<body>

<form name="form" > 
  <select name="select">
    <option>Select one</option>
    <option value="javascript:JS1();">run js1</option>
    <option value="javascript:JS2();">run js2</option>
  </select>
</form>
</body>
</html>

Tried suggestion 1, as there would be more than 2 options, but something is still wrong.. perhaps its my formatting?
Using the Dreamweaver layer show/hide function as an example..


<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="JavaScript">
<!--
function MM_findObj(n, d) { //v3.0
  var p,i,x;  if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
  if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
  for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document); return x;
}

function MM_showHideLayers() { //v3.0
  var i,p,v,obj,args=MM_showHideLayers.arguments;
  for (i=0; i<(args.length-2); i+=3) if ((obj=MM_findObj(args[i]))!=null) { v=args[i+2];
    if (obj.style) { obj=obj.style; v=(v=='show')?'visible':(v='hide')?'hidden':v; }
    obj.visibility=v; }
}
//-->
</script>
</head>

<body bgcolor="#FFFFFF">
<p><a href="#" onMouseOver="MM_showHideLayers('Layer2','','hide','Layer1','','show')">open
  layer 1</a></p>
<p><a href="#" onMouseOver="MM_showHideLayers('Layer2','','show','Layer1','','hide')">layer
  2</a></p>
<div id="Layer2" style="position:absolute; width:200px; height:115px; z-index:2; left: 266px; top: 76px; visibility: hidden">gbdgfbgdgvdgf</div>
<div id="Layer1" style="position:absolute; width:200px; height:115px; z-index:1; visibility: hidden">gnfhhgbfbg</div>
<form name="form" >
  <select name="select">
    <option>Select one</option>
    <option value="javascript:MM_showHideLayers('Layer2','','hide','Layer1','','show');">run js1</option>
    <option value="javascript:MM_showHideLayers('Layer2','','show','Layer1','','hide');">run js2</option>
  </select>
</form>

Our Dev teams are like yours. They’re continually cranking out code for new features/bugs fixes, testing, deploying, testing some more, responding to production monitoring events and more. It’s complex. So, we thought you’d like to see what’s working for us.

my comment was just an addition to the first one... you are not limited to just two... you just need to extend you if-then-else or use a switch statement.
