Show layer onClick or onSubmit

nrenfree · Jan 24, 2007

I have two layers on a page. One layer contains a form with a set of radio buttons. When I click a radio button, I want to submit the form which sends the value of the radio button clicked and SHOW another layer that has a dropdown menu on it that shows a subset of a database column depending on the radio button clicked.

Everything works swell as long as I have everything shown all the time. What I want is for the drop-down menu to be hidden when the page loads and then appear when a radio button is clicked.

If I put the "Show Layer" behavior on each radio button, I can see the drop-down for a moment and then it goes away. If I put the "Show Layer" behavior on the "OnSubmit" of the form, I don't see the other layer at all.

What simple thing have a I missed?

Thank you for your help,

Nancy

You should be able to use show hide layers to achieve this. Have a look at the code below in a browser.

Code:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
<style type="text/css">
<!--
#Layer1 {
	position:absolute;
	width:200px;
	height:115px;
	z-index:1;
	background-color: #FF0000;
	visibility: hidden;
}
#Layer2 {
	position:absolute;
	width:200px;
	height:115px;
	z-index:2;
	left: 234px;
	top: 94px;
	background-color: #0000FF;
	visibility: hidden;
}
-->
</style>
<script type="text/javascript">
<!--
function MM_reloadPage(init) {  //reloads the window if Nav4 resized
  if (init==true) with (navigator) {if ((appName=="Netscape")&&(parseInt(appVersion)==4)) {
    document.MM_pgW=innerWidth; document.MM_pgH=innerHeight; onresize=MM_reloadPage; }}
  else if (innerWidth!=document.MM_pgW || innerHeight!=document.MM_pgH) location.reload();
}
MM_reloadPage(true);

function MM_findObj(n, d) { //v4.01
  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);
  if(!x && d.getElementById) x=d.getElementById(n); return x;
}

function MM_showHideLayers() { //v6.0
  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>
<form name="form1" method="post" action="">

    <input name="radiobutton" type="radio" onClick="MM_showHideLayers('Layer1','','show','Layer2','','hide')" value="layer1">
</p>
  <p>
    <input name="radiobutton" type="radio" onClick="MM_showHideLayers('Layer1','','hide','Layer2','','show')" value="layer2">
</p>
  <div id="Layer1"></div>
  <div id="Layer2"></div>
  <p>&nbsp;</p>
</form>
</body>
