Need some help on a loop

**gszauer** · 01-10-2007, 08:33 PM

Code:

  <script language="Javascript" type="text/javascript">
  <!-- Hide from older browsers
  a0 = new array(
    new Array("title", "url"),
    new Array("title2", "url"),
    new Array("title3", "url")
  )
  function changeMenu (arrayName){
   selected =  document.mainDcument.categories.options[document.mainDcument.categories.selectedIndex].value
    if (selected != ""){
        selectedValue = parseInt(selected)
        document.mainDcument.playlist.options.length = 0
        for (i=0; i<=arrayName.length ; i++){
            document.mainDcument.playlist.options[i] = new Option(arrayName[i][0])
             // arrayName[i][0]
            //document.mainDcument.playlist.options[i].value = i
        }
    }
  }
  // end hiding script -->
    </script>

If i replace

Code:

 document.mainDcument.playlist.options[i] = new Option(arrayName[i][0])

with

Code:

 document.mainDcument.playlist.options[i] = new Option("Dummy")

The script works just fine, but otherwise it refuses to populate my other list...
Can anyone please help out?
I appriciate your time
Thanks

I would look into this...

a0 = new array();
a0[0]= new Array("title", "url");
a0[1]= new Array("title2", "url");
a0[2]= new Array("title3", "url");

tryed that it didn't work.
Also, to my knowlege in Javascript you do not need to end your lines with ;

If it helps, my full code is

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <title></title>
  <script language="Javascript" type="text/javascript">
  <!-- Hide from older browsers
  a0 = new array(
    new Array("title", "url"),
    new Array("title2", "url"),
    new Array("title3", "url")
  )
  function changeMenu (arrayName){
   selected =  document.mainDcument.categories.options[document.mainDcument.categories.selectedIndex].value
    if (selected != ""){
        selectedValue = parseInt(selected)
        document.mainDcument.playlist.options.length = 0
        for (i=0; i<=arrayName.length ; i++){
            document.mainDcument.playlist.options[i] = new Option(arrayName[i][0])
             // arrayName[i][0]
            //document.mainDcument.playlist.options[i].value = i
        }
    }
  }
  // end hiding script -->
    </script>
</head>
<body>
<form name="mainDcument" action="http://">
    <select name="categories" size="5" id="categories" onchange="changeMenu ('a0')">
         <option value="0">populate</option>
        <option value="1">populate</option>
        <option value="2">populate</option>
    </select>
    <select name="playlist" size="5" id="playlist" onChange="changeMenu ()">
         <option value="0">UnPopulated</option>
    </select>
</form>
</body>
</html>
