How to get my javascript results to display

[forum_amnesiac]

I have written some simple HTML code to enable selection from an 'auto' populated SELECT box. This is created in javascript and works fine.

I have another javascript function which selects from an array all the results that match the selection.

I would now like to display the results from that function to the side of the SELECT box.

I have tried various things without success so I am asking if there is a way to achieve this, and if so, how.

Here is my HTML

<form name="selectcategory">
  <table border="0" width="100%">
    <tr>
      <td>
        <select id='catSelect' name='category>
        </select>
      </td>
      <script type="text/javascript">populatecat(); </script>
      <td>
       <script>populateItems()</script>
       </td>
     </tr>
  </table>
</form>

I have put the function populateItems() in the place where I would like it to appear, the question is, how do I do this.

This is the javascript for the populateItems function

function populateItems() {
  	var cat = document.getElementById('catSelect').value;
	if (cat != ''){
		var itemLineArray = item.split("|");  // Split into lines
		for (var loop = 0; loop < itemLineArray.length; loop++) {
			lineArray = itemLineArray[loop].split(":");
			catCode  = TrimString(lineArray[0]);
			itemName    = TrimString(lineArray[1]);
			if (cat == catCode && catCode != '' ) {
				document.write(itemName+'<br>'); 
			}
		}
	}
}
