Populating an <INPUT> area dynamically

Sep 28, 2006, 05:04 PM

I have a listbox which presents data by means of PHP.
The PHP code also draws data from related record fields.

Once the PHP is done the following source code becomes available:

Code:

var emps = [
['American Studies','AMST'],['Anglican Studies','ANGL'],['Anthropology','ANTH']
];

These, ( Please Choose One, American Studies, Anglican Studies...),
appear as options in a listbox. Based upon the user's choice, the tied data should appear in a <input> box for editting.
This is where the problem comes into play. Running into a problem with the related data appearing in an <INPUT> box.

Page Source code:

Code:

<HTML><HEAD>
	<script type="text/javascript">
		var gebi = function(ELID){
			return document.getElementById(ELID);	}
		var emps = [
		['American Studies','AMST'],['Anglican Studies','ANGL'],['Anthropology','ANTH']
		];
		function updateDisplay(){
			var i = parseInt(this.value);
			gebi('deptspan').firstChild.nodeValue = (i>-1)?emps[i][1]:'';	}
		function init(){
			var s = document.forms['empviewer'].elements['emplist'];
			for (var i = 0; i < emps.length-1; i++){
				s.options[s.options.length] = new Option(emps[i][0],i);	}
			s.onchange = updateDisplay;	}
		window.onload = init;

	</script>
</HEAD>
<body topmargin="0" marginheight="0">
<FORM name="empviewer">
<div id="emptitle" style="position: absolute; width: 550px; left: 235px; top: 90px; z-index:5">
<table>
<tr bgcolor='#E0E0E0'>
	<td><select name="emplist" style='background-color: lightyellow'>
<option value="-1">Select a Dept </option>
</select></td></tr>
</table>
</form>
<label>&nbsp;MajorCode:&nbsp;</label>
<span id="deptspan">&nbsp;</span>
</div>
</body>
</html>
