Hello Experts,

I have a select:
<select id="myselect" onChange="parent.myfunction(selected value, selected option)">
<option value='abc'>123</option>
<option value='def'>456</option>
</select>

If the user selects 456. How do I pass 456 and the associated 'def' value.

Thanks
Dipen

Here's one way to do it:

<script>
function myfunction(thisSelect)
{
	alert('name: ' + thisSelect.options[thisSelect.selectedIndex].name)
	alert('value: ' + thisSelect.options[thisSelect.selectedIndex].value)
}
</script>

<select id="myselect" onChange="myfunction(this)">
<option name=123 value='abc'>123</option>
<option name=456 value='def'>456</option>
</select>

Hi jaqku
here is a sample code
<!DOCTYPE html>
<html>
<head>
  <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>

  
 <script>
	$(document).ready(function() { 
		$('#myselect').change(function(){
			var txt = $(this).find('option:selected').text();
			var val = $(this).find('option:selected').val();
			alert(txt + '  -- >  ' + val);
		});
	});

 </script>
</head>
<body style="font-size:62.5%;">

<select id="myselect" onChange="parent.myfunction(selected value, selected option)">
	<option value='abc'>123</option>
	<option value='def'>456</option>
</select>

</body>
</html>

With an improvement thanks to mhmr:I forgot about the "text" attribute.

<script>
function myfunction(thisSelect)
{
	alert('text: ' + thisSelect.options[thisSelect.selectedIndex].text)
	alert('value: ' + thisSelect.options[thisSelect.selectedIndex].value)
}
</script>

<select id="myselect" onChange="myfunction(this)">
<option value='abc'>123</option>
<option value='def'>456</option>
</select>
