JavaScript - Get value of SelectedIndex

How do I get the value of a SelectedIndex?

See below code

<script>
function toggleTextBox(){

var x = document.myform.hotOrderList.options;

if(x.[this.selectedIndex].value == 'Yes'){

document.myform.txtHotOrderName.style.display = '';
}
else{
document.myform.txtHotOrderName.style.display = 'none';
}
}
</script>

Regards,
Edmond

This code is copied straight from one of my projects, but should show you what you need to do:

Code:

		j = document.Premium.Title.length;
		for (i=0; i<j; i++) {
			if (document.Premium.Title[i].selected) var strTitle = document.Premium.Title[i].value;
		}

In order to determine which SELECT item is selected, you must iterate through the list and check the "selected" property

That's just not true.

You can use the "selectedIndex" property.

Code:

var s = document.getElementById("Title");
alert(s.options[s.selectedIndex].value);
