I have limited exposure to javascript so I need some basic help.

I am using the follow script for a drop down menu box:

<head>
<script language=JavaScript>
<!--
function Navigate() {
var number = NavSelect.selectedIndex;
location.href = NavSelect.options[number].value; }
// -->
</script>
</head>

Then within the body of the page:

<select name="NavSelect" onChange="Navigate(this.form)">
<option value="" SELECTED>Click to Navigate
<option value="http://governmenteducators.us/munoff/">Municipal Clerks
<option value="http://governmenteducators.us/munoff/">Finance Officers
<option value="http://governmenteducators.us/munoff/">Tax Collectors
<option value="http://governmenteducators.us/munoff/">Public Works Managers
<option value="http://governmenteducators.us/constcode/">Construction Code Officials
<option value="http://governmenteducators.us/constcode/">Technical Assistants
<option value="http://governmenteducators.us/constcode/">Multiple Dwelling Inspectors
</select>

The drop down box works fine in the latest MS IE broswer, but will not work in either Netscape or Mozilla.

What am I missing? Thanks

Oh, I reckon it's because you reference this.form without actually embedding it into a form.

What about this?

<select name="NavSelect" onChange="return ="Navigate(this);" size="1">

The other thing is. When you pass a reference from a form, you should also be getting it in the function as an argument.

function Navigate(f) //f is the NavSelect form's current object
{

var number = f.selectedIndex;
location.href = f.options[number].value;

return true;
}
</script>

Changing location.href works fine in Explorer on Mac, Explorer 5.5+ on Windows and Netscape 6.

If it still doesn't work for some reason in another browser,
try this:

<script type="text/javascript" language="javascript">

function Navigate(f){
var number = f.selectedIndex;
var url = f.options[number].value;
window.open(url,'_top'); //make sure you dont put spaces inside (url,'_top'), NN does not like it
return true;
}

</script>


Oh, I forgot to add, that you should check if javascript is enabled in browsers such as NN or Mozilla. If not, this navigation will not work at all.

NavSelect.selectedIndex

This is not a valid DOM reference. The reference should be

document.formname.NavSelect.selectedIndex

Since you don't include the form tags I don't know what your form name is.
