I'm trying to find the selectedindex of the option which is selected by the user, but the following code show undefined whenever change occurs

<html>
<body>

<form>
<select id="ddlCar" name="cars" onchange="alert( String( document.getElementById( 'ddlCar' ).selectedindex ) );">
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="fiat" selected="selected">Fiat</option>
<option value="audi">Audi</option>
</select>
</form>

</body>
</html>

You just have to capitalize the 'i' to

.selectedIndex

Subtile but important.

You may use the this self reference to simplify the code

onchange="alert((this.selectedIndex).toString())"
