Why always show the javascript class AutoSuggestControl is not defined?

Why always show AutoSuggestControl is not defined?

I have a js file defined the class AutoSuggestControl
function AutoSuggestControl(oTextbox) {
...........
}

And the index.html included this file and new the object at onfocus event.

<script type="text/javascript" src="autosuggest.js"></script>

<input type="text" id="name" onfocus="new AutoSuggestControl(this)" />

But when the textbox is onfocus, a javascript error shows AutoSuggestControl not defined.

When you use a tool such as Firebug [firefox] or fiddler [ie] do you see the file being requested? Is the file in the same directory as the file you are requesting? If you type

javascript:alert(typeof AutoSuggestControl);

into the address bar, does it say undefined?
