getting the e parameter from inline javascript

I want to insert an onkeydown directly as an attribute of an input tag.

problem is that i can't figure out a way to pass the event parameter?

(I know t开发者_如何学编程hat if we use addEventHandler and stuff like that we can pass the events parameter but in this case i'm restricted to just directly modifying the attribute of an element tag.

I also cannot insert any arbitrary <script > tags

<input type="text" onkeydown="alert(event.keyCode)" />

That should work fine in W3C compliant browsers. The event object is created automatically (although I'm not sure if it will work in IE).
