Help Capturing an onkeyup event

[Trent]

Hi. I know the basic way to assign event handlers:

<input onKeyUp="proces sEvent(event)" />

But how do I assign a function to the onKeyUp event in *javascript*
that can access the event object?

// get inputElement
alert("Some java script code");
inputElement.on keyup = ????;

I know how to assign generic functions. This works:

inputElement.on keyup = function() { alert("hello"); };

But how in the world do I assign a function that captures the "event"
object? I want something like:

inputElement.on keyup = function(event) { processEvent(ev ent) };

But that doesn't work right. Any ideas?

That last attempt should work with Mozilla/Netscape however the problem
is that IE has a global variable window.event that your event parameter
shadows so you need
inputElement.on keyup = function (evt) {
if (!evt) {
evt = window.event;
}
// now use evt e.g.
alert(evt.keyCo de);
};

No. You must decide if you want to use HTML

<!-- attribute name case does not matter, no trailing / -->
<iNpUt onKeyUp="proces sEvent(event)">

or XHTML

<!-- element and attribute names must be lowercased,
trailing / (empty content model) -->
<input onkeyup="proces sEvent(event)"/>

Does it work well finally? Today I need to implement the onkeyup event
but I found it doesn't work consistently. usually, the first few stroke
does not trigger the event, till I switch to another field and back to
this field. Then, the event can be fired for every keystroke. Any
idea?
