The Internet Explorer Event Model: The Event Object - Doc JavaScript
The Event Object
Internet Explorer 4.0x's event
object is similar to the one in Navigator 4.0x. However, there are many differences between the two implementations.
The event
object in Internet Explorer 4.0x is available only during an event. Therefore, you can only refer to it in event handler scripts and event processing functions. The event
object is governed by the window
object, so its formal syntax is window.event
. The preceding window
specification is not necessary in any version of JavaScript, so it may be omitted.
The event
object represents the state of the event that is associated with the object at a given time, such as the element where the event occurred and the location of the mouse cursor.
The following example displays the current position of the mouse cursor (with respect to the browser window) in the status bar:
<SCRIPT LANGUAGE="JavaScript">
<!--
function displayLocation() {
var str = "";
str += "X=" + window.event.clientX;
str += ", ";
str += "Y=" + window.event.clientY;
window.status = str; // display in status bar
}
document.onmousemove = displayLocation;
// -->
</SCRIPT>
If you're using Internet Explorer 4.0x, you've probably already noticed the running numbers in the status bar. We'll discuss the cross-browser version for this script and others in our next column, covering the "cross-browser event model."
