Event Object Properties

Although event handlers in the DHTML Object Model do not receive parameters directly, a handler can query the event object for the following event properties.

Available Properties

clientY	Sets or retrieves the y-coordinate of the mouse pointer's position relative to the client area of the window, excluding window decorations and scroll bars.
offsetX	Sets or retrieves the x-coordinate of the mouse pointer's position relative to the object firing the event.

screenX	Sets or retrieves the x-coordinate of the mouse pointer's position relative to the user's screen.
screenY	Sets or retrieves the y-coordinate of the mouse pointer's position relative to the user's screen.
srcElement	Sets or retrieves the object that fired the event.

Remarks

If Asynchronous JavaScript and XML (AJAX) Connection Services are disabled, this event is not raised. (These services are enabled by default.)

Example

The following example sets an event handler that responds to both ononline and onoffline events using the type property of the event object.

function reportConnectionEvent(e)
{
    if (!e) e = window.event;
    
    if ('online' == e.type) {
        alert( 'The browser is ONLINE.' );
    }
    else if ('offline' == e.type) {
        alert( 'The browser is OFFLINE.' );
    }
    else {
        alert( 'Unexpected event: ' + e.type );
    }
}
window.onload = function() {
    document.body.ononline = reportConnectionEvent;
    document.body.onoffline = reportConnectionEvent;
}
