Remarks

Use the document object to examine, modify, or add content to an HTML document and to process events within that document. In a Web page, the document object can be referenced through the document property of the window object or it can be referenced directly.

The document object is available at all times in the primary document, but it does not exist for the HTML Component (HTC) files used in lightweight Dynamic HTML (DHTML) behaviors. This is because lightweight behaviors can only be defined if they do not use a document object in the HTC file. As a result, lightweight behaviors run faster and more efficiently than normal behaviors. Lightweight DHTML behaviors can, however, access the document object of the primary document in the same way as normal DHTML behaviors.

The ondocumentready event notifies DHTML behaviors that the document object is available from the primary Web page containing the behavior. Once ondocumentready has fired, a behavior can begin to manipulate the primary document object.

It is possible for the script in a behavior to reference the document object in the HTC file or the primary document. When coding script in an HTC file, use element.document to refer to the document object in the primary document.

Examples

This example uses the document object to check for a document title and displays the title (if not null) in a message box.

if (document.title!="") alert("The title is " + document.title)

This example shows an event handler function that displays the current position of the mouse, relative to the upper-left corner of the document, in the browser's status window.

<HTML> <HEAD><TITLE>Report mouse moves</TITLE> <SCRIPT LANGUAGE="JScript"> function reportMove() { window.status = "X=" + window.event.x + " Y=" + window.event.y; } </SCRIPT> <BODY onmousemove="reportMove()"> <H1>Welcome!</H1> </BODY> </HTML>
