================================== Element Behaviors - Ad Banner ================================== Last Updated: Aug.01,2000 SUMMARY ======== Element behaviors are a new technology in Microsoft® Internet Explorer 5.5. They allow Web authors to encapsulate reusable functionality inside an HTML component (HTC) file. A lightweight HTC--an HTC with less memory overhead that doesn't come with its own document--allows users to create lightweight components and reuse them many times on the same page. DETAILS ======== In the demo, the script that implements the "my:addbanner" custom tags is encapsulated in a separate file. The sample renders any HTML content inside of it in the top right position by default. By specifying values for the "bannerfromTop" and "bannerfromRight" properties on the behavior the banner can be made to render at a different position than the default position which is to the top right most corner of the page. The behaviors re-positions the content inside it when the page is either resized or scrolled. In order to allow the scrolling and resize events be notified of the behavior, attach the onresize and onscroll functions on the body of the HTML Page to call the behaviors relocate public method. In the page, additional functionality, (footerClick() function), is added to show and hide the floating advertisement. This is optional and can be removed to have the advertisement always floating. USAGE ====== Use of this behavior requires some basic declarations: - "Xmlns" declaration inside the HTML tag. - Import declaration with the appropriate namespace, as specified in the xmlns declaration and the path to the Adbanner.htc file. - The custom tags themselves should be included in the body of the HTML page, Content. - Required -- the onresize and onscroll event handlers on the Primary Document BODY Element with the event handlers calling the Behaviors relocate public method. - Optional -- bannerfromTop and bannerfromRight properties on the behavior specifying the position the content inside the behavior should render.
