Given this code:
-----------------------------------------------------
<html>
<head>
<title></title>
<script type="text/javascript" src =
"/js/prototype.js"></script>
<script type="text/javascript">
function init() {
alert(document.viewport.getHeight());
}
Event.observe(window, ''load'', init);
</script>
</head>
<body>
</body>
</html>
--------------------------------------------------------
In FF the alert says 8, and in IE 6 & 7 I get 0. Isn''t this
supposed
to return the height of the viewable area?

Isn''t this supposed > to return the height of the viewable area?To get the full height of the window, including scrollable space, I''ve always used document.body.getDimensions().height or document.body.getHeight(). If you want just the height of the viewable area, you can use document.viewport.getDimensions().height or document.viewport.getHeight(). http://prototypejs.org/api/document/viewport document.body does not seem to be mentioned in the Prototype API docs, but it is just a regular Prototype extended element so all the methods that you can do on any other DOM element can also be done on document.body. -justin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

If I change init to:
function init() {
if (navigator.appName == "Microsoft Internet Explorer"){
alert(document.body.offsetHeight);
} else {
alert(window.innerHeight);
}
}
I do get the height of the viewport.
document.viewport.getHeight() seems to tell me the height of the
content within the viewport.

You are in a quirks mode. That''s why document.body acts as a document. Add a proper doctype and it should work as expected.
