I'm hoping document.viewport.getDimensions() can be improved.
At the moment I'm using a patched version in <a href='http://
www.nickstakenburg.com/projects/prototip'>Prototip</a> to keep
tooltips within the viewport, as it works better then the method from
trunk. Mootools uses a similar approach.
To point out the issues in the current function I've added unit tests.
They show that resizing an element { position: absolute; top: 0; left:
0; } to the viewport causes change in document properties. Those
properties should not be affected.
When resizing and showing overlay layers for example (lightbox), this
will add extra scrollbars in browsers where those document properties
are affected. The unit test I've added will run this example as a
test.
Patch and Unit test: <a href='http://dev.rubyonrails.org/ticket/
10148'>http://dev.rubyonrails.org/ticket/10148</a>
Thanks for checking it out,
Nick
