Just wondering if there is a script for scrolling to any verticle position onmousedown (without using links)...

In other words, if the mouse is depressed somewhere down a page, the scrollbar will move to become even with that position.


I did some searching, but found nothing remotely close, so I'm thinkin' not.

it's possible.

there's a JS method to get the cursor position
and there's a JS method to scroll the window

just put in your body tag the onMouseDown event handler then call your function that calculates the cursor position and then scrolls.

only probems i see for you are, scrolling if the page isn't at the dead top. because mouse postion is based on the viewable window not the page as a whole.

i may work on this just for kicks, let me know if you need more help.

anyone else?

<script language="JavaScript" type="text/javascript">
function scrollIt(e) {
evnt = event;
y = window.evnt.y;
self.scrollTo(0,y*6.8)
}
</script>


ok you can call it any way that you want, just place the event in the body tag.

For example.
<body onMousemove="scrollIt()">

[edit:] To get around the viewable area problem I just multiplied by 6.8, I came to that number by simply trial and error.

I am using @ 1024x768 so possibly you should chuck in a res check which will multiply the y coord accordingly.

That's perfect; thank you both for the lesson.

I found it to work best using "onclick", by the way... as
with "onmousedown", the scrollbar was dysfunctional.
