Please help me ... ;)

Use the onscroll event. It's not part of any standards, but should be reasonably well supported.

I test this code in Mozilla... -
<script type="text/javascript">
-
var golbal_var = 0;
-
function test(){
-
alert('');
-
document.getElementById('text_id').value = ++golbal_var;
-
}
-
</script>
-
</head>
-
-
<body onScroll=test()>
-
<input type='text' id='text_id'/>
-
<div style='width:2000px;height:2000px'/>

For Mozilla compatibility, see MDC.

Hey Acoder.....
A typical problem appears ...
It's - alert(document.body.scrollLeft+'\t'+document.body.scrollTop);
always showing value 0 ..no matter which scroll bars scrolled ....
What's wrong with it ..
Which browser? A quick test in Firefox works.

I am having this HTML code ..... -
<body onLoad = _test()>
-
<input type='text' id='text_id'/>
-
<div style='width:2000px;height:2000px' id='div_id'>
-
</div>
-
</body>
-
And this is my JavaScript code .. -
function test(){
-
alert(document.body.scrollLeft+'\t'+document.body.scrollTop);
-
}
-
function _test(){
-
window.onscroll = test;
-
}
-
When horizontal or vertical scroll bars gets scrolled then the both of the values come 0 ...... in Mozilla and in IE both ..
What's wrong with it .... ?
Again, your code works too in FF, at least. Have you got anything else on the page?

How strange ..i am getting an alert box with two values ..and both are 0 .....
believe me :(
I tested with this version of your code:
[html]<html>
<head>
<script>
function test(){
alert(document.body.scrollLeft+'\t'+document.body. scrollTop);
}
function _test(){
window.onscroll = test;
}
</script>
</head>
<body onload = '_test()'>
<input type='text' id='text_id'>
<div style='width:2000px;height:2000px' id='div_id'>
</div>
</body>
</html>[/html]Works in Firefox 3.0.3

But mine was Firefox 2.
Whatever it is ...i just wanted to know ..is there any way to position an element at the right most of the page ..... that means according to the position of the scroll bars ...could you guide me to do this ....?
Please ... ;)
Use "position: fixed" - a simple solution. Set the right property to 0 for it to be fixed to the right side of the window.
Note that position: fixed is not supported in IE 6, but you can make it work using the fix described here.

No no ..... if i scroll down or up ..or scroll horizontally ..at every situation the element should be at the rightmost corner of the page ..i think now u got my point ... ;)
That's why i tried to track the scroll event ... :)
Then you didn't understand what position: fixed does. That's exactly what you need.
See this modified example: - <html>
-
<head>
-
<style type="text/css">
-
#text_id {
-
position:fixed;
-
top:0px;
-
right:0px;
-
}
-
</style>
-
</head>
-
-
<body>
-
<input type='text' id='text_id'/>
-
<div style='width:2000px;height:2000px' id='div_id'>
-
</div>
-
</body>
-
</html>
I tested this code ..in IE 6 ..but it's not running ... -

-
}
-
</style>
-
</head>
-
<body>
-
<input type='text' class='text_id'/>
-
<div style='width:2000px;height:2000px' id='div_id'>
-
</div>
-
</body>
-
</html>

Where i am wrong ... :(
Sorry sorry .... i didn't read out your previous post ... ;)
I also tested it in Mozilla ...it's not working ....
IE 6 doesn't support position:fixed as I mentioned earlier. Use the fix that's described on the page I linked to earlier - Making Internet Explorer use position:fixed;
I'm not sure why it's not working for you in Firefox. It has done for a number of versions. Does the example in that link work?
