Hi

Am I rude if I say that your requirement is stupid ? Anyway, this works in Mozillas, Opera, Safari and Explorer.
Code: 
<html>
<head>
<script type="text/javascript">
var al=undefined
window.onload=function() {
  al=document.getElementsByTagName('a')
  for (var i=0;i<al.length;i++) al[i].onkeydown=go
}
function go(e)
{
  e=e?e:window.event
  var key=e.keyCode!=undefined?e.keyCode:e.which
  var obj=e.target!=undefined?e.target:e.srcElement
  if (!al || !key || !obj) return
  if (key!=38 && key!=40) return
  var dir=key==38?-1:1
  var pos=-1
  for (var i=0;i<al.length;i++) if (al[i]==obj) pos=i
  if (pos==-1) return
  al[(pos+al.length+dir)%al.length].focus()
}
</script>
</head>
<body>
<a href="test41_1.html">test41_1</a>
<br><a href="test41_2.html">test 41_2</a>
<br><a href="test41_3.html">test 41_3</a>
<br><a href="test41_4.html">test 41_4</a>
<br><a href="test41_5.html">test 41_5</a>
</body>
</html>
By the way, please learn more about HTML. Preferably before going forward to JavaScript.

test41_1.2
test41_1.3
test41_2
test41_2.1
test41_2.2
test41_2.3
test41_3
test41_3.1
test41_4
test41_5
test41_5.1
test41_5.2
test41_5.3

then
when i wl b at child say test41_5.2,
by LEFT key,it should directly come at test41_5.
and vice-versa at Right key.

can u please help?

Hi

[ul]
[li]Put the links into an unordered list.[/li]
[li]When right arrow is pressed, check if the node has a list item child, if has then focus it.[/li]
[li]When left arrow is pressed, check if the node has a list item parent, if has then focus it.[/li]
[/ul]

yes i got that already
but
how to find that
if the node has a list item child,
if the node has a list item parent?

thats the main question...

Hi

First of all, all those were answered before.

The DOM ( Document Object Model ) describes the structure and the ways to parse the structure of a document.

See the [tt]childNodes[/tt] and [tt]parentNode[/tt] properties of the elements. For simplicity you may want to use [tt]getElementsByTagName()[/tt] instead of [tt]childNodes[/tt], but the [tt]parentNode[/tt] you will have to use recursively.

if i use
x.parentNode
in the same javascript,then also its not giving me the parent node?
then
what is th possible way to implement?

Hi

[tt]parentNode[/tt] will give you the element's parent. But as I wrote, you will have to use it recursively. For example in the below sample you can see that the [tt]a[/tt] "test41_5.2"'s parent is the [tt]li[/tt], who's parent is the [tt]ul[/tt].
Code: 
<ul>
[gray]...[/gray]
  <li><a href="test41_5">test41_5</a>
  <ul>
    <li><a href="test41_5.2">test41_5.2</a></li>
    [gray]...[/gray]
  </ul>
  </li>
[gray]...[/gray]
</ul>
