javascript position page

[bigbinc]

set scroll position in javascript.

Is there a way to do this without using document.locati on, example.

document.locati on = "#gohere"


<a name="gohere">

Re: javascript position page

just use an <a href> tag, no need for JS here

<a href="pagename. html#gohere">Li nk</a>

Re: javascript position page

In IE only, you can use the scrollIntoView method.

object.scrollIn toView()

You can also pass an argument to specify scrolling the element to the
top or bottom of the page. For more information, see ...

intoview.asp

Not ideal if you are publishing to the internet, but if it's an intranet
or controlled environment then you could use it.

Using a function taking the name of an anchor:
function pageXY( el)
{
var XY={x:0, y:0};
for( var node = el; node; node=node.offse tParent)
{ XY.x += node.offsetLeft ;
XY.y += node.offsetTop;
}
return XY;
}
function gotoName( name)
{
var anchors, anchor, XY;
anchors=documen t.anchors;
anchor=anchors[name];

if(!anchor) // IE sucks
{ for( var i = 0; i < anchors.length; ++i)
{ if(anchors[i].name==name)
{ anchor = anchors[i];
break;
}
}
}
if(!anchor)
{ if( document.getEle mentById)
anchor=document .getElementById (name);
else if( document.all) // untested
anchor=document .all[name];
}
if(anchor)
{ XY = pageXY(anchor);
window.scrollTo (XY.x, XY.y);
}
}

----

This contains some "paranoid" code in that it searches for an element
with the same id as the supplied name if it cannot find a matching
anchor, and makes no attempt to fix broken positioned offset chains as
may be encountered for anchors within tables using padding and borders,
or anchors within relatively positioned elements under MSIE.

Found in testing:
* IE 6 doesn't appear to implement document.anchor s as an HTMLCollection
and didn't return a named anchor property,
* As I understand it, document.getEle mentsByTagName( "A") should return a
nodeList without named lookup (part of the NamedNodeMap and
HTMLCollection interfaces). Not included in above code, Mozilla returned
an HTMLCollection, Opera 7 a "nodeList" with named lookup support and
IE6 some kind of index collection *with* named lookup.

For trivial comment, document.locati on was deprecated in favor of
window.location as far back as javascript 1.3, although all three
browsers tested seem to support it.
