Jumping in a frame using Javascript

[compassSoftware]

Hi,

I have two horizontal frames, one on top of the other.

The top frame is an image map of a street with property boundary's on
it.

The bottom frame is a table with each row of the table holds details
about a perticular property from the image map above.

The user clicks on the image map in the top frame and the corresponding
row in the table is highlighted in the bottom frame.

The table is very long and the rows continue below the visable canvas.

What i need is a way to jump to the row when it is highlighted so that
it displays no matter where in the table it is located.

Is it possible to jump in a frame or page using Javascript?

Here is the script I am using (just encase it helps someone get an idea
of what I mean).
"passdata" is the row id being passed in from the top frame. The row id
is used to find and highlight the corresponding row. What I really need
to do is to be able to use the row id to jump to a particular area of
the frame.

<script type="text/javascript">
<!--
var passdata = 1;
var oldpassdata = 1;

function Start() {
if(oldpassdata != passdata)
ShowPass();

id1 = setTimeout("Sta rt();", 100); // check value every .1 sec.
}

function ShowPass() {
highlightrow(pa ssdata);
oldpassdata = passdata;
}

function highlightrow(n) {
clearallrows()
document.getEle mentById(n).sty le.backgroundCo lor='#FFAABB';
}

function clearallrows(){
if (oldpassdata ==1)
oldpassdata = passdata;

document.getEle mentById(oldpas sdata).style.ba ckgroundColor=' #FFFFFF';

}
// -->
</script>

Use anchors. For each row, have an anchor close to it with a unique
name. You can have something like rown. So for each row, have an anchor
text near to it with name/id = rown. You can then jump to that row by
setting the location property of the bottom frame to the anchor name.
sthg like this in the highlightrow (n) function :
eval ("bottomFrameNa me.location='ro w" + n + "'");

Thanks

Thank you for that! That sounds like just what I need.

why the evil eval?

bottomFrameName .location='row' + n

wouldn't that work?

Yeah. Thanks

I used the bottomFrame2.lo caton='row' + n; and when i do I get
bottomFrame2 is undefined.
I then tried to place the document object before bottomFrame2 and I get

Document.bottom Frame2 is null or not an object error.

Any ideas?

I used document.locati on='row' + n and I get "The page cannot be found"
error message in the bottom frame.

you should use #rown. not just rown. using eval works for me fine.
