Return to HTML screen/file position after refresh

Hi All,

I have a graph displayed above a detail table and have hyperlinks on the table column titles that will resort the data based. The table is displayed about 2/3 way down the screen. When I click the column titles, the screen refreshed to display graph and the sorted data but the form is reset to the top. Is there anyway to return to the position that the form was in before I clicked on the hyperlink. As it stands now, the user has to scroll down everytime they resort the data.

Thanks,

Norb

There are many different ways, have you tried using a window.scrollTo or window.scrollBy in the onLoad event of the body? If you are using HTML frames, you might have to change the syntax slightly.

window.scrollTo(x,y)
-- Used to scroll to a specified location

window.scrollBy(h,v)
-- Used to scroll the screen by a given number of pixels.

Evaluate what the user will do more - look at the report or look at the graph - if it's the report, put the report above the graph...

Hi Someusr,

I haven't tried the two methods that you suggested but honestly, wouldn't know how to add them to the code correctly.

Thanks,

Not exactly sure how you are generating your HTML code, but you can put the following code before the </BODY> tag (with <SCRIPT> and </SCRIPT> tags around it) or create an external JavaScript (js) file named whatever you want and put the following code in it:

var OrigOnLoad = document.body.onload;
document.body.onload = ScrollFx;
function ScrollFx()
{
  if (OrigOnLoad) OrigOnLoad ();
  window.scrollTo(0,300);
}

You will have to adjust the values in the scrollTo to fit your needs.

Here is a sample / test HTML file....

<HTML><HEAD><TITLE>ScrollTest</TITLE></HEAD>
<BODY>

Norb, your drilldown is regenerating the entire page, graph and all, yes?
if so, you're getting exactly what you're asking for.
Can you put the elements side by side?
Table left, graphic right.
That way, the user keeps on the table when clicking.
You know how to do side by side, yes?

-HTMLFORM BEGIN
<TABLE>
<TR>
<TD VALIGN=TOP>
!IBI.FIL.MYTAB;
</TD><TD VALIGN=TOP>
!IBI.FIL.MYGRAF;
</TD></TR>
</TABLE>
-HTMLFORM END

Norb,

Is your output format HTML? If so then place the two components in separate IFRAMEs so that when you refresh the data component to sort it, you only update the second IFRAME. Simple to do without having to resort to Javascript etc. which is still new to you.

As a reminder, the TARGET value on your drilldown would need to be the IFRAME name attribute.

i was thinking that, too, T, but wondering if the graf was related to the data in the table, then when the table changed, the graf should as well. Sounds like a perfect spot for wf's new flex feature.

Hi SomeUsr,

Thanks for the reply, I will have to copy the code and see what I can come up with. I'm still very green in the javascript/WebFocus area.

Hi Susannah,

Yep, my drilldown is regenerating the entire page using the technique that you detailed in your post. I did try putting the data side by side but didn't think it looked to good. Not quite sure where I'll go from here. I'll check out Tony's ideas about the separate iFrame as well. (iFrame reminds me of iPhone but I won't start that again - hee hee)

Thanks to both you and Tony,

Norb

Norb,

Start that subject off and it'll be your round at Summit - and I'm looking at the most expensive cocktail, reputed to be $1500 - called the Duvet Platinum Passion in New York, or maybe the Mai Tai in Northern Ireland.

Perhaps Gerry will have these at the cocktail reception? Then again maybe not
