Hi,

Does anyone have javascript to reference a button on an HTML parameter page from inside a report that is running in an iframe that is using WEBVIEWER to display?

What I've tried:
top.document.getElementId("button1")
window.document.getElementId("button1")
parent.document.getElementId("button1")
document.frames.iframe1.report.document.getElementId("button1")
top.frames.iframe1.document.getElementId("button1")

All with no success.
Ideas?
TIA

gregv,
Have you tried viewing the rendered HTML output for the button in question??

This may be a stupid question, but why are you wanting to reference a button from inside a report?

First of all it's not "getElementId", it's "getElementById".

Nice catch Francis...that should do it...

There's
"opener.document...", "parent.opener.document...",
"self.opener.document...",
"window.opener..."

and even "window.opener.parent.parent.frames"

...

I've used 'em all.

Thanks all for your suggestions. No joy.

PBrightwell: the reason I want to access a button on the html parameter page from the report is to re-enable the Run button after the user clicks it (I disable it onclick) and the report is displayed. That way they can't click it twice. This should work if i can just get a reference back to the top.document.

Has anyone used a hidden popup window for communication purposes?

Thanks.

Is its 'id'-attribute really 'button1', or is that perhaps the value of its 'name'-attribute (a common mistake)?
Is the 'button1' id unique in the page?

Is that button inside a frame by itself, perchance?
If so, you'll have to figure out how both documents (the WEBVIEWER frame document and the report frame document) fit in the top document hierarchy. Firefox+FireBug addon can be helpful there, as can some other tools.

If the button is in a frame, you could use something like:

top.document.getElementById('id of WEBVIEWER frame').getElementById('button1');

Since the report is using WEBVIEWER, it apparently creates an iframe on its own so, if you're already using an outer iframe, to access any element in the HTML parameter form you may need to access the report's parent's parent document node

Bah! Code speaks better than words:

DEFINE FILE CAR
SHOWME/A500 WITH CAR = '<input type="button" value="Show" onclick="' ||
                          'var x=parent.parent.document.getElementById(''runButton''); ' ||
                          'if(x) { x.value=''Again!'';}' ||
                       '">';
END
TABLE FILE CAR
PRINT 
     CAR.ORIGIN.COUNTRY
     CAR.COMP.CAR
     CAR.CARREC.MODEL
     CAR.BODY.BODYTYPE
     CAR.BODY.SEATS
WHERE CAR.ORIGIN.COUNTRY EQ '&PCOUNTRY.(FIND CAR.ORIGIN.COUNTRY,CAR.ORIGIN.COUNTRY IN car).Country.';
ON TABLE SUBFOOT
"<SHOWME"
ON TABLE SET PAGE-NUM NOLEAD 
ON TABLE NOTOTAL
ON TABLE PCHOLD FORMAT HTML
ON TABLE SET WEBVIEWER ON
ON TABLE SET WEBVIEWTARG OFF
ON TABLE SET HTMLCSS ON
ON TABLE SET STYLE *
     INCLUDE = endeflt,
$
ENDSTYLE
END

Due to lazyness, I'm relying on auto-prompting as produced in my 7.7.03 environment which auto-magically:

- Creates a basic form with a Country drop-down list and "Run" button (id="runButton")
- Creates an iframe to display the report upon clicking "Run"

From within the WEBVIEWER report, I can reference parent.parent.document.getElementbyId('runButton') and do whatever I want (or can). The sample code changes it's value/caption from "Run" to "Again!" but of course you have more serious needs

Hope this helps.
