[mapguide-users] RE: Fusion javascript (phpviewersample)

[Chris Claydon]

One more thing to try...

Defining the Fusion variable outside of the functions, by adding:

var Fusion = GetFusionWindow().Fusion;

just above the line:

var mapWidgetId = 'Map';

This should hopefully define the Fusion variable in the correct scope so that it can be picked up by Fusion.Tool.Canvas.prototype.getMap at line 172. It should also allow you to remove the individual var Fusion = ... lines from all the functions.

Chris.

Effectively, I try to launch the script in a new window. According to your remarks, I have changed in MapGuideViewerApi.js, the var "Fusion = window.top.Fusion" by" var Fusion = GetFusionWindow().Fusion" and I have added the function "GetFusionWindow()", unfornutely the same errors are observed:
Fusion is not defined
MapGuideViewerApi.js()        MapGuideViewerApi.js (line172)
Fusion.Tool.Canvas.prototype.getMap = function()

Fusion is undefined
Refresh()     MapGuideViewerApi.js (line 33)
OnApplyThemeReadyStateChange()

Looking at MapGuideViewerApi.js, it tries to reference Fusion using: var Fusion = window.top.Fusion.

This *should* work provided that the script is running in the task pane, and that the top level window contains the Fusion template. If you're running the template in a frame, or if you launch the script in a popup window, it would probably fail.

You could try something like this to provide a more robust means of locating Fusion... Please let me know if this helps!

var Fusion = GetFusionWindow().Fusion;

function GetFusionWindow() {
    var curWindow = window;
    while(!curWindow.Fusion)
    {
        if(curWindow.parent && curWindow != curWindow.parent)
        {
            curWindow = curWindow.parent;
        }
        else if(curWindow.opener)
        {
            curWindow = curWindow.opener;
        }
        else
        {
            break;
        }
    }
    return curWindow;
}

Subject: [mapguide-users] Fusion javascript (phpviewersample)

Hi,

I have migrated different applications ('theme layer' and 'query') onto fusion. The following lines of the javascript code encounter errors:
? parent.parent.Refresh();
? parent.parent.mapFrame.ZoomToView(feature.centerX, feature.centerY, scale, true);
? parent.parent.mapFrame.SetSelectionXML(TrimString(selectionXml));

For the "theme layer" application, I have referenced the "MapGuideViewerApi.js" in the script and I have changed the "parent.parent.Refresh();" by "Refresh()"  without success.
Errors referenced in firebug:
? Fusion is not defined
MapGuideViewerApi.js()        MapGuideViewerApi.js (line172)
Fusion.Tool.Canvas.prototype.getMap = function()

? Fusion is undefined
Refresh()     MapGuideViewerApi.js (line 33)
OnApplyThemeReadyStateChange()

For the "query" application, I have no solution.

Could you help me to resolve these problems?

Thanks,

Arnaud De Groof
