[mapguide-users] Select and zoom to feature in Mapguide+Fusion

[Chris Claydon]

Hi Alba,

Do you get any errors displayed when you run this?

Does the alert popup correctly with your map name?

If you add an alert to display the selectionXml, does it look valid too?

The instructions below refer to the most recent version of Fusion, so I can't guarantee that they're valid for the one you're using...

I don't think the Fusion map object has a SetSelectionXML method. Instead, you would want to call map.setSelection(selectionXml, false). The second parameter controls whether or not you want to zoom to the extents of the selection.

There is also no ZoomToView method in the current version. Instead, you should call var extent = map.getExtentFromPoint(feature.centerX, feature.centerY, scale); and then map.setExtents(extent);

Let me know if this works with your version.

Chris.

hi Traian,

You excuse me for this email, but I see that you have sent many posts, then
maybe you can help

I have the problem to select and to zoom objects on map

I use mgos 2.0.1 with IIS and fusion
I insert the function

<script language="javascript" >

In my procedure I insert

function GetParent()
{
    if(popup) {
        return opener;
    } else {
        return parent.parent;
    }
}


...
function Selezione_oggetto(){

var resultSelect = document.getElementById("resultSelect");
var k=0;
var valoreCercato=dati_ord[resultSelect.value];
while(valoreCercato!=dati[k]){
  k=k+1;
  }
            //alert(k);
            reqParams = "COMMAND=GETSELECTIONXML";
			reqParams += "&SESSION=" + encodeURIComponent(session);
            reqParams += "&MAPNAME=" + encodeURIComponent(mapName);
			reqParams += "&LAYERNAME=" + encodeURIComponent("Catastali");
			reqParams += "&IDLIST=" + results[k].idList.toJSONString();
            if (msie)
                reqHandler = new ActiveXObject("Microsoft.XMLHTTP");
            else
                reqHandler = new XMLHttpRequest();

            reqHandler.open("POST", "querycontroller.php", false);
            reqHandler.setRequestHeader("Content-Type",
"application/x-www-form-urlencoded");
			reqHandler.send(reqParams);
			selectionXml = reqHandler.responseText;
            alert(mapName);

// ?????????? problem----------------------

//parent.parent.mapFrame.SetSelectionXML(TrimString(selectionXml));// old
for mg 1.2

var map = GetParent().Fusion.getMapByName(mapName);  // ??????????

map.SetSelectionXML(selectionXml);// ??????????
}


function Zoom_oggetto()
{//alert("ZoomToFeature");
var resultSelect = document.getElementById("resultSelect");
var scaleInput = document.getElementById("scaleInput");
scale = scaleInput.value;
scale = (scale == 0) ? 10000 : scale;
scale = scale*1.0;
var k=0;
var valoreCercato=dati_ord[resultSelect.value];
while(valoreCercato!=dati[k]){
    k=k+1;
  }

feature = results[k];

// ?????????? problem----------------------
//parent.parent.mapFrame.ZoomToView(feature.centerX, feature.centerY, scale,
true);// ??????????

var map = GetParent().Fusion.getMapByName(mapName);// ??????????
map.ZoomToView(feature.centerX, feature.centerY, scale, true);// ??????????

}


</script>

all from example ..www\phpviewersample\query

but it does not work!

Can you help me, please?

Thank Alba
