pass an object to an evt

DavidKearney1 — Thu, 15 Aug 2013 11:56:33 GMT

Hi, we're occasional users of the JSAPI using an older API (2.1). We're trying to create a page which does 2 things, first using a mark point function, which gives us a pop up with a symbol for the point and it gets the coords for us (onClick).

function markpoint(evt)

We want to pass this through to an identify function to identify the map at these cords using function 'doIdentify(evt)'

We get the datagrid with no data, so it's not taking the marked point....

The text below is where it gets to: Anyone see any glaring errors?

function doIdentify(evt) {
            //map.graphics.clear();
            identifyParams.geometry = evt;
            identifyParams.mapExtent = map.extent;
            identifyTask.execute(identifyParams, function(idResults) {addToMap(idResults, evt); });

   dojo.connect(map.infoWindow, "onShow", function() {
                dijit.byId("tabs").resize();

            });

        dojo.connect(map, "onClick", markpoint);

         };

function markpoint(evt) {
        map.graphics.clear();
        var point = evt.mapPoint;
        var symbol = new esri.symbol.SimpleMarkerSymbol().setStyle(esri.symbol.SimpleMarkerSymbol.STYLE_POINT);
        var graphic = new esri.Graphic(point, symbol);
        var outSR = new esri.SpatialReference({ wkid: 27700});
        map.graphics.add(graphic);

        gsvc.project([ point ], outSR, function(projectedPoints) {
          pt = projectedPoints[0];
          graphic.setInfoTemplate(new esri.InfoTemplate("Coordinates",
            "<p> X: " + pt.x +
            "<br/> Y: " + pt.y +
            "</p>" +
            "<input type='button' value='Confirm Point' onClick='identifypoint(map);' />" +
            "<div id='latlong'></div>"));
          map.infoWindow
            .setTitle(graphic.getTitle())
            .setContent(graphic.getContent())
            .show(evt.screenPoint, map.getInfoWindowAnchor(evt.screenPoint));

Yes, that's they way I pass in the evt to a function

identifyTask.execute(identifyParams, function (results) { populateTC(results, evt); });

How are you building the datagrid? Does this thread give you any ideas?

And if you're going to post code, please wrap it in the

 block (the # button above)

Thanks Ken

Tried re-writing this but using a standard popup for the identify instead of datagrid, this time using the latest API.

Getting the same problem - so I posted this separately, apologies in advance, I didn't use the CODE button... I know for future though (using the forums's confusing me as much as the API.....)

Cheers
