pass an object to an evt

DavidKearney1

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); });

                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);

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)
