zoom not zooming to mouse location

jaykapalczynski — Fri, 20 Jun 2014 19:30:22 GMT

I have this app...when I scroll zoom it does not zoom to where my mouse pointer is...its not bad in this jsfiddle but in my app its far worse...check the website below...and scroll / zoom in watch how it pushes to the right

Any thoughts?

Click the MAP button to bring up map

2 other questions:
1. Can I convert the XY to Lat Long after I click the map to populate the text boxes with XY?
2. Is there a better way to do this than using identifyParams?

Map is still zooming to the right ???? Dont know why

Think I got my XY Coordinate corrected with this

var normalizedVal = webMercatorUtils.xyToLngLat(XCoord, YCoord);
alert(normalizedVal);

Although the translated Coordinates put me in the Atlantic Ocean
JS App is returning -8036423.598 4246950.54
Translated with webMercatorUtils i get -72.192421 and 35.6089

Should be around -77 and 37

Dont know if there is a better way to capture XY coordinates and populate input boxes

Adding these lines seems to fix the Fiddle

    function DragDrop() {         //alert("IN DragDrop");         domUtils.toggle(dom.byId("divSplashScreenContainer"));         app.map.resize();         app.map.reposition();     }

These should be called after the map DIV has been repositioned and resized.

As for your other question, you can use getLatitude and getLongitude methods on a Point. See this thread

Is that getting the center of the map? I am trying to get the XY of a map click

It's just an example of different ways to get the latitude and longitude from a point. That thread used the example of the map's center, but a point is a point.
