Please help: Zoom to Lat/Long not working

DorotheaKnigge — Mon, 02 Jul 2012 18:40:23 GMT

Hello,

I am developing a web application for managing collisions. Users will be able to enter new collision data. Collision data often comes with the "lats and longs" of where the incident occurred; therefore I would like to add a zoom to lat and long "Submit" button to the application. The problem is that clicking the "Submit" button zooms out not in like it should.
I'm new to Javascript API development and would sincerely appreciate help in getting this to work.

First, the submit function needs to be changed as:

          function submit()  {     Lat = parseFloat(document.getElementById("inputLat").value);     Lng = parseFloat(document.getElementById("inputLng").value);      var pt = new esri.geometry.Point(Lng,Lat);     map.centerAndZoom(pt, .5);  }

There is a NIM bug report for this issue. [NIM079613 The Map.centerAndZoom(mapPoint, levelOrFactor) function falsely zooms out on a Dynamic MapServiceLayer with version 2.6, 2.7, and 2.8; but the same code works well with version 2.5 and before.]

If you switch to JS API version 2.5, it works fine.
