I have a dropdown list. On Selection, it will request extent of selected property to database (PostgreSQL). I am using PHP for server-side processing.

At client-side on console log gives extent output result (variable res):

[74.3965356273929, 75.2484319931094, 35.6450698628058, 34.776235256942]

Also I am sure that coordinates are float and not string using parseFloat() function. later I am passing that variable to OpenLayers.Bounds.

    var extent = new OpenLayers.Bounds(res);

OpenLayers.Bounds gives following output:

OpenLayers.Bounds.OpenLayers.Class.initialize {left: 74.396535627393, bottom: 75.248431993109, right: 35.645069862806, top: 34.776235256942, left: null…}

Which is I guess correct. But Openlayers is not zooming to the provided extent and it is zooming to maximum zoom level at current map view only.

  • What projection is your map in? is it web Mercator(EPSG:3857)? Nov 18, 2013 at 11:52
  • its just a guess, but can you try to switch the order of the coordinates? like this: 34.776235256942, 74.3965356273929, 35.6450698628058, 75.2484319931094

The order of attributes when you create an OpenLayers.Bounds object, you have to order the arguments like this: minx, miny, maxx, maxy.

See the following example:


  • That is the answer. worked like charm...
