How to get Map corner latlong using open layer.??

Question

How to get Map corner latlong using open layer.??? i had tried with map.getBounds() method but it shows error like "map.getBounds is not a function"

so kindly reply for this error or any example.

here i had use OpenLayers.js

Answer 1

getBounds() only works for OpenLayers 2. Since it is failing for you I assume that you are using OpenLayers 3.

For OpenLayers 3 you have to look at the map extent by calling map.getView().calculateExtent() according to these similar questions:

Answer 2

Above Both function not working.

below is the my code, please correct it.

=====================================

<html> <head> <title>OpenLayers Demo</title> <style type="text/css"> html, body, #basicMap { width: 100%; height: 100%; margin: 0; } </style>

<script src="http://www.openlayers.org/api/OpenLayers.js" type="text/javascript"></script>

<script type="text/javascript">
    function init() {
        var marker_layer = new OpenLayers.Layer.Markers("Markers");

        map = new OpenLayers.Map("basicMap");
        var mapnik = new OpenLayers.Layer.OSM();
        var fromProjection = new OpenLayers.Projection("EPSG:4326");   // Transform from WGS 1984
        var toProjection = new OpenLayers.Projection("EPSG:900913"); // to Spherical Mercator Projection

        var position1 = new OpenLayers.LonLat(78.9629, 20.5937).transform(fromProjection, toProjection);
        var position2 = new OpenLayers.LonLat(79.2629, 20.9937).transform(fromProjection, toProjection);
        var zoom = 8;

        map.addLayer(mapnik);
        map.setCenter(position1, zoom);

    }
</script>

<script type="text/javascript">
    function GetData() {
        debugger;

        //var bounds = map.getBounds();       //Error : map.getBounds is not a function

        //var vv1 = map.getView().calculateExtent();  //Error : map.getView is not a function
    }
</script>

</head> <body onload="init();"> <input id="Button1" type="button" value="Click Here" onclick="GetData();"/>

</body> </html>
