i am working with extjs and openlayers for trying some web application. now i want to create a coordinate bookmark which click than take this coordinate...
but first of all, it must create a layer in which name is "Bookmarks"..when you click on it ita take to the this coordinate...
how can add a layer in which name is "Bookmarks" and how can i go taking coordinate from map...
If I understand your question correct, you will need a vector layer to display the bookmarks:
var my_bookmark_layer = new OpenLayers.Layer.Vector(
"Bookmarks",
}, {
displayInLayerSwitcher: true
});
map.addLayer(my_bookmark_layer);
This will add an empty layer which You can use later on.
To get a coordinate from the map, see this example in the OpenLayers example folder. Then you will need to store the coordinate as a feature in the bookmark layer.
Hope it helps :)
