[OpenLayers-Users] Automatic updation of OpenLayers code

[Robert Sanson]

You can write a function to refresh the layer. Something like:
 
function refreshLayer() {
for (key in map.layers) {
                var layerRef = map.layers[key];
                if (layerRef.name == "Points"){
                  layerRef.destroy();
                }
              }
//then your code for reloading the layer here, including re-adding to the map
map.addLayer(myPoints);
}
 
Regards,
 
Robert

Hi, 

  I have my map code in openlayers JS. My input data is in a text file and I
am able to render the points on the map. I have to give the user a right to
create a layer by entering the data in a form. Writing a program to insert
data into a text file is trivial. But I am stuck at how to include this
layers code in the JS programmatically so that after giving the layers
details in the form if the user reloads the page then the new layer should
be visible, Any solutions??
