I found a cool sample that illustrates the handling. Take a look at this (the source code :-D) http://edgemaster.dev.openstreetmap.org/oldemo/10.htm

Your vector layer needs a server part two handle the persistence. The save strategy only triggers the write back.

/* from the sample source */
var scribble = new OpenLayers.Layer.Vector("Scribble", {
    protocol: new OpenLayers.Protocol.HTTP({
        url: "featureserver/featureserver.cgi/scribble",
        format: new OpenLayers.Format.GeoJSON()
    strategies: [new OpenLayers.Strategy.BBOX(), new OpenLayers.Strategy.Save({auto: true})],
    projection: wgs
  • hi, thank your replay firstly. I've tried whole day on this, current the source as in below: jsfiddle.net/7Mr7d/42 I can load data use protocol now, but still didn't try out how to save data, save function is triggered, but how to do next, any suggestion on this?

  • I know it can be implemented by sending a ajax request, but want to learn how to use openlayers

  • I'm not sure if I'm right but imo if you add the right URL to your vector layer it automatic writes the data back. But you need a related server part. For instance a wfs server or a script that handles the request server side. The post from rashad give you some sample components for that

What you are looking for is a WFS-T service. OpenLayers does support WFS, WFS-T and is based on ajax request because of javascript ion of OL. The steps are as follows:

Setup the following:

  1. PostgreSQL / PostGIS.
  2. WFS server - (Geoserver,MapServer,tinyOWS).
  3. WFS Client ofcourse, openlayers

tinyOWS is small and easy A full tutorial from start can be found here

  • actually I can place ajax codes in commit function to save data without WFS-T, just want to learn the way openlayers does
