OpenLayers 2.7's WFS-T support does not support modification or deletes. This missing functionality will be fixed in your current code sometime before the 2.8 release (#1787), but it is recommended to use the WFS protocol for all access of this sort, which is already in trunk. http://openlayers.org/dev/examples/wfs-protocol-transactions.html > Definition of WFS > var cities = new OpenLayers.Layer.WFS( > "Cities", > "http://10.128.78.27:8080/geoserver/wfs";, > {typename: topp:tasmania_cities'}, > {featureNS: http://www.openplans.org/topp', > extractAttributes: true}); > cities.style = OpenLayers.Util.applyDefaults({strokeColor: "#0000ff"}, > OpenLayers.Feature.Vector.style["default"]); > > Defination of Add, Edit, Del, Save. > > function deleteFeature(geometry) > { > this.state = OpenLayers.State.DELETE; > this.layer.removeFeatures(geometry); > this.renderIntent = "select"; > } > > var drawPoint = new OpenLayers.Control.DrawFeature( > cities, OpenLayers.Handler.Point, > {displayClass: 'olControlAddFeaturePoint'}); > drawPoint.featureAdded = function(feature) { > feature.layer.eraseFeatures([feature]); > // cast to point > feature.geometry = new OpenLayers.Geometry.MultiPoint(feature.geometry); > feature.style.strokeColor = "#0000ff"; > feature.state = OpenLayers.State.INSERT; > feature.layer.drawFeature(feature); > } > > var edit = new OpenLayers.Control.ModifyFeature(cities, > {title: "Modify Feature", > displayClass: "olControlModifyFeature"}); > > var save = new OpenLayers.Control.Button( > {title: "Save Changes", > trigger: OpenLayers.Function.bind(cities.commit, cities), > displayClass: "olControlSaveFeatures"}); > > var del = new OpenLayers.Control.SelectFeature(cities, > {title: "Delete Feature", > onSelect: deleteFeature, > displayClass: "olControlDeleteFeature"}); > > > Kind Regards, > > Sunder Raj Abbai Naidoo > Specialist: Analyst Programmer > IT Consulting; Solution Delivery > +27 (0)12 470 1584 (Office) > +27 (0)12 470 1456 (Fax) > +27 (0)83 461 3397 (Mobile) > > > > . > _______________________________________________ > Dev mailing list > Dev@openlayers.org > http://openlayers.org/mailman/listinfo/dev -- Christopher Schmidt MetaCarta _______________________________________________ Dev mailing list Dev@openlayers.org http://openlayers.org/mailman/listinfo/dev
