dear Johnny


  var lastSelectedFeature;

        var layer;

        function changeColor() {

            if (lastSelectedFeature.feature.id == "1")

            { lastSelectedFeature.feature.style.fillColor = "#F3AF20"; HideContextMenus(); }

            else {

                lastSelectedFeature.feature.style.fillColor = "#F12B20"; HideContextMenus();

            }

            layer.redraw();

        }



        function OnMapCreated(map) {

            layer = map.layers[1];

            map.layers[1].events.register('featureselected', map.layers[1], function (feature) {

                lastSelectedFeature = feature;

            });

        }



this "layer = map.layers[1];" is empty, but i"map.controls[0]" can get value,but I'm not sure get value is hightlightOverlayer.feature.


for example, after modifications for:



function OnMapCreated(map) {

            layer = map.controls[0];


                map.controls[0].events.register('featureselected', map.controls[0],function (feature) {

                lastSelectedFeature = feature;

            });

        }”



So for the "lastSelectedFeature = feature; " is not executed, so can not access to the selected Feature And when the right click menu can directly execute the changecolor function without executing the OnMapCreated function,so do not achieve the value of the lastSelectedFeature variable

 Hi Li



 


Would you please try the attached code, we made a little amendment to it, and now you should get the right HighlightOverlay.

Johnny
