在任务栏显示地理坐标

function OnPageLoad() {

...

map.AttachEvent("oninit", MapInit());

map.Init();

}

 function MapInit() {

 //在任务栏显示地理坐标

  ShowMapCoord();  

}

 function ShowMapCoord() {

   var action = new ShowMapCoordAction();

   map.SetAction(action);

 }

function ShowMapCoordAction() {

    this.type = "SuperMap.IS.MapCoordAction";

    this.Init = function(mapControl) {

    this.mapControl = mapControl;

    if (_ygPos.browser == "ie") 

     { mapControl.container.style.cursor = _scriptLocation + "../images/cur_PointQuery.cur"; }

    else 

     { mapControl.workLayer.style.cursor = "url(images/cur_PointQuery.cur),auto"; };

   };

     this.Destroy = function() { this.mapControl = null; };

     this.OnClick = function(e) { };

     this.OnDblClick = function(e) { };

     this.OnMouseMove = function(e) { window.status = "当前坐标 X=" + e.mapCoord.x + "  Y=" + e.mapCoord.y };

     this.OnMouseDown = function(e) { };

     this.OnMouseUp = function(e) { };

     this.OnContextMenu = function(e) { };

     this.GetJSON = function() { return _ActionToJSON(this.type, []); }

}

注意：要想让任务栏一直都能显示出坐标来，包括在放大、缩小的时候，那么需要在放大缩小的OnMouseMove事件中都添加上{ window.status = "当前坐标 X=" + e.mapCoord.x + "  Y=" + e.mapCoord.y }
