                               //                               初始化百度地图中心，并添加常用控件                                map.centerAndZoom(new BMap.Point(GetLongitudeOne,GetZeroLatitude),15);
                               //                               画出折线即轨迹

                                   er[i] = new BMap.Marker(point[i]);
                                   map.addOverlay(er[i]); // 将标注添加到地图中
                               }                               var polyline = new BMap.Polyline();
                                   polyline.setPath(point);
                                   polyline.setStrokeColor("blue");
                                   polyline.getStrokeWeight(6);
                                   polyline.setStrokeOpacity(0.5);
                                   map.addOverlay(polyline);
                                   map.enableKeyboard();   //启用键盘，默认关闭

                              var GetAllLongitude = new Array();
                               var GetaLat = new Array();
                               var GetLongitudeOne = 1.1;
                               var GetZeroLatitude = 1.1;             / /用来接收数据库返回的类型 $.ajax({                      //利用ajax 从后台输出数据到javascript
                                   async: false, 
                                   type: "POST",
                                   contentType: "application/json",
                                   url: "LocusQueries.aspx/lastlat",
                                   dataType: 'json',
                                   success: function lastlat1(result) {
                                        GetZeroLatitude = result.d;
                                   }
                               });
   }
//后台我用的webService.  前台javascript      .后台用的C#
