在地图上添加自己想要的功能模块
具体代码如下
1 var map; 2 window.onload = function () { 3 var myOptions = { 4 mapControl: false, //关闭默认的控件 5 mapTypeId: sogou.maps.MapTypeId.ROADMAP 6 } 7 map = new sogou.maps.Map(document.getElementById("map_canvas"), myOptions); //初始化地图 8 9 10 var homeControlDiv = document.createElement(‘DIV‘); //创建 11 homeControlDiv.style.position = "absolute"; 12 homeControlDiv.style.left = "20px"; 13 homeControlDiv.style.top = "5px"; 14 15 var homeControl = new HomeControl(homeControlDiv, map); //获取控件 16 map.getContainer().appendChild(homeControlDiv); //将控件添加到地图上 17 18 19 } 20 function HomeControl(controlDiv, map) { 21 22 controlDiv.style.padding = ‘5px‘; 23 24 //测距功能 25 var goHomeText = document.createElement(‘DIV‘); 26 goHomeText.style.fontFamily = ‘Arial,sans-serif‘; 27 goHomeText.style.backgroundColor = ‘white‘; 28 goHomeText.style.cursor = ‘pointer‘; 29 goHomeText.style.borderStyle = ‘solid‘; 30 goHomeText.style.borderWidth = ‘1px‘; 31 goHomeText.style.borderColor = ‘black‘; 32 goHomeText.style.fontSize = ‘12px‘; 33 goHomeText.style.textAlign = ‘center‘; 34 goHomeText.style.float = ‘left‘; 35 goHomeText.style.width = "60px"; 36 goHomeText.innerHTML = ‘<b>测距</b>‘; 37 controlDiv.appendChild(goHomeText); 38 39 //获取坐标 40 var SetZbText = document.createElement(‘DIV‘); 41 SetZbText.style.fontFamily = ‘Arial,sans-serif‘; 42 SetZbText.style.backgroundColor = ‘white‘; 43 SetZbText.style.cursor = ‘pointer‘; 44 SetZbText.style.borderStyle = ‘solid‘; 45 SetZbText.style.borderWidth = ‘1px‘; 46 SetZbText.style.borderColor = ‘black‘; 47 SetZbText.style.fontSize = ‘12px‘; 48 SetZbText.style.textAlign = ‘center‘; 49 SetZbText.style.float = ‘left‘; 50 SetZbText.style.width = "60px"; 51 SetZbText.innerHTML = ‘<b>获取坐标</b>‘; 52 controlDiv.appendChild(SetZbText); 53 54 //清空多余描点 55 var setHomeText = document.createElement(‘DIV‘); 56 setHomeText.style.fontFamily = ‘Arial,sans-serif‘; 57 setHomeText.style.backgroundColor = ‘white‘; 58 setHomeText.style.cursor = ‘pointer‘; 59 setHomeText.style.borderStyle = ‘solid‘; 60 setHomeText.style.borderWidth = ‘1px‘; 61 setHomeText.style.borderColor = ‘black‘; 62 setHomeText.style.fontSize = ‘12px‘; 63 setHomeText.style.textAlign = ‘center‘; 64 setHomeText.style.float = ‘left‘; 65 setHomeText.style.width = "60px"; 66 setHomeText.innerHTML = ‘<b>清空</b>‘; 67 controlDiv.appendChild(setHomeText); 68 69 }

动态为地图添加描点（可后台管理）
1 var map; 2 var MapZBs,Listener; 3 var num; 4 //获取类的唯一示例 5 function getInstance(a) { 6 a.hasOwnProperty("_instance") || (a._instance = new a); 7 return a._instance 8 } 9 window.onload = function () { 10 var myOptions = { 11 mapControl: false, //关闭默认的控件 12 mapTypeId: sogou.maps.MapTypeId.ROADMAP 13 } 14 map = new sogou.maps.Map(document.getElementById("map_canvas"), myOptions); //初始化地图 15 16 17 Marks(); //动态添加描点 18 } 19 //动态添加描点 20 function Marks() { 21 //ajax动态调取后台数据 22 var marks; 23 $.ajax({ 24 type: "post", 25 contentType: "application/json", 26 url: "Index.aspx/GetMarks", 27 success: function (data) { 28 FxData(data.d); 29 } 30 }) 31 } 32 //描点内容分析 33 function FxData(Data) { 34 var array = Data.split(‘|‘); 35 var HtmlCon = ""; 36 for (var j = 0; j < array.length; j++) { 37 if (array[j].toString() != "") { 38 var Yarr = array[j].split(‘&‘); 39 var TypeImages; 40 switch (Yarr[4].toString()) { 41 case "1": TypeImages = "images/b1.png"; break; 42 case "2": TypeImages = "images/o1.png"; break; 43 case "3": TypeImages = "images/r1.png"; break; 44 case "4": TypeImages = "images/z1.png"; break; 45 } 46 HtmlCon += ‘<li id="mark‘ + (j + 1) + ‘" class=""><h3 class="dining" style="background: url(‘ + TypeImages + ‘) no-repeat;background-size: 30px 30px;">‘ + Yarr[2] + ‘</h3><div class="priceinfo2">‘ + Yarr[3] + ‘</div></li>‘; 47 } 48 } 49 document.getElementById(‘tmd_data‘).innerHTML = HtmlCon; 50 51 for (var i = 0; i < array.length; i++) { 52 if (array[i].toString() != "") { 53 var Yarr = array[i].split(‘&‘); 54 AddMark(Yarr[0], Yarr[1], Yarr[3], Yarr[2], Yarr[4], Yarr[5], i, i); 55 } 56 } 57 } 58 //生成描点和弹出层 59 function AddMark(location, location1,Con,Title,ImgType,Images,mark,num) { 60 var location = new sogou.maps.Point(location, location1); //描点位置 61 //var location = new sogou.maps.LatLng(location, location1); 62 var TypeImages = ""; 63 switch (ImgType) { 64 case "1": TypeImages = "images/b1.png"; break; 65 case "2": TypeImages = "images/o1.png"; break; 66 case "3": TypeImages = "images/r1.png"; break; 67 case "4": TypeImages = "images/z1.png"; break; 68 } 69 70 mark = new sogou.maps.Marker({ 71 position: location, 72 title: Title, 73 map: map, 74 icon: TypeImages, 75 isFixed:true//不允许被清除 76 }); 77 78 var contentString = ‘<div class="Tan"><div class="wpic"><img src="images/‘ + Images+ 79 ‘" /></div>‘ + 80 ‘<p>‘ + Con + ‘</p>‘ + 81 ‘</div>‘; 82 //创建窗体 83 var infowindow = new sogou.maps.InfoWindow({ 84 content: contentString 85 }); 86 var container = document.createElement(‘div‘); //创建div 87 container.innerHTML = contentString; 88 89 var tpn = new sogou.maps.ToolPanel(); 90 tpn.setPanel(container); 91 sogou.maps.event.addDomListener(mark, ‘click‘, function () { 92 infowindow.open(map, mark); 93 tpn.setPoint(this.getPosition());//搜索功能 94 tpn.setCallback(function (a) { infowindow.setContent(a, 1) }) 95 }); 96 }
ajax后台代码为
1 [WebMethod] 2 public static string GetMarks() 3 { 4 string str = ""; 5 DataTable dt = GetData(); 6 foreach (DataRow rows in dt.Rows) 7 { 8 str += rows["PointX"].ToString() + "&" + rows["PointY"].ToString() + "&" + rows["Company"].ToString() + "&" + rows["Explain"].ToString(); 9 str += "&" + rows["MarkType"].ToString() + "&" + rows["ComImage"].ToString() + "|"; 10 } 11 return str; 12 } 13 14 private static DataTable GetData() 15 { 16 DataTable dt = new DataTable(); 17 string sql = "select * from MapMark"; 18 SqlConnection cnn = new SqlConnection(SqlCon); 19 using (SqlCommand cmm = new SqlCommand(sql, cnn)) 20 { 21 using (SqlDataAdapter dapter = new SqlDataAdapter(cmm)) 22 { 23 dapter.Fill(dt); 24 } 25 } 26 return dt; 27 }
