百度地图之多点步行路径连线问题
最近项目需要结合用到百度地图,需求是在地图实现多个点步行连线问题;因为百度有提供两点之间的步行路径图,以及沿线的坐标点信息;初步设想是首先把各个点的步行路径画出来,然后得到这条线路的坐标信息集合,然后通过百度地图的另外一个做直线接口重新把完整线路绘画出来;
如果你对百度地图的API知识不是很了解,可以查看http://developer.51cto.com/art/201110/298662.htm,里面有比较详细的介绍;
百度地图API开发者地址:http://developer.baidu.com/map/jshome.htm
一:通过结合下面两个百度实例来实现我们所要求的功能;
1:两点间步行实例:http://developer.baidu.com/map/jsdemo.htm#i6_1
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> body, html,#allmap {width: 100%;height: 100%;overflow: hidden;margin:0;} </style> <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=您的密钥"></script> <title>步行导航检索</title> </head> <body> <div id="allmap"></div> </body> </html> <script type="text/javascript"> var map = new BMap.Map("allmap"); map.centerAndZoom(new BMap.Point(116.404, 39.915), 11); var walking = new BMap.WalkingRoute(map, {renderOptions:{map: map, autoViewport: true}}); walking.search("天坛公园", "故宫"); </script>
2:折线实例:http://developer.baidu.com/map/jsdemo.htm#c1_5
<head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <style type="text/css"> body, html,#allmap {width: 100%;height: 100%;overflow: hidden;margin:0;} </style> <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=您的密钥"></script> <title>折线</title> </head> <body> <div id="allmap"></div> </body> </html> <script type="text/javascript"> var map = new BMap.Map("allmap"); var point = new BMap.Point(116.404, 39.915); map.centerAndZoom(point, 15); var polyline = new BMap.Polyline([ new BMap.Point(116.399, 39.910), new BMap.Point(116.405, 39.920), new BMap.Point(116.425, 39.900) ], {strokeColor:"blue", strokeWeight:6, strokeOpacity:0.5}); map.addOverlay(polyline); </script>
二:多点步行路径连线实例（完整的代码如下，都有相应说明,实例定义三个点）

左边是使用步行接口显示的三点连线地图,两点间都会标识起点跟终点,所以要是有多点地图上就会出现很为起点、终点的标志；右边这张是通过修改以后的地图；

上面实例中会存在一个问题,因为如果我们存在有多点情况下会进行for循环把每两个点的路线画出来,并得到这种路线的坐标集合;不过因为获取坐标集合百度地图API是通过回调函数实现;这边不得不面对一个FOR循环里包含回调方法,导致获得坐标集合顺序会出现问题;会出现如下图那样,有些点之间错乱,图在多出一些直接;

结合上面出现的问题对相应代码进行调整:
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <title></title> <script src="Scripts/jquery-1.8.2.js"></script> <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=nLpN5iKztxIWsPqgwsyrruUG"></script> <script type="text/javascript"> $(function () { $("#btn_Show").click(function () { showMap(); }); }); var chartData = []; function showMap() { var startSce = $("#<%=tb_Start.ClientID%>").val(); var EndSce = $("#<%=tb_End.ClientID%>").val(); var viaArray = $("#<%=tb_via.ClientID%>").val(); $.ajax({ type: "get", data: { startSce: startSce, viaArray: viaArray, EndSce: EndSce }, datatype: "json", url: "Handler1.ashx", async: false, success: function (userInfo) { var abc = $.parseJSON(userInfo); $.each(abc, function (item, value) { chartData.push(new BMap.Point(value.lan, value.yan)); }) for (var i = 0; i < chartData.length-1; i++) { var startPoint = chartData[i]; var endPoint = chartData[i + 1]; showPath(startPoint, endPoint); } $.each(abc, function (item, value) { var firstPoint = new BMap.Point(value.lan, value.yan); var m1 = new BMap.Marker(firstPoint); maps.addOverlay(m1); var lab1 = new BMap.Label(item+1, { position: firstPoint }); maps.addOverlay(lab1); }); } }); } function showPath(startPoint, EndPoint) { var walking = new BMap.WalkingRoute(map, { renderOptions: { map: map, autoViewport: true } }); walking.search(startPoint, EndPoint); walking.setSearchCompleteCallback(function (rs) { var abc = rs; var pts = walking.getResults().getPlan(0).getRoute(0).getPath(); maps.addOverlay(new BMap.Polyline(pts, { strokeColor: "green", strokeWeight: 2, strokeOpacity: 1 })); }); } </script> </head> <body> <form id="form1" runat="server"> 起点:<asp:TextBox ID="tb_Start" runat="server"></asp:TextBox> 途经点(以"|"进行分隔):<asp:TextBox ID="tb_via" runat="server" Width="295px"></asp:TextBox> 终点:<asp:TextBox ID="tb_End" runat="server"></asp:TextBox> <asp:Button ID="Button1" runat="server" Text="确认" OnClick="Button1_Click" /><br /><br /> 结果显示: <asp:Label ID="lb_message" runat="server"></asp:Label> </form> <br /> <br /> <input id="btn_Show" type="button" value="显示步行路线" /> 步行路径图: <div id="allmap" style=" height:900px; width:1000px"> </div> <br /> <br /> 修改后的路径图: <div id="r-result" style=" height:500px; width:900px"> </div> </body> </html> <script type="text/javascript"> var map = new BMap.Map("allmap"); map.centerAndZoom(new BMap.Point(118.075367, 24.44583), 15); map.addControl(new BMap.ScaleControl()); map.addControl(new BMap.NavigationControl()); var maps = new BMap.Map("r-result"); maps.centerAndZoom(new BMap.Point(118.075367, 24.44583), 15); maps.addControl(new BMap.ScaleControl()); maps.addControl(new BMap.NavigationControl()); </script>
主要是这里要注意(在回调过程中直接把直线画出来,不用再去获取两点间的坐标集合再去画线):
var pts = walking.getResults().getPlan(0).getRoute(0).getPath(); maps.addOverlay(new BMap.Polyline(pts, { strokeColor: "green", strokeWeight: 2, strokeOpacity: 1 }));
效果图如下：

上面修改后的图片可以对文字跟气泡进行再处理效果如下：
主要修改JS代码如下：
$.each(abc, function (item, value) { var firstPoint = new BMap.Point(value.lan, value.yan); //var startIcon = new BMap.Icon("ic_map_location.png", new BMap.Size(45, 45)); //var m1 = new BMap.Marker(firstPoint, { icon: startIcon, offset: new BMap.Size(-8, -15) }); var m1 = new BMap.Marker(firstPoint); maps.addOverlay(m1); var lab1 = new BMap.Label(item + 1, { position: firstPoint, offset: new BMap.Size(-10, -25) }); lab1.setStyle({ color: "#fff", fontSize: "16px", backgroundColor: "0.05", border: "0", fontWeight: "bold" }); maps.addOverlay(lab1); });

针对上面第二种是没有把线路坐标集合保存到数据库中,这样会出现每次页面加载都去百度那边进行获得坐标集合,针对这种情况进行修改,虽然FOR回调函数会出现错乱的问题,但这边可以加个标识让它显示出每一段集合是所属顺序,然后再进行合并出正确集合点;
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <title></title> <script src="Scripts/jquery-1.8.2.js"></script> <script type="text/javascript" src="http://api.map.baidu.com/api?v=2.0&ak=nLpN5iKztxIWsPqgwsyrruUG"></script> <script type="text/javascript"> $(function () { $("#btn_Show").click(function () { showMap(); }); }); var chartData = []; function showMap() { var startSce = $("#<%=tb_Start.ClientID%>").val(); var EndSce = $("#<%=tb_End.ClientID%>").val(); var viaArray = $("#<%=tb_via.ClientID%>").val(); $.ajax({ type: "get", data: { startSce: startSce, viaArray: encodeURI(viaArray), EndSce: EndSce }, datatype: "json", url: "Handler1.ashx", async: false, success: function (userInfo) { var abc = $.parseJSON(userInfo); $.each(abc, function (item, value) { chartData.push(new BMap.Point(value.lan, value.yan)); }) for (var i = 0; i < chartData.length - 1; i++) { var startPoint = chartData[i]; var endPoint = chartData[i + 1]; showPath(startPoint, endPoint,i); } } }); } function showPath(startPoint, EndPoint,PointIndex) { var walking = new BMap.WalkingRoute(map, { renderOptions: { map: map, autoViewport: true } }); walking.search(startPoint, EndPoint); walking.setSearchCompleteCallback(function (rs) { var pts = walking.getResults().getPlan(0).getRoute(0).getPath(); var ptsJson = JSON.stringify(pts); $.ajax({ type: "post", data: { SpointArray: ptsJson, PointIndex: PointIndex }, datatype: "json", url: "Handler3.ashx", async: false, success: function (userInfo) { } }); }); } </script>
Handler3代码如下:
using Newtonsoft.Json; namespace WebApplication1 { /// <summary> /// Handler3 的摘要说明 /// </summary> public class Handler3 : IHttpHandler { public void ProcessRequest(HttpContext context) { string start = context.Request["SpointArray"]; string PointIndex = context.Request["PointIndex"]; List<ResultList> list = JsonConvert.DeserializeObject<List<ResultList>>(start); List<ResultList> newList = new List<ResultList>(); foreach (var item in list) { bool result = newList.Where(o => o.lng == item.lng && o.lat == item.lat).Count()== 0; if (result) { newList.Add(item); } } FileText.WriteString(start + "|" + PointIndex); string newResult = ""; foreach (var item in newList) { //保存到数据库中,顺序标识也要保存起来PointIndex newResult += "new ResultList(){lng=" + item.lng + ",lat=" + item.lat + "},"; } FileText.WriteString("修改后的结节:" + newResult); context.Response.Write("Hello World"); } public bool IsReusable { get { return false; } } } public class ResultList { public double lng { get; set; } public double lat { get; set; } } }
显示代码如下:

Handler4代码如下(要按标识顺序读出坐标点集合):

效果图:
另：给标记点增加点击事件并弹窗（注要用到的openInfoWindow，其中enableMessage:false是把窗口上的小手机关闭）；
$.each(abc, function (item, value) { var firstPoint = new BMap.Point(value.lan, value.yan); //var startIcon = new BMap.Icon("ic_map_location.png", new BMap.Size(45, 45)); //var m1 = new BMap.Marker(firstPoint, { icon: startIcon, offset: new BMap.Size(-8, -15) }); var m1 = new BMap.Marker(firstPoint); var infoWindow = new BMap.InfoWindow("当前第"+(item+1)+"景点：厦门海底世界", { enableMessage: false, width: 30, height: 20 }); m1.addEventListener("click", function () { this.openInfoWindow(infoWindow); }); maps.addOverlay(m1); var lab1 = new BMap.Label(item + 1, { position: firstPoint, offset: new BMap.Size(-10, -25) }); lab1.setStyle({ color: "#fff", fontSize: "16px", backgroundColor: "0.05", border: "0", fontWeight: "bold" }); maps.addOverlay(lab1); });

针对弹出提示窗在For里面要使用JS的闭包功能，否则会出现所有提示全部变成最后一个，代码如下：
for (var i = 0; i < result.length; i++) { var firstPoint = new BMap.Point(result[i].PointLng, result[i].PointLat); var m1 = new BMap.Marker(firstPoint); var winfowText = "[途经点]:" + result[i].PointLable; var labText = result[i].PointOrder; if (result[i].PointType == "0" || result[i].PointType == "1") { if (result[0].PointLng == result[result.length - 1].PointLng && result[0].PointLat == result[result.length - 1].PointLat) { labText = "并"; winfowText = "[起点|终点]:" + result[0].PointLable; } else { if (result[i].PointType == "0") { labText = "起"; winfowText = "[起点]:" + result[i].PointLable; } else { labText = "终"; winfowText = "[终点]:" + result[i].PointLable; } } } (function (x) { var infoWindow = new BMap.InfoWindow(winfowText, { enableMessage: false, width: 30, height: 20 }); m1.addEventListener("click", function () { this.openInfoWindow(infoWindow); }); })(i); maps.addOverlay(m1); var lab1 = new BMap.Label(labText, { position: firstPoint, offset: new BMap.Size(-10, -25) }); lab1.setStyle({ color: "#fff", fontSize: "16px", backgroundColor: "0.05", border: "0", fontWeight: "bold" }); maps.addOverlay(lab1); }
