  • C# sogou地图API应用总结

    地图的初始化
    1、添加引用地图的API文件: <script src="http://api.go2map.com/maps/js/api_v2.5.1.js" type="text/javascript"></script>
    2、网站初始化加载事件: window.onload = function () { var map = new sogou.maps.Map(document.getElementById("map_canvas"), {}); }
    创建一个id为map_canvas的div,自定义div样式,网站运行时地图自动加载;

    具体代码如下

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title></title>
        <style type="text/css">
    html {height: auto;}
    body {height: auto;margin: 0;padding: 0;}
    #map_canvas {1000px;height: 500px;position: absolute;}
    @media print {#map_canvas {height: 950px;}}
    </style>
    
        <script src="http://api.go2map.com/maps/js/api_v2.5.1.js" type="text/javascript"></script>
        <script>
            window.onload = function () {
                var map = new sogou.maps.Map(document.getElementById("map_canvas"), {});
    
            } 
        </script>
    </head>
    <body>
        <form id="form1" runat="server">
        <div id="map_canvas"></div>
        </form>
    </body>
    </html>
    View Code

    指定显示莫城市地图

    关键代码:

     window.onload = function () { 
     var myOptions = { zoom: 10,center: new sogou.maps.Point(12956000, 4824875) };//城市坐标,本坐标为北京坐标
     var map = new sogou.maps.Map(document.getElementById("map_canvas"), myOptions); 
     } 
    View Code

    地图属性了解

    列举一下常用的一些属性比如:地图的移动、地图类型转换、跳转到指定城市

    具体代码如下

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head id="Head1" runat="server">
        <title></title>
        <style type="text/css">
    html {height: auto;}
    body {height: auto;margin: 0;padding: 0;}
    #map_canvas {1000px;height: 500px;position: absolute;}
    @media print {#map_canvas {height: 950px;}}
    </style>
    
        <script src="http://api.go2map.com/maps/js/api_v2.5.1.js" type="text/javascript"></script>
        <script>
            var map;//创建全局变量
           
            window.onload = function () { 
                var myOptions = { zoom: 10, center: new sogou.maps.Point(12956000, 4824875) };//指定城市
                map = new sogou.maps.Map(document.getElementById("map_canvas"), myOptions);//创建地图 
    
            }
    
         
             //setMapTypeId方法示例
            function setMapTypeId(num) { 
                //设置地图类型,如:
                //sogou.maps.MapTypeId.ROADMAP 普通地图
                //sogou.maps.MapTypeId.SATELLITE 卫星地图
                //sogou.maps.MapTypeId.HYBRID 卫星和路网混合地图
                //map.setMapTypeId(sogou.maps.MapTypeId.HYBRID)
                switch (num) {
                    case 1: map.setMapTypeId(sogou.maps.MapTypeId.ROADMAP); break; //普通地图
                    case 2: map.setMapTypeId(sogou.maps.MapTypeId.SATELLITE); break; //卫星地图
                    case 3: map.setMapTypeId(sogou.maps.MapTypeId.HYBRID); break; //卫星和路网混合地图
                }
            }
            //panBy方法示例地图手动移动
            function panBy(a, b) {
                map.panBy(a, b)
            }
            //setOptions方法示例显示指定地区
            function setOptions() {
                //同时设置地图中心、级别、类型
                map.setOptions({ center: new sogou.maps.Point(13522000, 3641093), zoom: 12, mapTypeId: sogou.maps.MapTypeId.ROADMAP })
            }
            //setCenter方法示例 显示指定的地区 a、b为地图坐标,C为地图级别
            function setCenter(a, b, c) {
                map.setCenter(new sogou.maps.Point(a, b), c)
            }
            //fitBounds方法示例 跳转到指定的范围内
            function fitBounds() {
                //设置一个故宫附近的范围
                var bounds = new sogou.maps.Bounds(12955101, 4824738, 12958355, 4827449);
                //将地图设置为可全部显示这个范围
                //注:不是设置bounds为这个值,而是调整到合适的位置
                map.fitBounds(bounds)
            }
    
    
    
        </script>

     地图描点属性

    地图上很重要的属性,给地图添加描点,是常用的方法属性,

    搜狗API提供两种描点填写形式默认描点和动态添加描点

    默认描点添加:

      var location = new sogou.maps.Point(12956000, 4824875); //指定描点位置
    var map = new sogou.maps.Map(document.getElementById("map_canvas"), {});//初始化地图
     var marker = new sogou.maps.Marker({
                    position: location,//描点坐标
                    title: "描点",//描点名称
                    label: { visible: true, align: "BOTTOM" },//描点显示形式
                    map: map, 
                });//添加描点到地图
    View Code

    动态描点添加

      window.onload = function () { 
            //初始化地图
                map = new sogou.maps.Map(document.getElementById("map_canvas"), {});
    //为地图添加点击事件
     sogou.maps.event.addListener(map, 'click', function (event) {
                    var marker1 = new sogou.maps.Marker({
                    position: event.point, 
                    map: map
                });
                }); 
            }
    View Code

    根据两描点测距

    //获取类的唯一示例
            function getInstance(a) {
                a.hasOwnProperty("_instance") || (a._instance = new a);
                return a._instance
            }
     //两点相连
            function Lines(myLatlng, myPoint) { 
                var convertor = getInstance(sogou.maps.Convertor);
                var distance = convertor.distance(myLatlng, myPoint);
                //两点链接
                var line = new sogou.maps.Polyline({
                    path: [myLatlng, myPoint],
                    strokeColor: "#FF0000",
                    strokeOpacity: 1.0,
                    strokeWeight: 1,
                    title: parseInt(distance) + "",
                    map: map
                }); 
            }
    View Code

    根据上述属性做了一个小的模块,地图上动态测距代码如下:

    <html xmlns="http://www.w3.org/1999/xhtml">
    <head id="Head1" runat="server">
        <title></title>
        <style type="text/css">

    body {height: auto;margin: 0;padding: 0;}
    #map_canvas {1000px;height: 500px;position: absolute;}
    @media print {#map_canvas {height: 950px;}}
    </style>
    
        <script src="http://api.go2map.com/maps/js/api_v2.5.1.js" type="text/javascript"></script>
        <script>
            var map;var num;var Listener;
            //获取类的唯一示例
            function getInstance(a) {
                a.hasOwnProperty("_instance") || (a._instance = new a);
                return a._instance
            }
    
            window.onload = function () { 
            //初始化地图
                map = new sogou.maps.Map(document.getElementById("map_canvas"), {}); 
            }
            function AddCj() {
                var mypointh; var myPoint;
                num = 0;
                //为地图添加点击事件、点击后显示当前坐标并添加点击描点
                Listener = sogou.maps.event.addListener(map, 'click', function (event) {
                    if (num == 0) {
                        mypointh = myPoint = event.point; //获取点击位置的坐标  
                    }
                    else {
                        myPoint = mypointh;
                        mypointh = event.point; //获取点击位置的坐标  
                    }
                    Lines(mypointh, myPoint);
                    num++;
                });
            }
            function DelCj() {
                sogou.maps.event.removeListener(Listener)
            }
    
            //两点相连
            function Lines(myLatlng, myPoint) { 
                var convertor = getInstance(sogou.maps.Convertor);
                var distance = convertor.distance(myLatlng, myPoint);
                //两点链接
                var line = new sogou.maps.Polyline({
                    path: [myLatlng, myPoint],
                    strokeColor: "#FF0000",
                    strokeOpacity: 1.0,
                    strokeWeight: 1,
                    title: parseInt(distance) + "",
                    map: map
                });
                placeMarker(myLatlng, parseInt(distance));
            }
    
    
            //动态添加描点,根据指定的坐标创建描点
            function placeMarker(location,jl) {
                var clickedLocation = location;
                var marker1 = new sogou.maps.Marker({
                    position: location,
                    title: jl+"",
                    label:{visible:true,align:"BOTTOM"},
                    map: map
                });
            }
    
            function Mapclear() {
                num = 0;
                map.clearAll();
            }
    
        </script>
