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 }); }); }
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) + "米", map: map }); }
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：
