sogou地图API用法实例教程(2)
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 =
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
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
});
});
}
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：
<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 {width:1000px;height: 500px;position: absolute;}
@media print {#map_canvas {height: 950px;}}
</style>
<script src="http://xiazai.jb51.net/201409/other/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) + "米",
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+"米",
label:{visible:true,align:"BOTTOM"},
map: map
});
}
function Mapclear() {
num = 0;
map.clearAll();
}
</script>
</head>
<body>
<form id="form1" runat="server">
<input type="button" value="测距" onclick="AddCj()" />
<input type="button" value="取消测距" onclick="DelCj()" />
<input type="button" value="清空" onclick="Mapclear()" />
<div id="map_canvas" ></div>
</form>
</body>
</html>
