本文實例講述了sogou地圖API應用，是非常實用的技巧。分享給大家供大家參考。具體實現方法如下：
地圖的初始化
1、添加引用地圖的API文件：
<script src="http://xiazai.VeVB.COm/201409/other/api_v2.5.1.js" type="text/javascript"></script>
2、網站初始化加載事件：
window.onload = function () { var map = new sogou.maps.Map(document.getElementById("map_canvas"), {});} 創建一個id為map_canvas的div,自定義div樣式，網站運行時地圖自動加載；
具體代碼如下
<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 {width:1000px;height: 500px;position: absolute;}@media print {#map_canvas {height: 950px;}}</style><script src="http://xiazai.VeVB.COm/201409/other/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>指定顯示莫城市地圖
關鍵代碼如下：
window.onload = function () { var myOptions = { zoom: 10,center: new sogou.maps.Point(12956000, 4824875) };//城市坐標，本坐標為北京坐標var map = new sogou.maps.Map(document.getElementById("map_canvas"), myOptions); }地圖屬性了解
列舉一下常用的一些屬性比如:地圖的移動、地圖類型轉換、跳轉到指定城市
具體代碼如下
<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.VeVB.COm/201409/other/api_v2.5.1.js" type="text/javascript"></script><script>var map;//創建全局變量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);//創建地圖 }//setMapTypeId方法示例function setMapTypeId(num) { //設置地圖類型，如： //sogou.maps.MapTypeId.ROADMAP 普通地圖 //sogou.maps.MapTypeId.SATELLITE 衛星地圖 //sogou.maps.MapTypeId.HYBRID 衛星和路網混合地圖 //map.setMapTypeId(sogou.maps.MapTypeId.HYBRID) switch (num) { case 1: map.setMapTypeId(sogou.maps.MapTypeId.ROADMAP); break; //普通地圖 case 2: map.setMapTypeId(sogou.maps.MapTypeId.SATELLITE); break; //衛星地圖 case 3: map.setMapTypeId(sogou.maps.MapTypeId.HYBRID); break; //衛星和路網混合地圖 }}//panBy方法示例地圖手動移動function panBy(a, b) { map.panBy(a, b)}//setOptions方法示例顯示指定地區function setOptions() { //同時設置地圖中心、級別、類型 map.setOptions({ center: new sogou.maps.Point(13522000, 3641093), zoom: 12, mapTypeId: sogou.maps.MapTypeId.ROADMAP })}//setCenter方法示例 顯示指定的地區 a、b為地圖坐標，C為地圖級別function setCenter(a, b, c) { map.setCenter(new sogou.maps.Point(a, b), c)}//fitBounds方法示例 跳轉到指定的范圍內function fitBounds() { //設置一個故宮附近的范圍 var bounds = new sogou.maps.Bounds(12955101, 4824738, 12958355, 4827449); //將地圖設置為可全部顯示這個范圍 //注：不是設置bounds為這個值，而是調整到合適的位置 map.fitBounds(bounds)}</script></head><body> <form id="form1" runat="server"> <input value="普通地圖" onclick="setMapTypeId(1)" type="button"/> <input value="衛星地圖" onclick="setMapTypeId(2)" type="button"/> <input value="衛星和路網混合地圖" onclick="setMapTypeId(3)" type="button"/> <input value="向左移動" onclick="panBy(200,0)" type="button"/> <input value="向右移動" onclick="panBy(-200,0)" type="button"/> <input value="向上移動" onclick="panBy(0,200)" type="button"/> <input value="向下移動" onclick="panBy(0,-200)" type="button"/> <input value="向左上移動" onclick="panBy(200,200)" type="button"/> <input value="上海" onclick="setOptions()" type="button"/> <input value="天津" onclick="setCenter(13046000,4714250,10)" type="button"/> <input value="故宮" onclick="fitBounds()" type="button"/> <div id="map_canvas" ></div> </form></body></html>地圖描點屬性
地圖上很重要的屬性，給地圖添加描點，是常用的方法屬性，
搜狗API提供兩種描點填寫形式默認描點和動態添加描點
默認描點添加：
var location = new sogou.maps.Point(12956000, 4824875); //指定描點位置var map = new sogou.maps.Map(document.getElementById("map_canvas"), {});//初始化地圖var marker = new sogou.maps.Marker({ position: location,//描點坐標 title: "描點",//描點名稱 label: { visible: true, align: "BOTTOM" },//描點顯示形式 map: map, });//添加描點到地圖動態描點添加
window.onload = function () { //初始化地圖 map = new sogou.maps.Map(document.getElementById("map_canvas"), {});//為地圖添加點擊事件sogou.maps.event.addListener(map, 'click', function (event) { var marker1 = new sogou.maps.Marker({ position: event.point, map: map }); }); }根據兩描點測距
//獲取類的唯一示例function getInstance(a) { a.hasOwnProperty("_instance") || (a._instance = new a); return a._instance}//兩點相連function Lines(myLatlng, myPoint) { var convertor = getInstance(sogou.maps.Convertor); var distance = convertor.distance(myLatlng, myPoint); //兩點鏈接 var line = new sogou.maps.Polyline({ path: [myLatlng, myPoint], strokeColor: "#FF0000", strokeOpacity: 1.0, strokeWeight: 1, title: parseInt(distance) + "米", map: map }); }根據上述屬性做了一個小的模塊，地圖上動態測距代碼如下：
<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.VeVB.COm/201409/other/api_v2.5.1.js" type="text/javascript"></script> <script> var map;var num;var Listener; //獲取類的唯一示例 function getInstance(a) { a.hasOwnProperty("_instance") || (a._instance = new a); return a._instance } window.onload = function () { //初始化地圖 map = new sogou.maps.Map(document.getElementById("map_canvas"), {}); } function AddCj() { var mypointh; var myPoint; num = 0; //為地圖添加點擊事件、點擊后顯示當前坐標并添加點擊描點 Listener = sogou.maps.event.addListener(map, 'click', function (event) { if (num == 0) { mypointh = myPoint = event.point; //獲取點擊位置的坐標 } else { myPoint = mypointh; mypointh = event.point; //獲取點擊位置的坐標 } Lines(mypointh, myPoint); num++; }); } function DelCj() { sogou.maps.event.removeListener(Listener) } //兩點相連 function Lines(myLatlng, myPoint) { var convertor = getInstance(sogou.maps.Convertor); var distance = convertor.distance(myLatlng, myPoint); //兩點鏈接 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)); } //動態添加描點，根據指定的坐標創建描點 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="測距" onclick="AddCj()" /> <input type="button" value="取消測距" onclick="DelCj()" /> <input type="button" value="清空" onclick="Mapclear()" /> <div id="map_canvas" ></div> </form></body></html>希望本文所述對大家的sogou地圖開發有所幫助
