高德地图API之地图搜索+兴趣点POI+标记点操作
使用AMap.Autocomplete() 自动补全插件，实现搜索功能
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>map</title> <script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=ce3b1a3a7e67fc75810ce1ba1f83c01a"></script> <style> *{margin:0;padding:0;} #container {width:100%; height: 100%;top:0;left:0;position: absolute; } #setZoomNode{width:400px;height:100px;background-color: #fff;border:1px solid;box-shadow:0 0 5px #000;top:20px;right:20px;position: absolute;} </style> </head> <body> <div id="container"></div> <div id="setZoomNode"> 鼠标点击的经纬度：<span id="xy"></span> </div> <script> var map=new AMap.Map("container"); //加载AMap.Autocomplete自动补全插件 AMap.plugin("AMap.Autocomplete",function(){ console.log("插件加载完成"); //使用插件的搜索功能 new AMap.Autocomplete().search("宁波",function(status,data){ console.log(data); }) }) </script> </body> </html>
使用自动补全搜索，并展示出来。点击后可以定位
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>map</title> <script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=ce3b1a3a7e67fc75810ce1ba1f83c01a"></script> <style> *{margin:0;padding:0;list-style: none;} #container {width:100%; height: 100%;top:0;left:0;position: absolute; } #setZoomNode{width:200px;height:500px;background-color: #fff;border:1px solid;box-shadow:0 0 5px #000;top:20px;right:20px;position: absolute;} #node li{cursor:pointer;} </style> </head> <body> <div id="container"></div> <div id="setZoomNode"> <input type="text" id="txt"> <ul id="node"></ul> </div> <script> var map=new AMap.Map("container"); //加载AMap.Autocomplete自动补全插件 AMap.plugin("AMap.Autocomplete",function(){ //console.log("插件加载完成"); txt.oninput=function(){ node.innerHTML=""; //console.log(this.value);//输入框中的文本 if(this.value=="") return; //使用插件的搜索功能 new AMap.Autocomplete().search(this.value,function(status,data){ for(var i=0;i<data.tips.length;i++){ var oli=document.createElement("li"); oli.innerHTML=data.tips[i].name; //将坐标赋值给属性 oli.r=data.tips[i].location.R; oli.q=data.tips[i].location.Q; node.appendChild(oli); //oli点击事件 oli.onclick=function(){ console.log(this.r+","+this.q); map.setCenter([this.r,this.q]); } } //console.log(data); }) } }) </script> </body> </html>
点击之后自动设置中心点
插件还有另一种方式来加载 &plugin=
<script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=ce3b1a3a7e67fc75810ce1ba1f83c01a&plugin=AMap.Autocomplete"></script>
调用也有另一种方式（官方提供，自带下拉样式）
new AMap.Autocomplete({
input:"txt"
})
完整代码：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>map</title> <script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=ce3b1a3a7e67fc75810ce1ba1f83c01a&plugin=AMap.Autocomplete"></script> <style> *{margin:0;padding:0;list-style: none;} #container {width:100%; height: 100%;top:0;left:0;position: absolute; } #setZoomNode{width:200px;height:500px;background-color: #fff;border:1px solid;box-shadow:0 0 5px #000;top:20px;right:20px;position: absolute;} #node li{cursor:pointer;} </style> </head> <body> <div id="container"></div> <div id="setZoomNode"> <input type="text" id="txt"> </div> <script> var map=new AMap.Map("container"); //官方给出的搜索方式 new AMap.Autocomplete({ input:"txt" }) </script> </body> </html>
输入提示与POI结合
POI =》 point of interest 兴趣点
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>map</title> <script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=ce3b1a3a7e67fc75810ce1ba1f83c01a&plugin=AMap.Autocomplete"></script> <style> *{margin:0;padding:0;list-style: none;} #container {width:100%; height: 100%;top:0;left:0;position: absolute; } #setZoomNode{width:280px;background-color: #fff;border:1px solid;box-shadow:0 0 5px #000;top:20px;right:20px;position: absolute;} #node li{cursor:pointer;} </style> </head> <body> <div id="container"></div> <div id="setZoomNode"> </div> <script> var map=new AMap.Map("container"); //兴趣点服务 AMap.service(["AMap.PlaceSearch"],function(){ new AMap.PlaceSearch({ pageSize:5,//一页显示几条 pageIndex:1,//默认是1，可不写 city:"0574",//城市区号 map:map,//地图名 panel:"setZoomNode"//数据装载容器 }).search("电影院"); }) </script> </body> </html>
需要注意的是：只有在服务器上才能显示图片
通过输入框搜索
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>map</title> <script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.15&key=ce3b1a3a7e67fc75810ce1ba1f83c01a&plugin=AMap.Autocomplete"></script> <style> *{margin:0;padding:0;list-style: none;} #container {width:100%; height: 100%;top:0;left:0;position: absolute; } #setZoomNode{width:280px;background-color: #fff;border:1px solid;box-shadow:0 0 5px #000;top:50px;right:20px;position: absolute;} #node li{cursor:pointer;} #searchNode{width:280px;height:30px;background:#fff;position: absolute;top:20px;right:20px;} </style> </head> <body> <div id="container"></div> <div id="searchNode"> <input type="text" id="searchIpt"> <button id="btn">搜索</button> </div> <div id="setZoomNode"> </div> <script> var map=new AMap.Map("container"); btn.onclick=function(){ //兴趣点服务 AMap.service(["AMap.PlaceSearch"],function(){ new AMap.PlaceSearch({ pageSize:4,//一页显示几条 pageIndex:1,//默认是1，可不写 city:"0574",//城市区号 cityLimit:true,//限制城市 map:map,//地图名 panel:"setZoomNode"//数据装载容器 }).search(searchIpt.value); }) } </script> </body> </html>
二者结合使用的demo
AMap事件监听
AMap.event.addListener(searchVal,"select",function(e){
//输入地址，选中某个具体地址时触发
console.log(e);
})
