摘要:地图服务,大家能想到哪些?POI搜素,输入提示,地址解析,公交导航,驾车导航,步行导航,道路查询(交叉口),行政区划等等。如果说覆盖物Marker是地图的骨骼,那么服务,就是地图的气血。有个各种各样的地图服务,我们的地图应用才能变得有血有肉,活灵活现。第四篇拆成了几个要点,本篇主要讲搜索服务。包括周边搜索,关键词搜索,范围搜索,搜索提示(自动完成,输入提示),行政区域,交叉路口,检索自有数据(云图)。

---------------------------------------------------------------------------------------

一、POI搜索

1、关键字查询

使用search方法,传一个关键词参数即可。

 MSearch.search(‘东方明珠‘); //关键字查询 

 

完整代码:

//关键词查询function placeSearch1() {      var MSearch;      mapObj.plugin(["AMap.PlaceSearch"], function() {                  MSearch = new AMap.PlaceSearch({ //构造地点查询类              pageSize:10,              pageIndex:1,              city:"021" //城市          });           AMap.event.addListener(MSearch, "complete", keywordSearch_CallBack);//返回地点查询结果          MSearch.search(‘东方明珠‘); //关键字查询      });  }

2、输入提示

html部分:

    <div class="autoclass">        <input type="text" id="keyword" name="keyword" value="" style="width: 95%;"/>          <div id="result1" class="autobox" name="result1"></div>    </div>

 

JS部分:

在地图初始化时,添加【自动完成/输入提示】插件。

    //加载输入提示插件      mapObj.plugin(["AMap.Autocomplete"], function() {          //判断是否IE浏览器          if (navigator.userAgent.indexOf("MSIE") > 0) {              document.getElementById("keyword").onpropertychange = autoSearch;          }          else {              document.getElementById("keyword").oninput = autoSearch;          }      }); 

 

输入提示部分:

//输入提示  function autoSearch() {       var keywords = document.getElementById("keyword").value;      var auto;        var autoOptions = {          pageIndex:1,          pageSize:10,          city: "" //城市,默认全国      };      auto = new AMap.Autocomplete(autoOptions);      //查询成功时返回查询结果      AMap.event.addListener(auto, "complete", autocomplete_CallBack);      auto.search(keywords);  }

3、周边查询

使用searchNearBy方法,需要传入关键词,中心点经纬度,搜索半径。

MSearch.searchNearBy("酒店", cpoint, 500);  

 

全部代码:

//周边查询函数  var cpoint = new AMap.LngLat(116.405467,39.907761); //搜索查询的中心点设置function placeSearch2() {      var MSearch;      //加载服务插件,实例化地点查询类        mapObj.plugin(["AMap.PlaceSearch"], function() {          MSearch = new AMap.PlaceSearch({               city: "北京"          });           //查询成功时的回调函数          AMap.event.addListener(MSearch, "complete", keywordSearch_CallBack);           //周边搜索          MSearch.searchNearBy("酒店", cpoint, 500);       });  }

4、可视区域查询 5、范围内查询

范围内查询,可以是多边形,可以是圆形,也可以是矩形。

我们在这里,用一个矩形搜索来举例。

使用searchInBounds方法,传入关键词,与范围即可。

MSearch.searchInBounds("酒店", new AMap.Bounds(arr[0], arr[2])); //范围查询

 

可视区域,就是视野内查询,这时可以获取整个可视区域,把这个区域传给范围内搜索即可。

mapObj.getBounds(); //获取可视区域范围

 

全部代码:

//范围内搜索-矩形function placeSearch3(){      clearMap();      var arr = new Array();      var MSearch;      //绘制矩形边框         arr.push(new AMap.LngLat("116.423321","39.884055"));       arr.push(new AMap.LngLat("116.473103","39.884055"));       arr.push(new AMap.LngLat("116.473103","39.919348"));       arr.push(new AMap.LngLat("116.423321","39.919348"));      var polygon = new AMap.Polygon({          map:mapObj,           path:arr,           strokeColor:"#0000ff",           strokeOpacity:0.2,           strokeWeight:3,           fillColor: "#f5deb3",           fillOpacity: 0.8       });         mapObj.plugin(["AMap.PlaceSearch"], function() { //加载PlaceSearch服务插件                MSearch = new AMap.PlaceSearch({              pageSize: 8          }); //构造地点查询类          AMap.event.addListener(MSearch, "complete", Search_CallBack); //查询成功时的回调函数          MSearch.searchInBounds("酒店", new AMap.Bounds(arr[0], arr[2])); //范围查询      });  }

6、道路查询(交叉口)

如果要查询北京的101国道,需要传参数‘101’和‘北京’。

//道路交叉口function roadCrossSearchByRoadName(){        var roadname = ‘101‘;        var city2 = ‘北京‘;        var RoadSearchOption = {            number:10,//每页数量,默认10            batch:1,//请求页数,默认1            ext:""//扩展字段            };        var road = new AMap.RoadSearch(RoadSearchOption);      road.roadCrossSearchByRoadName(roadname,city2,roadCrossSearch_CallBack);  }

7、自有数据检索(不需要数据库)

检索自有数据,是我的最爱。其实就是使用云图就好了。

显示云图层,需要获得自己的tableID:

//叠加云数据图层  function addCloudLayer() {      clearMap();    //加载云图层插件      mapObj.plugin(‘AMap.CloudDataLayer‘, function () {          var layerOptions = {               query:{keywords: ‘‘},               clickable:true          };          cloudDataLayer = new AMap.CloudDataLayer(‘533ccc56e4b08ebff7d539eb‘, layerOptions); //实例化云图层类          cloudDataLayer.setMap(mapObj); //叠加云图层到地图 }

通过云图的云检索功能,检索出自有数据中的“酒店”。并用图片为A-H的标注进行标示。

云检索:

function cloudSearch(){    var arr = new Array();          var search;      var searchOptions = {          keywords:‘酒店‘,          orderBy:‘_id:ASC‘      };      //加载CloudDataSearch服务插件      mapObj.plugin(["AMap.CloudDataSearch"], function() {                 search = new AMap.CloudDataSearch(‘5358f853e4b01214f369d851‘, searchOptions); //构造云数据检索类          AMap.event.addListener(search, "complete", cloudSearch_CallBack); //查询成功时的回调函数          AMap.event.addListener(search, "error", errorInfo); //查询失败时的回调函数          search.searchNearBy(yunPoint, 10000); //周边检索      }); }

 

检索成功的回调函数:

function cloudSearch_CallBack(data) {       var resultStr="";      var resultArr = data.datas;      var resultNum = resultArr.length;        for (var i = 0; i < resultNum; i++) {            resultStr += "<div id=‘divid" + (i+1) + "‘ onm ouseover=‘openMarkerTipById1(" + i + ",this)‘ onm ouseout=‘onmouseout_MarkerStyle(" + (i+1) + ",this)‘ style=\"font-size: 12px;cursor:pointer;padding:2px 0 4px 2px; border-bottom:1px solid #C1FFC1;\"><table><tr><td><h3><font face=\"微软雅黑\"color=\"#3366FF\">" + (i+1) + "." + resultArr[i]._name + "</font></h3>";          resultStr += ‘地址:‘ + resultArr[i]._address + ‘<br/>类型:‘ + resultArr[i].type + ‘<br/>ID:‘ + resultArr[i]._id + "</td></tr></table></div>";          addmarker(i, resultArr[i]);      }      mapObj.setFitView();      document.getElementById("result").innerHTML = resultStr;  }  

 

添加Marker:

//添加marker&infowindow      function addmarker(i, d) {      var lngX;     var latY;    var iName;    var iAddress;    if(d.location){        lngX = d.location.getLng();          latY = d.location.getLat();      }else{        lngX = d._location.getLng();          latY = d._location.getLat();     }    if(d.name){        iName = d.name;    }else{        iName = d._name;    }    if(d.name){        iAddress = d.address;    }else{        iAddress = d._address;    }    var markerOption = {          map:mapObj,          icon:"http://webapi.amap.com/images/" + (i + 1) + ".png",          position:new AMap.LngLat(lngX, latY)      };      var mar = new AMap.Marker(markerOption);                marker.push(new AMap.LngLat(lngX, latY));        var infoWindow = new AMap.InfoWindow({          content:"<h3><font color=\"#00a6ac\">" + (i + 1) + ". " + iName + "</font></h3>" + TipContents(d.type, iAddress, d.tel),          size:new AMap.Size(300, 0),           autoMove:true,            offset:new AMap.Pixel(0,-30)      });      windowsArr.push(infoWindow);       var aa = function (e) {infoWindow.open(mapObj, mar.getPosition());};      AMap.event.addListener(mar, "click", aa);  }
