Google Map Api和GOOGLE Search Api整合实现代码

Google Map Api和GOOGLE Search Api整合实现代码

  将GOOGLE MAP API 和 GOOGLE Search API 进行整合,我用面向对象的方式写了一个类,通过传一个经纬度进去,自动通过GOOGLE LOCAL SEARCH获取附近的相关信息。比如餐厅、景点等,反过来标到地图上,并可在任意容器内显示。

  下面是源码:

  

复制代码 代码如下:

  /*

  *Author:karry

  *Version:1.0

  *Time:2008-12-01

  *KMapSearch 类

  *把GOOGLE MAP 和LocalSearch结合。只需要传入MAP\经纬度值,就可以把该经纬度附近的相关本地搜索内容取出来,在地图上标注出来,并可以在指定容器显示搜索结果

  */

  (function() {

  var markers= new Array();

  var KMapSearch=window.KMapSearch= function(map_, opts_) {

  this.opts = {

  container:opts_.container || "divSearchResult",

  keyWord:opts_.keyWord || "餐厅",

  latlng: opts_.latlng || new GLatLng(31, 121),

  autoClear:opts_.autoClear || true,

  icon:opts_.icon || new GIcon(G_DEFAULT_ICON)

  };

  this.map = map_;

  this.gLocalSearch = new google.search.LocalSearch();

  this.gLocalSearch.setCenterPoint(this.opts.latlng);

  this.gLocalSearch.setResultSetSize(GSearch.LARGE_RESULTSET);

  this.gLocalSearch.setSearchCompleteCallback(this, function() {

  if (this.gLocalSearch.results) {

  var savedResults = document.getElementById(this.opts.container);

  if (this.opts.autoClear) {

  savedResults.innerHTML = "";

  }

  for (var i = 0; i < this.gLocalSearch.results.length; i++) {

  savedResults.appendChild(this.getResult(this.gLocalSearch.results[i]));

  }

  }

  });

  }

  KMapSearch.prototype.getResult = function(result) {

  var container = document.createElement("div");

  container.className = "list";

  var myRadom =(new Date()).getTime().toString()+Math.floor(Math.random()*10000);

  container.id=myRadom;

  container.innerHTML = result.title + "<br />地址:" + result.streetAddress;

  this.createMarker(new GLatLng(result.lat, result.lng), result.html,myRadom);

  return container;

  }

  KMapSearch.prototype.createMarker = function(latLng, content)

  {

  var marker = new GMarker(latLng, {icon:this.opts.icon,title:this.opts.title});

  GEvent.addListener(marker, "click", function() {

  marker.openInfoWindowHtml(content);

  });

  markers.push(marker);

  map.addOverlay(marker);

  }

  KMapSearch.prototype.clearAll = function() {

  for (var i = 0; i < markers.length; i++) {

  this.map.removeOverlay(markers[i]);

  }

  markers.length = 0;

  }

  KMapSearch.prototype.execute = function(latLng) {

  if (latLng) {

  this.gLocalSearch.setCenterPoint(latLng);

  }

  this.gLocalSearch.execute(this.opts.keyWord);

  }

  })();

  使用方法:

  

复制代码 代码如下:

  var myIcon = new GIcon(G_DEFAULT_ICON);

  myIcon.image = "canting.png";

  myIcon.iconSize = new GSize(16, 20);

  myIcon.iconAnchor = new GPoint(8, 20);

  myIcon.shadow = "";

  var mapSearch = new KMapSearch(map, {container:"cantingContainer",latlng:initPt,icon:myIcon,keyWord:"餐厅"});

  mapSearch.clearAll();

  mapSearch.execute();
