將GOOGLE MAP API 和 GOOGLE Search API 進行整合，我用面向對象的方式寫了一個類，通過傳一個經緯度進去，自動通過GOOGLE LOCAL SEARCH獲取附近的相關信息。比如餐廳、景點等，反過來標到地圖上，并可在任意容器內顯示。
下面是源碼：
復制代碼 代碼如下:
/*
*Author:karry
*Version:1.0
*Time:2008-12-01
*KMapSearch 類
*把GOOGLE MAP 和LocalSearch結合。只需要傳入MAP/經緯度值，就可以把該經緯度附近的相關本地搜索內容取出來，在地圖上標注出來，并可以在指定容器顯示搜索結果
*/

(function() {
var markers= new Array();
var KMapSearch=window.KMapSearch= function(map_, opts_) {
this.opts = {
container:opts_.container || "divSearchResult",
keyWord:opts_.keyWord || "餐廳",
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：
復制代碼 代碼如下:
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:"餐廳"});
mapSearch.clearAll();
mapSearch.execute();
