即時通訊使用Asp.net和谷歌地圖API。在網站地圖上是可見的和一些字段。當用戶輸入指定的地址和半徑時,我可以得到在該位置購物的列表(使用web服務)。我在服務器端做。現在我想在Google地圖上顯示結果。asp.net +谷歌地圖API,添加標記到網站
什麼是最好的方法來做到這一點?任何scropt裝載機或類似的東西?

你可以輸出標記成一個陣列的HTML列表,然後像這樣的東西添加到地圖(未經測試,但不遠處):
var gMarkers = [['place1', 55.8, -4.020508],['place2', 53.3, -7.61],['place3', 57.9, -8.12]];
for (var i = 0; i < gMarkers.length; i++) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(lat, lon),
map: map
});
}
你可以也使用jQuery向web服務發出請求。 如果你的web服務正在返回XML,那麼有jQuery插件可以幫助你解析客戶端的數據,但Json是更好的選擇。
您是否使用ajax將注入html添加到頁面中,或者在用戶輸入地址後是否使用回發來重新加載頁面?
