我一直在使用從this V3 example的代碼來設置。當選擇不同類別的過濾器動態填充一個鏈接欄,但目前所面對的兩個問題。首先,我已經把最初的makeSidebar
功能在地圖上的閒置事件,但在地圖上移動,而不是在頁面加載時才創建工具條。其次,我似乎無法得到標記信息窗口點擊側邊欄的相應鏈接時打開。我的代碼如下:動態填充谷歌地圖側邊欄
var map;
var infowindow;
var image = [];
var gmarkers = [];
var place;
var side_bar_html = "";
image['attraction'] = 'http://google-maps-icons.googlecode.com/files/beach.png';
image['food'] = 'http://google-maps-icons.googlecode.com/files/restaurant.png';
image['hotel'] = 'http://google-maps-icons.googlecode.com/files/hotel.png';
image['city'] = 'http://google-maps-icons.googlecode.com/files/smallcity.png';
function mapInit(){
var placeLat = jQuery("#placelat").val();
var placeLng = jQuery("#placelng").val();
var centerCoord = new google.maps.LatLng(placeLat, placeLng);
var mapOptions = {
zoom: 15,
center: centerCoord,

};
map = new google.maps.Map(document.getElementById("map"), mapOptions);
google.maps.event.addListener(map, 'idle', function() {
var bounds = map.getBounds();
var ne = bounds.getNorthEast();
var sw = bounds.getSouthWest();
var yMaxLat = ne.lat();
var xMaxLng = ne.lng();
var yMinLat = sw.lat();
var xMinLng = sw.lng();
//alert("bounds changed");
updateMap(yMaxLat, xMaxLng, yMinLat, xMinLng);

任何幫助,將不勝感激 - 我能做些什麼來讓側邊欄加載頁面加載時,並獲得鏈接點擊事件的工作?謝謝!
讓我知道我是否可以做其他任何事情來幫助。 – 2010-09-13 21:50:41
歡呼聲,這是越來越接近我想要的行爲!順便說一句:謝謝你們關於陣列的問題:) – Budgie 2010-09-13 22:38:02
