百度地圖 遇到了一個默明奇妙的bug..... 調用後中心點 不再 point(標註的點上...)這是需要執行一次(僅一次) 當 地圖 加載完後 執行(這個方法你每次改地圖 都會執行...所以讓他執行一次......因為這個問題只會在 首次出現...)

 //百度地圖的 js ....
    var userLocation = {la: 0, lg: 0};

    //定義一個 變量.標誌 方法只能執行一次...在執行完 百度 tilesloaded 後 將此變量設為 false...
    var flag = true;

    //只能執行一次的方法.....
    function initBaiduMap() {
        
 
if (userLocation.la === 0 || userLocation.lg === 0) {
            //給保定的位置
            userLocation.la = 38.87;
            userLocation.lg = 115.47;
        }
        // 百度地圖API功能
        var map = new BMap.Map("allmap");
        var point = new BMap.Point(userLocation.lg, userLocation.la);
        map.centerAndZoom(point, 
 
18);
        var local = new BMap.LocalSearch(map, {
            renderOptions: {map: map}
        });
        map.enableScrollWheelZoom(true);
        map.addControl(new BMap.MapTypeControl({
            mapTypes: [
                BMAP_NORMAL_MAP,
                BMAP_HYBRID_MAP
            ]
        }));
        
 
//添加工具欄
        var top_left_control = new BMap.ScaleControl({anchor: BMAP_ANCHOR_TOP_LEFT});// 左上角，添加比例尺
        var top_left_navigation = new BMap.NavigationControl();  //左上角，添加默認縮放平移控件
        var top_right_navigation = new BMap.NavigationControl({
            anchor: BMAP_ANCHOR_TOP_RIGHT,
            type: BMAP_NAVIGATION_CONTROL_SMALL
        });
        map.addControl(top_right_navigation);

        map.addEventListener(‘tilesloaded‘, function () {
            //加載完成是有一個bug...該bug會導致..點偏移一次....這個方法只應該執行一次----
            //默認檢索...高陽縣
