高德地图点击查询信息定位到点+异步加载点+点击点显示信息窗口

一：配置地图  

     根据官方步骤申请key

    可以异步或者同步调用地图，此处Wie同步

   html

•  <div id="container" tabindex="0"></div>

 js

 //设置中心位置,显示当前城市的中心点
    var map = new AMap.Map('container', {
        resizeEnable: true,
        //center: [117.031479, 36.66314],//定位的济南//center缺省则根据IP自动获取中心
        zoom: 11
    });

　　不设置center可以根据ip自动获取中心位置

二：配置地图标记点

   

    
    var style = new AMap.Icon({
        size: new AMap.Size(30, 40),  //图标大小
        image: "img/map_icon.png",//设置点图标图像
        imageSize: new AMap.Size(25, 28),
        imageOffset: new AMap.Pixel(0, 0)
    });
    //显示窗口
   var infoWindow = new AMap.InfoWindow({
        draggable: true,  //是否可拖动
        content: "",
        isCustom: true,
        //使用自定义窗体
        offset: new AMap.Pixel(16, -15) //基点指向marker的头部位置
    });
    

        var markerList = [];//存放地图的点信息，方便点击时加载

        //清除地图上的信息
        map.remove(markers);
        map.clearInfoWindow();

        $.post('ashx/dealHandler.ashx',
            {
                action: "getPoints",
                page: page,//当前页码
                pageSize: pageSize,//每页页码（此处取全局参数）
                city: $("#city").val(),
                searchText: $(".ipt_search").val()
            },
            function (result) {
                if (result.total > 0) {//用模板加载信息
                    var ht = template("tmp-list1",
                        {
                            Data: result.rows
                        });
                    $("#project_item").empty().append(ht);//模板赋值
                    $("#countAll").text(result.total);
                    //获取分页数据
                    GetLayuiPageList(result.total, page, pageSize);
                  
                   //左侧查询信息的点击事件，要在绘制完成后加载
                    $('.dz_text').on('click', function () {

                        var idStr = this.dataset.id;
                        markerList.map(function(value,index){
                             
                            if (value.id == idStr) {
                               //获取点击点的marker
                                var tpmk = value.marker_o;
                                if (tpmk) {
                                    //触发点击
                                    tpmk.emit('click', { target: tpmk });
                                    //设置中心点和缩放比例
                                    map.setZoomAndCenter(15, 
                                    tpmk.getPosition());
                                }
                            }
                        })
                    })
                    //在地图标记点
                    var marker;
                    var firstlng,firstlat;
