html网页生成动态地图的代码实现

<script type="text/javascript">    //创建和初始化地图函数：

    function initMap() {

        createMap(); //创建地图

        setMapEvent(); //设置地图事件

        addMapControl(); //向地图添加控件

        addMarker(); //向地图中添加marker

    }

    //创建地图函数：

    function createMap() {

        var map = new BMap.Map("dituContent"); //在百度地图容器中创建一个地图

        var point = new BMap.Point(106.54904, 29.60076); //定义一个中心点坐标

        map.centerAndZoom(point, 18); //设定地图的中心点和坐标并将地图显示在地图容器中

        window.map = map; //将map变量存储在全局

    }

    //地图事件设置函数：

    function setMapEvent() {

        map.enableDragging(); //启用地图拖拽事件，默认启用(可不写)

        map.enableScrollWheelZoom(); //启用地图滚轮放大缩小

        map.enableDoubleClickZoom(); //启用鼠标双击放大，默认启用(可不写)

        map.enableKeyboard(); //启用键盘上下左右键移动地图

    }

    //地图控件添加函数：

    function addMapControl() {

        //向地图中添加缩放控件

        var ctrl_nav = new BMap.NavigationControl({ anchor: BMAP_ANCHOR_TOP_LEFT, type: BMAP_NAVIGATION_CONTROL_LARGE });
