百度地图API开发:多边形覆盖物鼠标高亮效果及单击事件

异步加载地图

    //异步加载地图
    function loadJScript() {
        var script = document.createElement('script');
        script.type = 'text/javascript';
        script.src = '//api.map.baidu.com/api?v=2.0&ak=&ak=11Z8uiP8kIz6AG0Vjiwzbc5f9I**&callback=init';
        document.body.appendChild(script);
    }

    window.onload = loadJScript;

初始化地图

    //全局变量;
    var map;

    function init() {
        map = new BMap.Map("container", {
            enableMapClick: false,
            maxZoom: 12
        });
        var point = new BMap.Point(120.3663, 31.534519);
        map.centerAndZoom(point, 12);
        map.enableScrollWheelZoom();
        map.disableDragging();     //禁止拖拽
        // map.setMapType(BMAP_SATELLITE_MAP);

        //渲染多边形;
        getBoundary();
    }

封装函数

    //获取绘制的多边形边界;
    function getBoundary() {
        var areas = [];
        
          //建立多边形覆盖物;
        var colors = ["#fff492", "#fff492", "#98d057", "#e19ee6", "#1ad3da", "#ffc11d", "#98e800", "#b95817", "#03a9f4", "#39d0a4", "#8bbb53"];
        var ply = [];
        for (var i = 0; i
