1.引入百度地图脚本

2.定义HTML容器

3.js脚本代码

<script>
        var map = new BMap.Map("container");

        var point = new BMap.Point(114.025973657, 22.5460535462);
        map.centerAndZoom(point, 15);

        map.enableScrollWheelZoom(true);

        // 弹窗
        var opts = {
            width: 270, // 信息窗口宽度
            height: 100, // 信息窗口高度
            enableMessage: true //设置允许信息窗发送短息
        };

        // 弹窗点击事件
        function openInfo(content, e) {
