实现

1、插件地址

https://github.com/turbo87/leaflet-sidebar/

2、下载源码，然后引入需要的L.Control.Sidebar.js文件

3、css文件不再单独引入，直接放在html中

        .leaflet-sidebar {
            position: absolute;
            height: 100%;
            -webkit-box-sizing: border-box;
            -moz-box-sizing: border-box;
            box-sizing: border-box;
            padding: 10px;
            z-index: 2000;
        }

        .leaflet-sidebar.left {
            left: -500px;
            transition: left 0.5s, width 0.5s;
            padding-right: 0;
        }

        .leaflet-sidebar.left.visible {
            left: 0;
        }

        .leaflet-sidebar.right {
            right: -500px;
            transition: right 0.5s, width 0.5s;
            padding-left: 0;
        }

        .leaflet-sidebar.right.visible {
            right: 0;
        }

        .leaflet-sidebar>.leaflet-control {
            height: 100%;
             100%;
            overflow: auto;
            -webkit-overflow-scrolling: touch;
            -webkit-box-sizing: border-box;
            -moz-box-sizing: border-box;
            box-sizing: border-box;
            padding: 8px 24px;
            font-size: 1.1em;
            background: white;
            box-shadow: 0 1px 7px rgba(0, 0, 0, 0.65);
            -webkit-border-radius: 4px;
            border-radius: 4px;
        }

        .leaflet-touch .leaflet-sidebar>.leaflet-control {
            box-shadow: none;
            border: 2px solid rgba(0, 0, 0, 0.2);
            background-clip: padding-box;
        }

        @media (max- 767px) {
            .leaflet-sidebar {
                 100%;
                padding: 0;
            }

            .leaflet-sidebar.left.visible~.leaflet-left {
                left: 100%;
            }

            .leaflet-sidebar.right.visible~.leaflet-right {
                right: 100%;
            }

            .leaflet-sidebar.left {
                left: -100%;
            }

            .leaflet-sidebar.left.visible {
                left: 0;
            }

            .leaflet-sidebar.right {
                right: -100%;
            }

            .leaflet-sidebar.right.visible {
                right: 0;
            }

            .leaflet-sidebar>.leaflet-control {
                box-shadow: none;
                -webkit-border-radius: 0;
                border-radius: 0;
            }

            .leaflet-touch .leaflet-sidebar>.leaflet-control {
                border: 0;
            }
        }

        @media (min- 768px) and (max- 991px) {
            .leaflet-sidebar {
                 305px;
            }

            .leaflet-sidebar.left.visible~.leaflet-left {
                left: 305px;
            }

            .leaflet-sidebar.right.visible~.leaflet-right {
                right: 305px;
            }
        }

        @media (min- 992px) and (max- 1199px) {
            .leaflet-sidebar {
                 390px;
            }

            .leaflet-sidebar.left.visible~.leaflet-left {
                left: 390px;
            }

            .leaflet-sidebar.right.visible~.leaflet-right {
                right: 390px;
            }
        }

        @media (min- 1200px) {
            .leaflet-sidebar {
                 460px;
            }

            .leaflet-sidebar.left.visible~.leaflet-left {
                left: 460px;
            }

            .leaflet-sidebar.right.visible~.leaflet-right {
                right: 460px;
            }
        }

        .leaflet-sidebar .close {
            position: absolute;
            right: 20px;
            top: 20px;
             31px;
            height: 31px;
            color: #333;
            font-size: 25pt;
            line-height: 1em;
            text-align: center;
            background: white;
            -webkit-border-radius: 16px;
            border-radius: 16px;
            cursor: pointer;
            z-index: 8;
        }

        .leaflet-left {
            transition: left 0.5s;
        }

        .leaflet-right {
            transition: right 0.5s;
        }

4、除了显示地图的div之外，再添加侧边栏显示的内容

    <!-- 侧边栏弹窗显示的内容 -->
    <div id="sidebar">
        <h1>公众号</h1>

        <p>霸道的程序猿</p>

        <p><b>我的CSDN</b></p>

        <p></p>

        <ul>
            <li><a href="https://blog.csdn.net/BADAO_LIUMANG_QIZHI">霸道流氓气质</a></li>
        </ul>

    </div>
