## 实现 ##

1、插件地址

[https://github.com/turbo87/leaflet-sidebar/][https_github.com_turbo87_leaflet-sidebar]

2、下载源码，然后引入需要的L.Control.Sidebar.js文件

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6Zy46YGT5rWB5rCT5rCU6LSo_size_20_color_FFFFFF_t_70_g_se_x_16][]

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%;
                width: 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-width: 767px) {
                .leaflet-sidebar {
                    width: 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-width: 768px) and (max-width: 991px) {
                .leaflet-sidebar {
                    width: 305px;
                }
    
                .leaflet-sidebar.left.visible~.leaflet-left {
                    left: 305px;
                }
    
                .leaflet-sidebar.right.visible~.leaflet-right {
                    right: 305px;
                }
            }
    
            @media (min-width: 992px) and (max-width: 1199px) {
                .leaflet-sidebar {
                    width: 390px;
                }
    
                .leaflet-sidebar.left.visible~.leaflet-left {
                    left: 390px;
                }
    
                .leaflet-sidebar.right.visible~.leaflet-right {
                    right: 390px;
                }
            }
    
            @media (min-width: 1200px) {
                .leaflet-sidebar {
                    width: 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;
                width: 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

<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>
