实现
1、插件地址
/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%;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
<!-- 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="/BADAO_LIUMANG_QIZHI">霸道流氓气质</a></li></ul></div>
5、完整示例代码，注释见代码
