openlayers6地圖切換展示(附源碼下載)

 路人甲Java 2021-11-20

前言

之前寫(xiě)過(guò)一篇openlayers4版本的地圖切換效果，但是由于是封裝一層 js代碼寫(xiě)的，很多初學(xué)者看起來(lái)比較有點(diǎn)吃力，所以本篇文章重新寫(xiě)一篇地圖切換效果，直接基于最新版本openlayers6寫(xiě)的，純粹html + js + css形式，沒(méi)有任何封裝。

內(nèi)容概覽

1.基于openlayers6實(shí)現(xiàn)地圖切換展示效果
2.源代碼demo下載

效果圖如下：

大概實(shí)現(xiàn)思路如下：地圖初始化配置加載各種在線地圖，比如天地圖，arcgis地圖，谷歌地圖，高德地圖，百度地圖，OSM地圖等等，默認(rèn)圖層只顯示一個(gè)地圖，其他在線地圖默認(rèn)隱藏不可見(jiàn)狀態(tài)；js自定義一個(gè)底圖切換的控件，底圖切換時(shí)候，動(dòng)態(tài)設(shè)置圖層的隱藏以及可見(jiàn)性，達(dá)到底圖切換目的。
