最近做項(xiàng)目，有個(gè)需求使用到高德地圖JS API，現(xiàn)寫(xiě)博客總結(jié)一下。

需求要求大概是這樣的：

• 使用地圖高德或百度或谷歌都可以（這里吐槽一下，百度地圖的jsAPI幫助文檔寫(xiě)的太。。。谷歌你懂的。。。高德目前感覺(jué)非常nice）
• 需要根據(jù)用戶定位獲取周邊片區(qū)相關(guān)數(shù)據(jù)統(tǒng)計(jì)，并展示
• 頭部根據(jù)用戶點(diǎn)擊poi點(diǎn)信息而變更
• 點(diǎn)擊左上列表任意一列，地圖中心自動(dòng)切換并展示出信息框
• 效果圖如下：

緊接著帶著需求我就去高德地圖JSAPI尋找解決辦法，很驚喜發(fā)現(xiàn)有相關(guān)解決辦法，高德地圖JSAPI-UI組件事例中，標(biāo)注列表-完整事例?比較接近，只要稍微改造一下即可。

具體代碼如下：
