小編給大家分享一下高德地圖WEB版怎么用,希望大家閱讀完這篇文章之后都有所收獲,下面讓我們一起去探討吧!
之前想自己做一個(gè)旅游導(dǎo)航的項(xiàng)目,在網(wǎng)上一搜發(fā)現(xiàn)了高德地圖開放平臺(tái),發(fā)現(xiàn)原來高德可以很簡(jiǎn)單的就應(yīng)用到自己的項(xiàng)目里面,當(dāng)即我就申請(qǐng)了一個(gè)key來學(xué)一學(xué),仔細(xì)研究了一下,感覺還挺難的,網(wǎng)上找了找案例什么的,經(jīng)過這幾天,小編把高德的一些基礎(chǔ)控件差不多弄了一下,效果圖如下圖所示:
下面是js代碼:
