這篇文章主要為大家詳細(xì)介紹了簡(jiǎn)單實(shí)現(xiàn)js選項(xiàng)卡切換效果，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了js選項(xiàng)卡切換效果的具體代碼，供大家參考，具體內(nèi)容如下

實(shí)現(xiàn)思路：

1、首先獲取id元素。
2、for循環(huán)歷遍按鈕元素添加onclick事件。
3、排他思想，點(diǎn)擊按鈕時(shí)設(shè)置所有選項(xiàng)卡按鈕樣式為空，利用this關(guān)鍵字指定當(dāng)前選項(xiàng)卡獲得高亮樣式。
4、下面的多個(gè)div內(nèi)容塊以此類推。
