jQuery滾動(dòng)切換，如此白菜效果你會(huì)信手拈來嗎

一個(gè)陰雨綿綿的天氣，再來跟大家分享一個(gè)jQuery小效果 - 滾動(dòng)切換效果，希望大家看后有所收獲，我也是剛開始摸索。

看圖說話：

不管寫什么效果必不可少的是html+css布局

該效果主要應(yīng)用點(diǎn)是jQuery的基本語法、選擇器以及一些方法的使用

主要是思路是a錨點(diǎn)的使用，當(dāng)滾動(dòng)頁面的時(shí)候去匹配html頁面中的a錨點(diǎn)，

其次是要獲取滾動(dòng)條滾動(dòng)高度以及每一個(gè)item元素的偏移量，對比匹配完成給當(dāng)前添加cur類。

想要源碼的寶寶們可以加我Q群：142991222，不見不散。小寶也需要跟更多伙伴們交流溝通以及學(xué)習(xí)更多新GET！

各位老鐵，大家好！

今天俺給大兄弟、大妹子們帶來的是 jQuery全屏焦點(diǎn)圖滑動(dòng)切換源碼

全屏滑動(dòng)，屬于暗黑炫酷系列！(適合高科技產(chǎn)品的展示)

若是想要文件源碼，請看評論區(qū)！

廢話不多說，上源碼！

CSS源碼：
