想做一個全屏滾動的效果，于是在網上找了一個差不多的例子，但是覺得有些地方不是很好，于是改進了一下；
先給大家展示下效果圖，感覺不錯，請參考實例代碼。
代碼：
wxml:
<!-- 第一頁 -- > <view id='hook1' class="section section01 {{scrollindex==0?'active':''}}" style='background:red' bindtouchstart="scrollTouchStart" bindtouchmove='scrollTouchMove' bindtouchend="scrollTouchEnd"> <view class='cont'> <view class='cont-body'> <view>one</view> </view> </view> </view> <!-- 第二頁 --> <view id='hook2' class="section section02 {{scrollindex==1?'active':''}}" style='background:pink' bindtouchstart="scrollTouchStart" bindtouchmove='scrollTouchMove' bindtouchend="scrollTouchEnd"> <view class='cont'> <view class='cont-body'> <view>two</view> </view> </view> </view> <!-- 第三頁 --> <view id='hook3' class="section section03 {{scrollindex==2?'active':''}}" style='background:blue' bindtouchstart="scrollTouchStart" bindtouchmove='scrollTouchMove' bindtouchend="scrollTouchEnd"> <view class='cont'> <view class='cont-body'> <view>three</view> </view> </view> </view> <!-- 第四頁 --> <view id='hook4' class="section section04 {{scrollindex==3?'active':''}}" style='background:green' bindtouchstart="scrollTouchStart" bindtouchmove='scrollTouchMove' bindtouchend="scrollTouchEnd"> <view class='cont'> <view class='cont-body'> <view>foure</view> </view> </view> </view>wxss:

以上所述是小編給大家介紹的微信小程序功能之全屏滾動效果的實現代碼，希望對大家有所幫助，如果大家有任何疑問請給我留言，小編會及時回復大家的。在此也非常感謝大家對武林網網站的支持！
