本文实例为大家分享了微信小程序实现3D轮播图效果的具体代码,供大家参考,具体内容如下

首先上一下效果图:

微信小程序实现3D轮播图效果(非swiper组件)

 在做的时候首先想到的是用swiper组件但是发现swiper组件放进去图片的时候会没有3d的效果,原因是swiper组件自带的style属性限制了3d效果所需要的属性,所以单独写了一个组件。

index.html

<view class='page-con'>
  rotate.wxml
  <view class='stage'>
    <view class='wrapper' bindtouchstart='start' bindtouchend='end'>
      <block wx:for='{{swiperList}}'>
        <image class='imgBasic {{index === 0 "" : "fold"}} {{item.active ""}}' src='{{item.imgsrc}}' data-index='{{index}}'></image>
      </block>
    </view>
    <view class='dots'>
      <block wx:for='{{swiperList}}' wx:key='unique'>
        <view data-i='{{index}}' bindtap='fn' class='dot {{index === currentImageIndex "active" : ""}}'></view>
      </block>
    </view>
  </view>
</view>

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!

昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。

这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。

而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
