今日分享-一个摆动的弹框效果代码

1、废话不多说，先看效果

2、实现原理

运用常见的动画属性 animation、keyframes 等CSS3属性实现。

3、具体实现代码

HTML【wxml】

<view class="box" catchtap="show">弹出一个弹框</view>
<view class="codeBox" hidden="{{isShow}}" catchtap="hide">
  <view id="hide">
    <image src="https://s21.ax1x.com/2024/04/29/pkFAzkD.jpg" />
  </view>
</view>

CSS【wxss】

page{
  background: #000;
  background: radial-gradient(#222, #000);
  padding-bottom: 100rpx;
}
.box {
  width: 199px;
  text-align: center;
  border: 1px solid #DCDCDC;
  background: no-repeat center center;
  background-color: rgba(204, 217, 220, .1);
  background-size: 45px;
  transition: all .3s;
  cursor: pointer;
  overflow: hidden;
  height: 28px;
  line-height: 28px;
  opacity: .5;
  border-radius: 14px;
  color: #fff;
}

.box:hover {
  border: 1px solid #008000;
  background-color: rgba(177, 211, 220, 0.5);
}

@keyframes show {
  0% {
    transform: rotateX(90deg);
  }

  8% {
    opacity: 1;
    transform: rotateX(-60deg);
  }

  18% {
    opacity: 1;
    transform: rotateX(40deg);
  }

  34% {
    opacity: 1;
    transform: rotateX(-28deg);
  }

  44% {
    opacity: 1;
    transform: rotateX(18deg);
  }

  58% {
    opacity: 1;
    transform: rotateX(-12deg);
  }

  72% {
    opacity: 1;
    transform: rotateX(9deg);
  }

  88% {
    opacity: 1;
    transform: rotateX(-5deg);
  }

  96% {
    opacity: 1;
    transform: rotateX(2deg);
  }

  100% {
    opacity: 1;
  }
}

.codeBox {
  z-index: 1;
  perspective: 400px;
  position: absolute;
  margin: auto;
  width: 200px;
  height: 200px;
}

.codeBox view {
  width: 200px;
  height: 200px;
  background: #fff no-repeat center center;
  background-size: 190px;
  border-radius: 6px;
  box-shadow: 0 2px 7px rgb(0 0 0 / 30%);
  transition: all 1s ease-in-out;
  transform-style: preserve-3d;
  transform-origin: center center;
  overflow: hidden;
  opacity: 0;
  animation: show 3s ease-in-out 0s 1 normal forwards;
  -webkit-animation: show 3s ease-in-out 0s 1 normal forwards;
}

image {
  width: 200px;
  height: 200px;
}

.hide {
  animation: hide .5s ease-in-out 0s 1 normal forwards;
  -webkit-animation: hide .5s ease-in-out 0s 1 normal forwards;
}

@keyframes hide {

  20%,
  50% {
    transform: scale(1.08, 1.08);
    opacity: 1;
  }

  100% {
    opacity: 0;
    transform: rotateZ(40deg) scale(0.6);
  }
}

JS

Page({
  data: {
    isShow: true,
    a: {},
  },
  show() {
    this.setData({
      isShow: false
    })
  },
  hide() {
    this.setData({
      isShow: true
    })
  }
})

注：【这里代码片段实际应用于微信小程序，若在其他框架使用，道理是一样的，稍微改改即可使用】

4、实现简单，代码片段复制粘贴，即可预览效果体验效果。最后，贴一下自己的小程序，喜欢可以扫码查看更多...
