微信小程序动画之下拉刷新动画的具体代码,供大家参考,具体内容如下

微信小程序实现下拉刷新动画

简易的效果

下面放代码:

js:

var animation = wx.createanimation({})
var i = 1;
page({
 data: {
  donghua: true,
  left1: math.floor(math.random() * 250 + 1),
  left2: math.floor(math.random() * 250 + 1),
  left3: math.floor(math.random() * 250 + 1),
  left4: math.floor(math.random() * 250 + 1),
  left5: math.floor(math.random() * 250 + 1),
  left6: math.floor(math.random() * 250 + 1),
  left7: math.floor(math.random() * 250 + 1),
  left8: math.floor(math.random() * 250 + 1),
 },

 //动画
 donghua: function () {
  var that = this;
  settimeout(function () {
   animation.translatey(800).step({
    duration: 1600,
    timingfunction: 'ease'
   })
   that.setdata({
    ["animationdata" + i]: animation.export()
   })
   i++;
  }.bind(that), 200)
  if (i < 9) {
   settimeout(function () {
    that.donghua()
   }.bind(that), 200)
  } else {
   i = 0;
   animation.translatey(-800).step({
    duration: 10,

   })
   settimeout(function () {
    for (var y = 0; y < 9; y++) {
     that.setdata({
      ["animationdata" + y]: animation.export()
     })
     that.setdata({
      ["animationdata" + y + '.actions[0].animates[0].args[0]']: 0
     })
    }
   }.bind(that), 1500)

  }
 },
 onpulldownrefresh: function () {

  wx.shownavigationbarloading();


  this.donghua();



  wx.stoppulldownrefresh();
 },

})

wxml:

<!-- 动画 -->
<block wx:if="{{donghua}}">
 <view class='donghua'>
  <image bindtap='hua' style='left:{{left1}}px' animation="{{animationdata1}}" src='../../images/1.png'></image>
  <image bindtap='hua' style='left:{{left2}}px' animation="{{animationdata2}}" src='../../images/2.png'></image>
  <image bindtap='hua' style='left:{{left3}}px' animation="{{animationdata3}}" src='../../images/3.png'></image>
  <image bindtap='hua' style='left:{{left4}}px' animation="{{animationdata4}}" src='../../images/1.png'></image>
  <image bindtap='hua' style='left:{{left5}}px' animation="{{animationdata5}}" src='../../images/2.png'></image>
  <image bindtap='hua' style='left:{{left6}}px' animation="{{animationdata6}}" src='../../images/3.png'></image>
  <image bindtap='hua' style='left:{{left7}}px' animation="{{animationdata7}}" src='../../images/1.png'></image>
    <image bindtap='hua' style='left:{{left8}}px' animation="{{animationdata8}}" src='../../images/2.png'></image>
 </view>
</block>

wxss:

image{
 margin-top: -150rpx;
 width: 40rpx;
 height: 40rpx;
 margin-left: 5%;
 position: absolute;
 
}
