Animation:

wx.createAnimation(OBJECT)

Create an animation instance animation. Call the instance's methods to describe the animation. Finally, the animation data is exported through the export method of the animation instance and passed to the animation property of the component.

Note: The export method will clear the previous animation operation after each call

OBJECT parameter description:

var animation = wx.createAnimation({
 transformOrigin: "50% 50%",
 duration: 1000,
 timingFunction: "ease",
 delay: 0
})

animation

The animation instance can call the following method to describe the animation. After the call is completed It will return itself and support chain call writing.

Style:

Rotation:

Scale:

Offset:

Tilt:

Matrix transformation:

Animation queue

After calling the animation operation method, call step() to indicate the completion of a group of animations. You can call any number of animation methods in a group of animations. All animations in a group of animations will start at the same time, and will not start until a group of animations is completed. Next set of animations. step can pass in a configuration parameter similar to wx.createAnimation() to specify the configuration of the current group animation.

Example:

<view animation="{{animationData}}"   style="max-width:90%"></view>

Page({
 data: {
  animationData: {}
 },
 onShow: function(){
  var animation = wx.createAnimation({
   duration: 1000,
    timingFunction: 'ease',
  })
 
  this.animation = animation
 
  animation.scale(2,2).rotate(45).step()
 
  this.setData({
   animationData:animation.export()
  })
 
  setTimeout(function() {
   animation.translate(30).step()
   this.setData({
    animationData:animation.export()
   })
  }.bind(this), 1000)
 },
 rotateAndScale: function () {
  // 旋轉(zhuǎn)同時放大
  this.animation.rotate(45).scale(2, 2).step()
  this.setData({
   animationData: this.animation.export()
  })
 },
 rotateThenScale: function () {
  // 先旋轉(zhuǎn)后放大
  this.animation.rotate(45).step()
  this.animation.scale(2, 2).step()
  this.setData({
   animationData: this.animation.export()
  })
 },
 rotateAndScaleThenTranslate: function () {
  // 先旋轉(zhuǎn)同時放大，然后平移
  this.animation.rotate(45).scale(2, 2).step()
  this.animation.translate(100, 100).step({ duration: 1000 })
  this.setData({
   animationData: this.animation.export()
  })
 }
})
