微信小程序 连续旋转动画
一、.js中封装旋转动画方法
添加animation属性
data:{ animation:''" }
改变animation的值(官网提供角度范围是-180~180,但是我发现角度越大会一直旋转)
onShow: function() { console.log('index---------onShow()') this.animation = wx.createAnimation({ duration: 1400, timingFunction: 'linear', // "linear","ease","ease-in","ease-in-out","ease-out","step-start","step-end" delay: 0, transformOrigin: '50% 50% 0', success: function(res) { console.log("res") } }) }, rotateAni: function (n) { console.log("rotate=="+n) this.animation.rotate(180*(n)).step() this.setData({ animation: this.animation.export() }) },
二、在.wxml中需要的控件上添加animation属性
<view> <image src="https://www.jb51.net/{{src}}" animation="{{animation}}" mode="scaleToFill"></image> </view>
三、连续动画需要添加定时器
this.interval = setInterval所传参数每次++i就行!
