本文相关跳坑指南:跳坑《一百三十四》animation动画相关问题说明
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 class="show-iconView">
-
<image src="{{src}}" class="show-iconImage" 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!
