今天接到一个小程序优化需求，要实现一个点击的动画效果
考虑实现方法，使用css的transition属性来进行实现，点击的时候给css新增一个active属性，就能实现这个效果了
// html
<view class="list-box">
<view class="list {{item.check ? 'active' : ''}}" wx:for="{{listOne}}" data-id="{{item.id}}" wx:key="index" bindtap="bindClick">
<view class="point">
<image src="../../../img/sure-icon.png" mode="widthFix"/>
</view>
{{item.name}}
</view>
</view>// js
data: {
listOne: [
{ id: 1, name: '弱音频', check:false},
{ id: 2, name: '中音频', check:false},
{ id: 3, name: '强音频', check:false}
]
}
// 点击方法
bindClick (e) {
let id = e.currentTarget.dataset.id
let listOne = this.data.listOne.map(item => {
if(item.id == id ){
item.check = true
// 选中以后需要执行的方法
}else {
item.check = false
}
return item
})
this.setData({listOne})
},// css 主要css是在active的位置，其余的可以根据设计稿样式自己改
.list-box{
