小程序循环点击使用js添加css样式

//wxml
<block wx:for="{{Listsimg}}" wx:key='unique'>
    <block wx:if="{{index == clickId}}">
       <view class="img" style="border:{{border}};box-shadow:{{borders}}" id="{{index}}" bindtap="imgList" data-data="{{item}}">
           <image src="{{item.imgList}}" />
       </view>
    </block>
    <block wx:else>
       <view class="img" id="{{index}}" bindtap="imgList" data-data="{{item}}">
           <image src="{{item.imgList}}" />
       </view>
    </block>
</block>
//js
 data: {
      Listsumg: [
        {
          imgList: '../../images/1.jpg'
        },
        {
          imgList: '../../images/2.jpg'
        },
        {
          imgList: '../../images/3.jpg'
        }
      ],
      border:'',
      clickId:'',
      borders:''
},
imgList:function(e){
    console.log(this.data.imgLists[e.currentTarget.id])
    this.setData({
       border:"1rpx solid #eee",
       borders:'10rpx 10rpx 10rpx rgba(141, 161, 167, 0.9);',
       clickId:e.currentTarget.id
    })
 },
