微信小程序实现给循环列表添加点击样式实例

<view class="taga"> <view class="tag-title">标签</view> <view class="tag-box"> <view wx:for="{{taga}}" wx:key="id" wx:for-index="i"> <view class="taga-item {{currentItem==item.id?'active-tag':''}}" data-id="{{item.id}}" bindtap="tagChoose">{{item.name}}</view> </view> </view> </view>

 tagChoose:function(options){ var that = this var id = options.currentTarget.dataset.id; console.log(id) //设置当前样式 that.setData({ 'currentItem':id }) }
