taro 动态新增表单不生效

<AtPage>
        <AtTitle>店铺基础信息</AtTitle>
          <View className={styles.add} onClick={this.addShop.bind(this)}>
            <AtIcon value='add' color='#2163E0' size={15} /> 新增</View>
        <br />
          {
            this.state.shopArr.map((item, index)=> {
              return (
                <AtBoxWrap>
                  <AtInput
                    name='shopName'
                    value={item.shopName}
                    title='档主姓名'
                    type='text'
                    maxLength='30'
                    placeholder='请填写'
                    onChange={this.handleChange.bind(this, 'shopName')}
                  />
                  <AtInput
                    name='shopUrl'
                    value={item.shopUrl}
                    title='档口编号'
                    type='text'
                    maxLength='30'
                    placeholder='请填写'
                    onChange={this.handleChange.bind(this, 'shopUrl')}
                  />
                </AtBoxWrap>
              )
            })
          }

      </AtPage>

addShop() {
    const item = {
      settledType: '',
      settledPlatfoem: '',
      shopName: '',
      shopUrl: '',
      operatingLicense: '',
      settledFullName: '',
      isBusinessLicense: '',
      id: this.state.shopArr.length
    }
    this.state.shopArr.push(item)
    console.log(this.state.shopArr)
  }

点击新增的时候 ，界面上图形不会显，我想在点击新增的时候，会在界面上显示文本框，点击几次就加几个？

Answer 1

this.setState({
  shopArr: this.state.shopAr.concat(item)
})
