怎么获取不到slot 中input的name和value?

<form report-submit=‘true’ bindsubmit=‘butSubmit’>

 <button class=‘bnt’ form-type=‘submit’ bindgetuserinfo=“getUserInfo” lang=“zh_CN” bindgetphonenumber=“getPhoneNumber” open-type=“{{openType}}”>

   <slot name=“but”>slot>

 button>

form>

  <authorizeView bind:onBut=“onNext” >

      <view slot=“form” class=“authorizeView”>

        <view class=‘item’>

          <view class=‘name’>球队名称</view>

          <input bindinput=“onGroupName” name=“group_name” maxlength=“{{15}}” placeholder=‘取个好听的名字吧（15个字以内)’ placeholder-class=‘inputPlaceholder’></input>

        </view>
