    这是主要的html文件：

    <import src="./dialog/dialog.wxml"/>
     
    <template is="dialog" data="{{...qrCodeModalInfo}}"/>
     
    <view class="full-container">
      <scroll-view wx:if="{{currentTab==2}}" class="scroll-content" scroll-y="true">
        <import src="./myCard/myCard.wxml" />
        <template is="myCard" data="{{...myCards}}" />
      </scroll-view>
      <scroll-view wx:if="{{currentTab==1}}" class="scroll-content" scroll-y="true">
        <import src="./recommendCard/recommendCard.wxml" />
        <template is="recommendCard" data="{{...recommendCards}}" />
      </scroll-view>
      <view class="footer">
        <view class="button-footer {{currentTab == 1 ? 'button-footer-selected' : ''}}" bindtap="chooseRecommend">
          <view class="botton-footer-left button-footer-wrapper">

            我的卡券
