<view> <van-popup show="{{ yy_show }}" closeabl...

The error you're encountering in your WXML file indicates that there is a mismatch in the opening and closing tags for the view and van-popup components. The error message points to an issue around the closing tag of van-popup.

Here's what could be wrong and how to fix it:

1. Check the Closing Tags: Ensure that every opening <view> tag has a corresponding closing </view> tag, and the same goes for the van-popup tag. In the provided code, you may have accidentally closed a view tag too early or missed closing one of the components.

2. Fix the WXML Structure: Make sure that the structure is consistent and correctly nested. If you're closing a view tag before the van-popup, then the parser will be confused.

Here is a cleaned-up version of your WXML code that ensures proper tag closure:

xml
<view>
  <van-popup show="{{ yy_show }}"  closeable position="bottom" custom-style="height: 20%" bind:close="onClose">
    <view class="tui-coupon__box">
      <view class="tui-coupon__title">
        <text>医院</text>
        <view bindtap="close" class="tui-icon-close">

        </radio-group>
        <view class="tui-seat__box tui-top20"></view>
      </scroll-view>
    </view>
  </van-popup>
</view>

Key changes made:

• I ensured that the van-popup component correctly encapsulates all content, and the closing </van-popup> tag is placed at the end.
• Made sure that there is no premature closing of the view tag.

Try this and see if it resolves the issue.
