The Bug in 30 Seconds

Problem: Edit modal closes immediately after opening

Cause: Vue event propagation - tap events bubble from action buttons to modal-mask's close handler

Solution: Add .stop modifier to prevent event bubbling

Impact: Users can now edit card types successfully


What Was Changed

File: packages/app/src/pages/admin/card-types.vue

Three lines modified:

- <view class="ct-action-btn edit-btn" @tap="openEdit(ct)">
+ <view class="ct-action-btn edit-btn" @tap.stop="openEdit(ct)">

- <view class="ct-action-btn toggle-btn" @tap="toggleActive(ct)">
+ <view class="ct-action-btn toggle-btn" @tap.stop="toggleActive(ct)">

- <view class="ct-action-btn delete-btn" @tap="confirmDelete(ct)">
+ <view class="ct-action-btn delete-btn" @tap.stop="confirmDelete(ct)">

Why It Works

The .stop modifier calls event.stopPropagation(), which prevents the tap event from bubbling to parent elements. This prevents the modal-mask's close handler from being triggered.

Event flow with fix:

  1. User taps action button ✓
  2. Event handler executes (edit/toggle/delete) ✓
  3. Event propagation is stopped ✗ (no bubbling)
  4. Modal-mask close handler is NOT triggered ✓
  5. Modal stays open ✓

Testing Instructions

Quick Test

  1. Go to Admin → Card Types
  2. Click any [编辑] (Edit) button
  3. Modal should open and stay open
  4. Edit a field and click [确认] (Confirm)
  5. Changes should save

Message:     fix(admin): prevent edit modal from closing immediately on tap

             Fix the card types management edit modal that was closing 
             immediately after opening due to event propagation. Added 
             .stop modifier to all action button tap handlers (edit, toggle, 
             delete) to prevent bubbling to parent modal-mask element.

             - Changed @tap="openEdit(ct)" to @tap.stop="openEdit(ct)"
             - Changed @tap="toggleActive(ct)" to @tap.stop="toggleActive(ct)"
             - Changed @tap="confirmDelete(ct)" to @tap.stop="confirmDelete(ct)"

             This fixes the bug where the edit modal would open and close in 
             the same event cycle, making it impossible to edit card types.

Technical Deep Dive

Problem Pattern

This is a classic Vue event propagation issue that occurs when:

  1. List items have action buttons
  2. Tap handlers on buttons trigger state changes
  3. Modal appears as overlay
  4. Modal-mask has a tap handler to close
  5. Event bubbles from button → card → list → modal-mask

Solution Pattern

The fix is to add .stop modifier to any event handler that triggers state changes that render overlays:

<!-- Before: Event bubbles to parent handlers -->
<button @tap="openModal(item)">Edit</button>

<!-- After: Event stops propagating -->
<button @tap.stop="openModal(item)">Edit</button>

Why This Is Safe

  • .stop only prevents propagation, not default behavior
  • Event still executes on the clicked element
  • All three buttons work independently
  • No side effects or unexpected behavior
  • Follows Vue best practices
