The code is mostly correct, but there are a few minor issues and improvements that can be made:

1. The comments added to hide default values when dialogVisible is false are unnecessary and could cause confusion.
2. Consider removing or commenting out the commented-out lines with default values, unless they serve some specific purpose (e.g., debugging).
3. Ensure all necessary dependencies like v-loading, refs, and $t are properly imported and defined.
4. The rest of the logic appears to be correctly implemented.

Here's a slightly optimized version of the relevant part:

watch(dialogVisible, (bool) => {
  if (!bool) {
    form.value.dataset_setting = {
      search_mode: 'embedding',
      top_n: 3,
      similarity: 0.6,
      max_paragraph_char_number: 5000,
      no_references_setting: {
        status: 'ai_questioning',
        value: '{question}'
      }
    };
    noReferencesform.value.ai_questioning = defaultValue['ai_questioning'];
    noReferencesform.value.designated_answer = defaultValue['designated_answer'];
    
    // Optionally, you might want to reset any loading state here
    loading.value = false;
  } else {
    // Initialize form with new defaults or load existing data
  }
});

If you have more complex initialization logic for noReferencesform, it would need to be included within the else block. Make sure to adjust based on your full application structure and requirements.
