Apostrophe 2是否支持条件字段？相关功能文档咨询

Great question—let's tackle this head-on!

First, the core answer: Apostrophe 2 does not include built-in support for conditional fields (the ability to show/hide fields based on the value of another field) out of the box.

You’re correct to note that discussions about this feature exist in the apostrophecms-legacy repository, but these are mostly historical community conversations or unofficial workarounds. There is no official, maintained documentation for conditional fields in Apostrophe 2 from the core team.

If you need this functionality for your project, you’ll have to implement it using custom frontend JavaScript. Here’s a simplified example of how you might approach this:

// Add this to your module's editor.js file
apostrophe('ready', function() {
  // Replace with your actual field selectors
  const triggerField = document.querySelector('[name="your-trigger-field-name"]');
  const targetFieldContainer = document.querySelector('[data-field="your-target-field-name"]');
  
  if (triggerField && targetFieldContainer) {
    // Define the toggle logic
    const toggleFieldVisibility = () => {
      // Adjust the condition to match your use case
      targetFieldContainer.style.display = triggerField.value === 'specific-value' ? 'block' : 'none';
    };
    
    // Set initial visibility when the editor loads
    toggleFieldVisibility();
    // Update visibility when the trigger field changes
    triggerField.addEventListener('change', toggleFieldVisibility);
  }
});

Just a heads-up: these custom workarounds aren’t officially supported, so you’ll need to maintain them as Apostrophe 2 receives updates.
