求助：集成TinyMCE时出现Uncaught ReferenceError: tinyMCE is not defined错误

Hey there! Let's tackle that Uncaught ReferenceError: tinyMCE is not defined error you're hitting when integrating TinyMCE. This is a super common issue, usually tied to how you're loading the editor's scripts or timing your code calls. Here are the most likely fixes to try:

1. Make sure TinyMCE loads before your initialization code

The biggest culprit here is trying to call tinyMCE before the editor's script has fully loaded. Always place the TinyMCE script tag above any code that interacts with it. For example:

<!-- Load TinyMCE first -->
<script src="https://cdn.tiny.cloud/1/YOUR_API_KEY/tinymce/6/tinymce.min.js" referrerpolicy="origin"></script>
<!-- Then your initialization code -->
<script>
  tinyMCE.init({
    selector: '#my-textarea'
  });
</script>

If you're using async or defer on the script tag, wrap your initialization in a callback that waits for the script to load. You can use the DOMContentLoaded event or TinyMCE's own loading hooks to ensure timing is right.

2. Verify your API key (if using the CDN)

If you're using the official TinyMCE CDN, a missing or invalid API key will cause the script to fail silently. Double-check that your script URL includes a valid key (you can get a free one from TinyMCE's official platform). A broken key means the editor never loads, hence the reference error.

3. Check for network or path issues

Open your browser's dev tools (F12) and head to the Network tab. Reload your page and look for the TinyMCE script—if it returns a 404, 403, or any error status, that means the script isn't loading at all. Fix the URL path (if using a local copy) or resolve any network restrictions blocking the CDN.

4. Watch for typos and variable consistency

Double-check that you're using the correct variable name: tinyMCE (capital M and C) is the official global, though TinyMCE also supports the lowercase tinymce alias. Mixing these up (e.g., writing tinymce.init() but referencing tinyMCE elsewhere) can trigger this error. Stick to one convention throughout your code.

5. Rule out script conflicts

If you have other scripts on the page, they might be overriding or interfering with the tinyMCE global variable. Test your TinyMCE integration in a clean, minimal HTML page with no other scripts. If it works there, gradually add back your other scripts to pinpoint the conflicting code.

Give these steps a shot—most of the time, this error boils down to a simple loading order or path issue. Let me know if you're still stuck after trying these!
