入行1个月开发者求助：误触Start debugging后恢复HTML代码及回退代码提交

Hey there! As someone who's just 1 month into development, it totally makes sense to feel flustered when unexpected stuff like this pops up—no worries, let's break this down and fix it together.

第一步：先解决误触Start Debugging后的代码混乱问题 #

First, let's rule out the most common scenarios:

• 只是编辑器显示错乱？：Sometimes when you start debugging, editors might throw temporary display glitches like offset highlighting or weird code folding, but your actual file isn't modified. Just click the red stop button in the debug panel to end the session, then refresh your editor (or restart it) — your code should go back to normal.
• 代码真的被意外修改了？：If you confirm the file content is actually messed up, try the undo shortcut first: press Ctrl+Z (Windows/Linux) or Cmd+Z (Mac) to step back through recent actions until you get to your original code.

第二步：将代码回退到原始源码状态的方法 #

We've got two scenarios here, depending on whether you're using version control:

情况1：你已经在用Git（版本控制工具） #

If your project has a Git repo set up, rolling back is straightforward:

1. Open your editor's terminal, run git status to check current file changes.
2. To undo all uncommitted changes and restore everything to the last committed source state:

   git restore .
   

3. If you've already made a bad commit and need to roll back to a specific history version:
   • First run git log to find the commit hash (the long string of letters/numbers) of your desired source version.
   • Then run:

     git reset --hard <your-commit-hash>
     

     Note: This will wipe all uncommitted changes, so make sure you don't need them before running it!

情况2：没用到版本控制工具 #

If you haven't started using Git yet, you still have options:

• Editor local history: Most popular editors (like VS Code, Sublime Text) save local file histories. For VS Code, right-click your messed-up HTML file, select "Local History" -> "Show History" — you'll see all past versions of the file. Pick your source version and click "Restore".
• System file backups: If you have system backups enabled (like Windows File History or Mac Time Machine), you can use those to recover the original file version.

A quick tip for new devs: Getting into the habit of using Git early on is like having a code "time machine" — it'll save you from so many panic moments like this in the future!
