自动返回上一URL失败：meta refresh调用history.back()报错求助

Got it, let's tackle this issue head-on. Modern browsers block meta refresh from redirecting to javascript: URLs as a security measure—this is exactly why you're seeing that "Refused to refresh" error. Here are two reliable solutions to get the "go back" behavior working:

Solution 1: Use JavaScript Directly (Recommended) #

Ditch the meta tag entirely and use a simple script to handle the delayed back navigation. This avoids the browser's security restriction and gives you more control over edge cases:

<script>
  // Wait 2 seconds, then navigate back to the previous page
  setTimeout(() => {
    window.history.back();
    
    // Optional: Add a fallback if there's no browsing history to go back to
    if (!window.history.length) {
      window.location.href = "/your-fallback-page.html"; // Replace with your actual fallback URL
    }
  }, 2000);
</script>

This approach is straightforward, widely supported, and lets you handle scenarios where the user landed directly on your page (with no prior browsing history) instead of hitting a dead end.

Solution 2: Intermediate Page Workaround (If You Must Use Meta Tags) #

If you have a specific constraint that requires using a meta tag, you can set up a simple intermediate page to handle the back navigation:

1. Create a page named go-back.html and add the JavaScript snippet from Solution 1 to it.
2. Update your original meta tag to point to this intermediate page:

<meta http-equiv="refresh" content="2; url=/go-back.html">

This is a bit more roundabout, but it works if you're stuck using meta refresh for some reason.

Quick Tip #

Always test the fallback behavior! If a user arrives at your page via a direct bookmark or link, history.back() won't have anywhere to go—so adding that fallback URL ensures they land somewhere useful instead of staying on the same page.
