How is this different from a basic frame redirect?

A basic script just asks 'Am I in a frame?'. This script asks 'Am I in MY frame?'. It checks the name or URL of the parent window to prevent being framed by external sites.

What happens if the parent frameset name doesn't match?

The script will treat it as if the page is unframed and trigger a redirect to your primary index or frameset loader.

Does this work with nested framesets?

Yes. You can target specific levels of the window hierarchy (parent vs top) to ensure the nested structure is intact.

Check Frames Page Script

Verify your site's structure with precision. This advanced script doesn't just check for the presence of a frame; it validates that the parent window is your specific frameset, preventing your content from being improperly embedded elsewhere.

Technical Insight

This script uses the window.name or document.referrer properties to identify the parent. It is the ideal solution for developers managing complex multi-frame portals.

Copy the Script

<script>
  // Replace 'main_frameset' with the name of your frameset window
  if (window.parent.name != 'main_frameset') {
    window.location.href = "index.html";
  }
</script>

Note: Ensure you have named your frameset in your <frame> or <iframe> tags using the 'name' attribute for this script to function.

Frequently Asked Questions
