在JavaScript中指定引用页

Posted 2021-02-23

This script informs your visitor that a given page may be reached only from the page that you specify. Paste this code before the ending tag on the page:

<script type="text/javascript">
   var allowed_referrer = "http://www.yourdomain.com/referring_page_name.html"; 
   if(document.referrer.indexOf(allowed_referrer) == -1){
      alert("You can access this page only from " + allowed_referrer);
      window.location = allowed_referrer;
   }
</script>
