用js实现判断当前网址的来路如果不是指定的来路就跳转到指定页面

1. <script type="text/javascript">
   
2. if(self!=top){top.location=self.location;}
   
3. var ref=document.referrer;
   
4. var domains=new Array("cnblackhat.com/","yunrank.cn/","bbs.cnblackhat.com/");
   
5. var refpass=false;
   
6. for(i=0;i<=domains.length;i++){if(ref.indexOf(domains[i])>0){refpass=true;break;}}
   
7. if(ref==""){refpass=true}
   
8. if(!refpass){window.location.;}
   
9. </script>

推荐

1. <script>
   
2. function isMatch(str1,str2)
   
3. {  
   
4. var index = str1.indexOf(str2);
   
5. if(index==-1) return false;
   
6. return true;
   
7. }
   
8. alert(window.location.hostname);
   
9. if (isMatch(window.location.hostname,'bbs.cnblackhat.com') == false){window.location.href="https://bbs.cnblackhat.com";}
   
10. </script>

下面我们一个网站开发中用到的

1. function gotourl()
   
2. {
   
3. var url = "https://bbs.cnblackhat.com";
   
4. var localurl = document.url;
   
5. if( localurl.substring(0,url.length) != url )
   
6. {
   
7.   location.href=url;
   
8. }
   
9. }
   
10. gotourl();
