如何在外部网站上基于引荐来源使用javascript重定向页面和js? [英] How to redirect page and js using javascript on external domain based on referer?

问题描述

我有一些站点mysite1.com，mysite2.com，.... mysiten.com

I have some sites mysite1.com, mysite2.com,....mysiten.com

所有mysite1-n.com在myexternalsite.com/mainfile.js

我想要

如果(mysite1-n.com)位访问者来自www.google.com，则将重定向到welcome.com

if (mysite1-n.com) visitors come from www.google.com then will redirect to welcome.com

如果(mysite1-n.com)位访问者来自www.yahoo.com，则将重定向到welcome2.com

if (mysite1-n.com) visitors come from www.yahoo.com then will redirect to welcome2.com

如果(mysite1-n.com)位访问者来自www.anotherdomain.com，则将在myexternalsite.com/file1.js上调用javascript并使用此脚本进行工作

if (mysite1-n.com) visitors come from www.anotherdomain.com then will call javascript on myexternalsite.com/file1.js and working using this script

如果(mysite1-n.com)位访问者来自书签，则将在myexternalsite.com/file2.js上调用javascript并使用此脚本进行工作

And if (mysite1-n.com) visitors come from bookmark then will call javascript on myexternalsite.com/file2.js and working using this script

我应该在myexternalsite.com/mainfile.js上使用哪种脚本?

What sort of script should I be using on myexternalsite.com/mainfile.js ?

谢谢

推荐答案

基本上，您应该检查document.referrer值和document.location.href来实现所需的功能.带有一堆正则表达式可以轻松解决问题.

basically you should check for document.referrer value and the document.location.href to do achieve what you want. This with a bunch of regexp should do the trick easily.

例如:

if( document.location.href.match(/^https?:\/\/mysite1-n.com/) ){
  if( document.referrer.match(/google.com/) ){
    window.location = 'http://welcome.com';
  }
  var s = document.createElement('script');
  s.src = 'myexternalsite.com/mainfile.js';
  document.head.appendChild(s);
}

以此类推
