Load a javascript only for safari, and loading script for all browsers except safari

I have two scripts; script1.js & script2.js

I need script1.js to be included in all browsers except safari and script2.js to be included in only safary.

How can I do this?

 

Try this:

<script type="text/javascript">
  pattern = /safari/i;
  if(pattern.test(navigator.userAgent)){
    var head = document.getElementsByTagName("head")[0];

    var script = document.createElement("script");
    script.setAttribute("type", "text/javascript");
    script.setAttribute("src", "script2.js");

    head.appendChild(script);
  }else{
    var head = document.getElementsByTagName("head")[0];

    var script = document.createElement("script");
    script.setAttribute("type", "text/javascript");
    script.setAttribute("src", "script1.js");

    head.appendChild(script);
  }
  </script>
