JQUERY insert string in relative pretty url

Question

I like to insert a string with Jquery only in case of "some" relative pretty url.

the string that must be inserted contains a value of '/1' or '/2' or '/3'

So a url like:

<a href="/whatever"> becomes 
<a href="/1/whatever"> or <a href="/2/whatever"> etc.

But a url like

<a href="/1/whatever"> or 
<a href="/2/whatever"> must keep unchanged

All examples below must keep unchanged.

/whatever/whatever
/whatever/whatever/whatever

<img src="/img.png">
<img src="/whatever/img.png">
<img src="/whatever/whatever/img.png">
<img src="http://whatever.com/img.png">
<img src="http://whatever.com/whatever/img.png">

<a href="http://whatever.com></a>
<a href="http://whatever.com/whatever.whatever></a>
<a href="http://whatever.com/whatever/whatever.whatever></a>

Hi try the following code :

$(document).ready(function(){
      $ ("a").each(function(){
         var url = $(this).attr("href"),
         count = (url.match(/\//g) || []).length;
         if(count == 1)
         {
             var cookieValue; //set your cookie value in this variable
             $(this).attr("href","/"+cookieValue + $(this).attr("href"));
         }
      });

      $ ("img").each(function(){
        var url = $(this).attr("src"),
            count = (url.match(/\//g) || []).length;
        if(count == 1)
        {
            var cookieValue; //set your cookie value in this variable
            $(this).attr("src","/" + cookieValue + $(this).attr("src"));
        }
    });
  });
