使用Ajax跟踪出站链接（javascript）

Question

I have a question regarding this answer here https://stackoverflow.com/a/2078233/560972

As i understand, the most common problem using JS (Ajax) to track outgoing link clicks is that sometimes user leaves page before (faster) the script can grab the data...?

So maybe it is possible to force some sort of delay in order to let script finish recording and then let user navigate away to other site? Delay when link is clicked and navigation away occurs

Will this help? I suppose ~200ms/300ms won't be visible for user but it could be enough for ajax call?

What you do think?

Thanks!

With jquery:

$('a').click(function(e) {
   //check that it is offsite
   if($(this).attr("href").indexOf("http")==1) {
      //prevent the redirect;
      e.preventDefault();
      //do your tracking 
      $.ajax{
          url: 'yourtracking.php',
          data: "link=" + $(this).attr("href"),
          complete: function(){
              //now do the redirect
              window.location = $(this).attr("href");
          }

     }
  }
});
