Ajax调用将click事件放入php变量以避免window.open（）方法

I have this jQuery scrip which counts the number of clicks on a certain div and then, at the second click, it redirects the user to a custom url. The script works and counts the clicks even if the user leaves the page.

function traffic(){
    var traffic = $('.model').data("traffic");
    if(traffic){
        var nbc = localStorage['nbc']||0;
        $('.model a').click(function(){
            localStorage['nbc'] = ++nbc;
            if(nbc%2==0){
                window.open(traffic, '_blank');
            }
        });
    }
} 

Now, I am a total newb with ajax (actually i do not know anything about it, I am a webmaster not a programer with an overdue deadline) and I need some help:

I need an ajax call that, on the time of the action, will send the second click into a php variable so I can use a code like the following (and avoid the "window.open" method which is in conflict with another script I use on the page):

   if($number_of_clicks == 2){
       echo 'my new link, a method which will save me from using window.open';
   } else {
       echo 'my ragular link';
   }

Can it be done?

UPDATE

Let me explain, my fault for not being clearer.

User enters my site and clicks on a normal link. Jquery stores that event and the user goes to an internal page.

When he hits the home button, ajax sends that event to a php variable, so I'll have $myvar=1.

Now I can change that certain link on my site with:

if($myvar == 1){
           echo 'my new link';
       } else {
           echo 'my ragular link';
       }

And now, when the user clicks on that link, he will go to the new link.

Hope I've been a little clearer.

Ty!

The only way to get a click to PHP is to just an AJAX request. EG:

$.get('/clickonce.php');

and then in PHP you could do:

<?php
$myvar = 1;
?>

But this wouldnt be perfect. The clickonce.php code will be called, but there is a delay since it's a new page request, so with slow internet/server responds it could be more then a few seconds before it is actually logged.

Considering that your window.open is conflicting with another script, which I assume is javascript, i would go for a javascript solution.

var clickedOnce = false;
function traffic(){
    var traffic = $('.model').data("traffic");
    if(traffic){
        var nbc = localStorage['nbc']||0;
        $('.model a').click(function(){
            localStorage['nbc'] = ++nbc;
            if(nbc%2==0){
                window.open(traffic, '_blank');
            } else {
                clickedOnce = true;
            }
        });
    }
} 

now in your other javascript script you can check for if (!clickedOnce) { //do something }

Well, you can simply make an AJAX get request using jQuery.

$.get('/your.php', function(url) {
     // value echoed by your php page will be available in the url variable passed into this function.
     // You can do what you want with it.
     alert(url);
});
