Jquery on click ads a variable to the link

My blog has its posts links. What I need is code that will do this: when a user clicks on a post link, a parameter will be added to the link which I'll 开发者_运维知识库use with a get function on the other page.

This is my link - link which is visible and indexed by google:

<a href="http://www.mysite.com/post1/">my post link</a>

When a user clicks on it, I need a way to add ?car=type to the link, http://www.mysite.com/post1/?car=type.

I'd like to do this with jQuery.

P.S.

I can't just add my car variable to the links in normal html, becouse Google will index them badly, the variables change every day and I'd get pages not found all over the serps.

Any idee? Ty!

Well...

$(document).ready(function() {
    $("a").click(function() {
       this.href += "?car=type";
    });
});

If you mark the desingated links in a way such as a class (say addType):

<a href="http://www.mysite.com/post1/" class="addType" >my post link</a>

you can do something like this on document load, no need to wait for click to do it:

$(function() {
   $("a.addType").attr("href",function() {return this + "?car=type";});
});
