jQuery toggle cookie function

Question

I have simple toggle (button switch) function here, but I don't know how to add cookie and how to remember position when users clicks on button.

Anyone can help me to add cookie here ?

$(document).ready(function(){ 
 $("a.switch_thumb").toggle(function(){
  $(this).addClass("swap"); 
  $("ul.display").fadeOut(100, function() {
  $(this).fadeIn(100).addClass("thumb_view"); 
     });
  },

function () {
 $(this).removeClass("swap");
 $("ul.display").fadeOut(100, function() {
 $(this).fadeIn(110).removeClass("thumb_view");
    });

}); 
});

check out this pluggin https://github.com/carhartl/jquery-cookie is very simple, after you include it you could just add a flag like

$.cookie('cookie_button', 'pressed'); //when pressed or
$.cookie('cookie_button', 'not_pressed'); //if is the case

Then check the cookie value when loading the page so you can remember the users last selection

Add this to ur head

jQuery.cookie = function (key, value, options) {

    // key and at least value given, set cookie...
    if (arguments.length > 1 && String(value) !== "[object Object]") {
        options = jQuery.extend({}, options);

        value = String(value);

        return (document.cookie = [

What about this? This will set the button_cookie to value 1 or 0 according to the fact, whether user clicked on button even or odd times

$(document).ready(function(){ 
    $("a.switch_thumb").toggle(
        function(){
            $(this).addClass("swap"); 
            $("ul.display").fadeOut(100, function() {
                $(this).fadeIn(100).addClass("thumb_view"); 
            });
            setCookie('button_pressed',!$(this).hasClass("swap"));
        },
        function () {
            $(this).removeClass("swap");
            $("ul.display").fadeOut(100, function() {
                $(this).fadeIn(110).removeClass("thumb_view");
            });
            setCookie('button_pressed',$(this).hasClass("swap"));
        }
    ); 
});

/**
 * implementation of setCookie function
 * this function creates only session cookie, can be amended so to use expires param
 */
function setCookie(name, value){
    document.cookie=name+'='+value;
}
