如何添加cookie會話記住隱藏的碼頭狀態？

Question

如何將Cookie代碼添加到我目前擁有的代碼中？我一直在閱讀，但我不是最好的與jQuery。

http://jsfiddle.net/k9vAJ/

代碼：

$(document).ready(function() { 
    var visible = true; 
    $("#docktoggle").on('click', function() { 
     $('.dock') 
      .animate({ width: visible ? 0 : 980 }, "slow") 
      .css({ display: visible ? "none" : "" }) 
      .css({ width: visible ? "none" : "100% !important" }); 
     visible = !visible; 
    }); 
}); 

$(function(){ 
    $(".img-swap").live('click', function() { 
     if ($(this).attr("class") == "img-swap") { 
      this.src = this.src.replace("_on","_off"); 
     } 
     else { 
      this.src = this.src.replace("_off","_on"); 
     } 
     $(this).toggleClass("on"); 
    }); 
});

你可能想使用一個jQuery插件，我認爲也有一定的參考文件。我知道這一點，因爲我已經將它用於jstree jQuery插件，因爲它完全包裝了它。該插件處理與爲cookie定義的原型進行交互，最終保存該cookie，如果沒有誤入瀏覽器。
