//公共方法
function getCookie(cname) {
    //读取cookies 
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
            var c = ca[i];
            while (c.charAt(0) == ' ') c = c.substring(1);
            if (c.indexOf(name) != -1) return c.substring(name.length, c.length);
         }
         return "";
    }

//name就是你想要拿的cookie的name;并将得到的cookie值赋给bbb
var bbb = getCookie('name');
