我正在使用 jquery-cookie 库用 JQuery 创建 cookie。如何更新 cookie 的值？我需要它创建新的 cookie，如果 cookie 存在来更新它。我怎样才能做到这一点？我得到的代码：
v.on('click', function(){
var d = $(this).attr('role');
if(d == 'yes')

glas = 'koristan.'
}else {
glas = 'nekoristan.'
};
text = 'Ovaj komentar vam je bio ' + glas;
//This part here create cookie
if(id_u == 0){
$.cookie('010', id + '-' + d);
}
$.post('<?php echo base_url() ?>rating/rat_counter', {id : id, vote : d, id_u : id_u}, function(){
c.fadeOut('fast').empty().append('<p>' + text).hide().fadeIn('fast');

To update a cookie all you need to do is create a cookie with the same name and a different value.
要更新 cookie，您需要做的就是创建一个具有相同名称和不同值的 cookie。

To append your new value to the old...
要将新值附加到旧值...
//Im not familiar with this library but
//I assume this syntax gets the cookie value.
var oldCookieValue = $.cookie('010');
//Create new cookie with same name and concatenate the old and new desired value.
$.cookie('010', oldCookieValue + "-" + id);
