我试图删除API cookie并将其重置为一个新的对象，但是当我为它添加另一个API cookie。

I am trying to remove the API cookie and reset it to a new object however when i do that it adds another API cookie for me.

下面是我的代码，我使用cookies.js从这链接

Below is my code i am using cookies.js from this link

   var dataPromise = get_api_token_refresh_token(refresh_token).done(handleData).fail(failHandler);
    dataPromise.success(function (api_token) {
   var something = docCookies.removeItem('API');
        console.log(something);
        docCookies.setItem("API", JSON.stringify(api_token));
   });

我的情况发生了什么：

注意：Cookie是在asp.net mvc代码

NOTE: The cookies are being set in the asp.net mvc code

string token_string = "";
                if (loginResult.User != null)
                {
                    //make a call to the REST api authentication method and get accesstokens
                    token_string = OAuthHelper.getTokenFromAPIServer(api_auth_username, api_auth_password);
                    if (collection["Check"] != null)
                    {
                        check = collection["Check"];

                        if (check == "on")
                        {
                            FormsAuthentication.SetAuthCookie(loginResult.User.Name, true);
                            Response.Cookies[Constants.Cookies.USERNAME].Value = loginResult.User.Email;
                            Response.Cookies[Constants.Cookies.PWD].Value = savePassword;//loginResult.User.Password;
                            Response.Cookies[Constants.Cookies.USERNAME].Expires = DateTime.Now.AddDays(10);
                            Response.Cookies[Constants.Cookies.PWD].Expires = DateTime.Now.AddDays(10);


                        }
                    }
                    else
                    {
                        FormsAuthentication.SetAuthCookie(loginResult.User.Name, false);
                        Response.Cookies[Constants.Cookies.USERNAME].Value = string.Empty;
                        Response.Cookies[Constants.Cookies.PWD].Value = string.Empty;
                    }
                    Response.Cookies[Constants.Cookies.API].Value = token_string;

推荐答案

您可以使用 jquery.cookie 插件。非常易于使用：

you can use jquery.cookie plugin. It's very easy to use:

删除Cookie：

// Returns true when cookie was successfully deleted, otherwise false
$.removeCookie('name'); // => true
$.removeCookie('nothing'); // => false

// Need to use the same attributes (path, domain) as what the cookie was written with
$.cookie('name', 'value', { path: '/' });
// This won't work!
$.removeCookie('name'); // => false
// This will work!
$.removeCookie('name', { path: '/' }); // => true

创建会话cookie：

Create session cookie:

$.cookie('name', 'value');

建立到期的Cookie，7天后：

Create expiring cookie, 7 days from then:

$.cookie('name', 'value', { expires: 7 });

创建有效的cookie，整个网站都有效：

Create expiring cookie, valid across entire site:

$.cookie('name', 'value', { expires: 7, path: '/' });

阅读cookie：

$.cookie('name'); // => "value"
$.cookie('nothing'); // => undefined

阅读所有可用的Cookie：

Read all available cookies:

$.cookie(); // => { "name": "value" }
