你可以使用我的cookie ES模块获取/设置/删除cookie。

用法:

在你的head标签中，包括以下代码:

<script src="https://raw.githack.com/anhr/cookieNodeJS/master/build/cookie.js"></script>

or

<script src="https://raw.githack.com/anhr/cookieNodeJS/master/build/cookie.min.js"></script>

现在你可以使用window了。Cookie用于在网页中存储用户信息。

cookie.isEnabled ()

您的网络浏览器是否启用了cookie ?

returns {boolean} true if cookie enabled.

例子

if ( cookie.isEnabled() )
    console.log('cookie is enabled on your browser');
else
    console.error('cookie is disabled on your browser');

饼干。集合(名称，值)

设置一个饼干。

name: cookie name.
value: cookie value.

例子

cookie.set('age', 25);

饼干。get(name[， defaultValue]);

吃块饼干。

name: cookie name.
defaultValue: cookie default value. Default is undefined.
returns cookie value or defaultValue if cookie was not found

Example

var age = cookie.get('age', 25);

饼干。移除(名称);

删除cookie。

name: cookie name.

Example

cookie.remove( 'age' );

用法示例

对于那些需要保存{foo: 'bar'}这样的对象的人，我分享了我编辑过的@KevinBurke的答案。我添加了JSON。stringify和JSON。解析，仅此而已。

cookie = {

    set: function (name, value, days) {
        if (days) {
            var date = new Date();
            date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
            var expires = "; expires=" + date.toGMTString();
        }
        else
            var expires = "";
        document.cookie = name + "=" + JSON.stringify(value) + expires + "; path=/";
    },

    get : function(name){
        var nameEQ = name + "=",
            ca = document.cookie.split(';');

        for(var i=0;i < ca.length;i++) {
          var c = ca[i];
          while (c.charAt(0)==' ') c = c.substring(1,c.length);
            if (c.indexOf(nameEQ) == 0) 
              return  JSON.parse(c.substring(nameEQ.length,c.length));
        }

        return null;
    }

}

现在你可以这样做:

cookie.set('cookie_key', {foo: 'bar'}, 30);

cookie.get('cookie_key'); // {foo: 'bar'}

cookie.set('cookie_key', 'baz', 30);

cookie.get('cookie_key'); // 'baz'

这是一个代码获取，设置和删除Cookie在JavaScript。

function getCookie(name) { name = name + "="; var cookies = document.cookie.split(';'); for(var i = 0; i <cookies.length; i++) { var cookie = cookies[i]; while (cookie.charAt(0)==' ') { cookie = cookie.substring(1); } if (cookie.indexOf(name) == 0) { return cookie.substring(name.length,cookie.length); } } return ""; } function setCookie(name, value, expirydays) { var d = new Date(); d.setTime(d.getTime() + (expirydays*24*60*60*1000)); var expires = "expires="+ d.toUTCString(); document.cookie = name + "=" + value + "; " + expires; } function deleteCookie(name){ setCookie(name,"",-1); }

我写了简单的cookie utils，它有三个功能创建cookie，读取cookie和删除cookie。

var CookieUtils = {
    createCookie: function (name, value, expireTime) {
        expireTime = !!expireTime ? expireTime : (15 * 60 * 1000); // Default 15 min
        var date = new Date();
        date.setTime(date.getTime() + expireTime);
        var expires = "; expires=" + date.toGMTString();
        document.cookie = name + "=" + value + expires + "; path=/";
    },
    getCookie: function (name) {
        var value = "; " + document.cookie;
        var parts = value.split("; " + name + "=");
        if (parts.length == 2) {
            return parts.pop().split(";").shift();
        }
    },
    deleteCookie: function(name) {
        document.cookie = name +'=; Path=/; Expires=Thu, 01 Jan 1970 00:00:01 GMT;';
    }
};

我使用以下函数，这些函数是我从各种来源中找到的最好的函数，并剔除了一些错误或差异。

函数setCookie没有高级选项，只有简单的东西，但代码很容易理解，这总是一个优点:

function setCookie(name, value, daysToLive = 3650) { // 10 years default
  let cookie = name + "=" + encodeURIComponent(value);
  if (typeof daysToLive === "number") {
    cookie += "; max-age=" + (daysToLive * 24 * 60 * 60);
    document.cookie = cookie + ";path=/";
  }
}
function getCookie(name) {
  let cookieArr = document.cookie.split(";");
  for (let i = 0; i < cookieArr.length; i++) {
    let cookiePair = cookieArr[i].split("=");
    if (name == cookiePair[0].trim()) {
      return decodeURIComponent(cookiePair[1].trim());
    }
  }
  return undefined;
}
function deleteCookie(name) {
  setCookie(name, '', -1);
}
