一、js cookie 使用时把此段代码引入页面
(function (factory) { if (typeof define === ‘function‘ && define.amd) { define(factory); } else if (typeof exports === ‘object‘) { module.exports = factory(); } else { var _OldCookies = window.Cookies; var api = window.Cookies = factory(window.jQuery); api.noConflict = function () { window.Cookies = _OldCookies; return api; }; } }(function () { function extend () { var i = 0; var result = {}; for (; i < arguments.length; i++) { var attributes = arguments[ i ]; for (var key in attributes) { result[key] = attributes[key]; } } return result; } function init (converter) { function api (key, value, attributes) { var result; // Write if (arguments.length > 1) { attributes = extend({ path: ‘/‘ }, api.defaults, attributes); if (typeof attributes.expires === ‘number‘) { var expires = new Date(); expires.setMilliseconds(expires.getMilliseconds() + attributes.expires * 864e+5); attributes.expires = expires; } try { result = JSON.stringify(value); if (/^[\{\[]/.test(result)) { value = result; } } catch (e) {} value = encodeURIComponent(String(value)); value = value.replace(/%(23|24|26|2B|3A|3C|3E|3D|2F|3F|40|5B|5D|5E|60|7B|7D|7C)/g, decodeURIComponent); key = encodeURIComponent(String(key)); key = key.replace(/%(23|24|26|2B|5E|60|7C)/g, decodeURIComponent); key = key.replace(/[\(\)]/g, escape); return (document.cookie = [ key, ‘=‘, value, attributes.expires && ‘; expires=‘ + attributes.expires.toUTCString(), // use expires attribute, max-age is not supported by IE attributes.path && ‘; path=‘ + attributes.path, attributes.domain && ‘; domain=‘ + attributes.domain, attributes.secure ? ‘; secure‘ : ‘‘ ].join(‘‘)); } // Read if (!key) { result = {}; } // To prevent the for loop in the first place assign an empty array // in case there are no cookies at all. Also prevents odd result when // calling "get()" var cookies = document.cookie ? document.cookie.split(‘; ‘) : []; var rdecode = /(%[0-9A-Z]{2})+/g; var i = 0; for (; i < cookies.length; i++) { var parts = cookies[i].split(‘=‘); var name = parts[0].replace(rdecode, decodeURIComponent); var cookie = parts.slice(1).join(‘=‘); if (cookie.charAt(0) === ‘"‘) { cookie = cookie.slice(1, -1); } try { cookie = converter && converter(cookie, name) || cookie.replace(rdecode, decodeURIComponent); if (this.json) { try { cookie = JSON.parse(cookie); } catch (e) {} } if (key === name) { result = cookie; break; } if (!key) { result[name] = cookie; } } catch (e) {} } return result; } api.get = api.set = api; api.getJSON = function () { return api.apply({ json: true }, [].slice.call(arguments)); }; api.defaults = {}; api.remove = function (key, attributes) { api(key, ‘‘, extend(attributes, { expires: -1 })); }; api.withConverter = init; return api; } return init(); }));
设置cookie
Cookies(name, value); || Cookies.set(name, value); //name:所存cookie的名称;value:名称对应的值
Cookies(name1, value1); || Cookies.set(name1, value1);
Cookies(name,value, { expires: 7 }); || Cookies.set(name,value, { expires: 7 }); // 设置cookie失效时间,单位:天
Cookies(name,value, { expires: 7,path:"/路径",domain: "域名"}); || Cookies.set(name,value, { expires: 7,path:"/路径",domain: "域名"});// 设置cookie,包括有效期 路径 域名等
读取cookie
Cookies(); || Cookies.get(); //读取所有cookie,输出的是对象==>{name:value, name1:value1}
Cookies(name); || Cookies.get(name); //读取对应名称的cookie==>value
删除cookie
Cookies(name:""); //将cookie清空
Cookie.remove(name:""); //删除cookie 对应的cookie名称也删除
