cookie写入存储与读取键值对函数
function setCookie(name, value, expires, path, domain, secure){ var cookieName = encodeURIComponent(name) + '=' + encodeURIComponent(value); if(expires instanceof Date){ cookieName += '; expires=' + expires; } if(path){ cookieName += '; path=' + path; } if(domain){ cookieName += '; domain=' + domain; } if(secure){ cookieName += '; secure'; } document.cookie=cookieName; } function getCookie(name){ var cookieName = encodeURIComponent(name) + '='; var cookieStart = document.cookie.indexOf(cookieName); var cookieValue = null; if(cookieStart>-1){ var cookieEnd = document.cookie.indexOf(';', cookieStart); if(cookieEnd == -1){ cookieEnd = document.cookie.length; } cookieValue = document.cookie.substring(cookieStart + cookieName.length , cookieEnd); } return cookieValue; } console.log(getCookie('email')); function setCookieDate(day){ var date = null; if(typeof day == 'number' && day>0){ date = new Date(); date.setDate(date.getDate()+day); }else{ throw new Error('您传递的天数不合法!必须是数字且大于0'); } return date.toGMTString(); }
setCookie('user', '乐乐乐', setCookieDate(7)); setCookie('url', 'yfdsae.com', setCookieDate(7)); setCookie('email', 'yc69@13.com', setCookieDate(7));
PS: name=value; [expires=time; path=path; domain='域名'; secure='安全加密链接';]
