javascript创建cookie,javascript读取cookie,js创建cookie,js读取cookie本文内容分为两个部分进行学习，分别介绍了javascript创建cookie、javascript读取cookie的具体实现方法，供大家学习，具体内容如下 一、创建Cookie document.cookie = 'key=value'; 有特殊字符 使用encodeURIComponent() 进行编码 document.cookie = 'user='+encodeURIComponent('郭钱;');
读取时 使用decodeURIComponent() 例如： document.cookie = 'name=guoqian';document.cookie = 'age=24';document.cookie = 'address=hunan';document.cookie = 'user='+encodeURIComponent('郭钱;'); 自定义一个创建cookie方法 function SetCookie(name, value, expires, path, domain, secure) { var today = new Date(); today.setTime(today.getTime()); if(expires) { expires *= 86400000; } var expires_date = new Date(today.getTime() + (expires)); document.cookie = name + "=" + escape(value) + (expires ? ";expires=" + expires_date.toGMTString() : "") + (path ? ";path=" + path : "") + (domain ? ";domain=" + domain : "") + (secure ? ";secure" : "");}二、获取cookie 使用字符串方式 function getCookieByString(cookieName){ var start = document.cookie.indexOf(cookieName+'='); if (start == -1) return false; start = start+cookieName.length+1; var end = document.cookie.indexOf(';', start); if (end == -1) end=document.cookie.length; return document.cookie.substring(start, end);}使用数组方式 function getCookieByArray(name){ var cookies = document.cookie.split(';'); var c; for(var i=0; i<cookies.length ; i++){ c = cookies[i].split('='); if (c[0].replace(' ', '') == name) { return c[1]; } }}var r = decodeURIComponent(getCookieByArray('user'));alert(r);以上就是本文的全部内容，希望对大家的学习有所帮助。
