cookie读取方法

/** *设值**/function setCookie(cookiename,value) {    var today = new Date();    var expires = new Date();    expires.setTime(today.getTime() + 1000 * 60 * 60 * 24 * 365);    if(value == "") {        expires.setTime(today.getTime()-1);    }    document.cookie = cookiename + "=" + escape(value) + "; expires=" + expires.toGMTString()+";path=/";}/** *取值**/function getCookie(cookiename) {    var search = cookiename + "=";     var tmp = "";     if (document.cookie.length > 0) {        offset = document.cookie.indexOf(search);        if (offset != -1) {            offset += search.length;            end = document.cookie.indexOf(";", offset);            if (end == -1) {                end = document.cookie.length;            }            return unescape(document.cookie.substring(offset, end));        } else {            return ("");        }    } else {        return ("");    }}

?调用：

function window.onload() { //获取cookievar ntrain_rember = document.getElementsByName("intflag")[0].checked?"1":"0"; if(ntrain_rember == "1"){document.getElementsByName("userid")[0].value = getCookie("ntrain_user");}}function CheckForm(){var ntrain_rember = document.getElementsByName("intflag")[0].checked?"1":"0"; if(ntrain_rember == "1"){//设置cookiesetCookie('ntrain_user', document.getElementsByName("userid")[0].value);}else{setCookie("ntrain_user","");}return true;}
