实现不同用户登录显示不同页面

$(function(){    var e = getCookie("seller_key");    // 判断是否有登录     if (!e) {         location.href = "login.html"     }    if (getQueryString('seller_key') != '') {        var key = getQueryString('seller_key');        var seller_name = getQueryString('seller_name');        addCookie('seller_key', key);        addCookie('seller_name', seller_name);    } else {        var key = getCookie('seller_key');        var seller_name = getCookie('seller_name');    }    if(key && seller_name){        $.ajax({            type:'post',            url:ApiUrl+"/index.php?act=seller_index",            data:{key:key},            dataType:'json',            success:function(result){                checkSellerLogin(result.login);                var html = ''                    + '<div class="member-info">'                        + '<div class="user-avatar"><img src="' + result.datas.store_info.store_avatar + '"/></div>'                        + '<div class="user-name"><span>'+result.datas.seller_info.seller_name+'</span></div>'                    + '</div>';                $(".member-top").html(html);                return false;            }        });    } else {        // 未登录显示        delCookie('seller_key');        delCookie('seller_name');        delCookie('store_name');        var html = ''            + '<div class="member-info">'                + '<a href="login.html" class="default-avatar" style="display:block;"></a>'                + '<a href="login.html" class="to-login">点击登录</a>'            + '</div>';        $(".member-top").html(html);        return false;    }})

封装的函数

function getQueryString(e) {    //正则去除特殊符号    var t = new RegExp("(^|&)" + e + "=([^&]*)(&|$)");    //location.search是从当前URL的?号开始的字符串     //如:http://www.runoob.com/try/try.php?filename=tryjsref_search 它的search就是?   filename=tryjsref_search    //substr(1)去掉?匹配后面的信息    var a = window.location.search.substr(1).match(t);    if (a != null) return a[2];    return ""}function addCookie(e, t, a) {    var n = e + "=" + escape(t) + "; path=/";    if (a > 0) {        var r = new Date;        r.setTime(r.getTime() + a * 3600 * 1e3);        n = n + ";expires=" + r.toGMTString()    }    document.cookie = n}function getCookie(e) {    var t = document.cookie;    var a = t.split("; ");    for (var n = 0; n < a.length; n++) {        var r = a[n].split("=");        if (r[0] == e) return unescape(r[1])    }    return null}function delCookie(e) {    var t = new Date;    t.setTime(t.getTime() - 1);    var a = getCookie(e);    if (a != null) document.cookie = e + "=" + a + "; path=/;expires=" + t.toGMTString()}
