cookie记录

登录页面引用：

<script src="/jquery.cookie.js"></script>

登录页面jq:

var telphone = $('[name = "telphone"]').val();

var pwd = $('[name = "pwd"]').val();

//登录接口
$.post("/sign",{   
    login: telphone,
    password: pwd  
},function(data){
    if(data.status == 200){       
           //登录成功后跳转到首页
            if(parame == 'index'){//从首页点击登录跳转到登录页面的索引
                //设置cookie
                $.cookie('login',telphone,{ expires: 365, path: '/index.html' });
                $.cookie('token',data.data.access_token,{ expires: 365, path: '/index.html' });
                $.cookie('username',data.data.username,{ expires: 365, path: '/index.html' }); 
                $.cookie('pwd',encrypt(pwd),{ expires: 365, path: '/index.html' }); //密码
                window.location.href = '/index.html?login='+telphone+'&access_token='+data.data.access_token+'&username='+data.data.username+'';
            }         

    }
    else{
        alert(data.error);
    }
})

首页页面同样引用：

<script src="/request.js"></script>
<script src="/jquery.cookie.js"></script>

首页jq:

var login = request('login');

var token = request('access_token');

var username = request('username');

var pwd;//加密密码

//判断cookie中是否有登录的记录
if($.cookie('login') == undefined || $.cookie('login') == ''){

}else{
    login = $.cookie('login');
}
if($.cookie('token') == undefined || $.cookie('token') == ''){

}else{
    token = $.cookie('token');
}
if($.cookie('username') == undefined || $.cookie('username') == ''){

}else{
    username = $.cookie('username');
}
if($.cookie('pwd') == undefined || $.cookie('pwd') == ''){

}else{
    pwd = $.cookie('pwd');
}

//首页点击退出登录
$('.denglu').click(function(){
                  $.cookie('login','',{ path: '/index.html' });
                  $.cookie('token','',{ path: '/index.html' });
                  $.cookie('username','',{ path: '/index.html' });
                  $.cookie('pwd','',{ path: '/index.html' });
                  window.location.href = '/index.html';

         /*清除所有cookie:

                  $.cookie('login','',{ path: '/' });
                  $.cookie('token','',{ path: '/' });
                  $.cookie('username','',{ path: '/' });
                  $.cookie('pwd','',{ path: '/' });*/

});
