Question

我是PhoneGap开发的新手。我的PhoneGap应用程序有一个登录页面，我需要实现一个＆＃34;记住我＆＃34;进入此登录页面的选项。我不知道任何人都可以帮助我的这个功能。我想要一些关于此功能的示例代码。

请参阅以下我试过的代码，

function checkPreAuth() {
    /* console.log("checkPreAuth");*/
    if(window.localStorage.getItem("remember") == true)
    {
        if(window.localStorage.getItem("username") != undefined && window.localStorage.getItem("password") != undefined) {

            var form = $("#loginForm");
            $("#Username", form).val(window.localStorage.getItem("username"));
            $("#Password", form).val(window.localStorage.getItem("password"));
            $("#remember_me", form).attr('checked', true).checkboxradio("refresh");
    handleLogin();
        }
    }
}

$(document).on('pageinit', '#loginPage', function(){
               //getTimezoneName();
                $('#submitButton').click(function(e){
                                         e.preventDefault();
                                         var u = $("#Username").val();
                                         var p = $("#Password").val();
handleLogin();
});
});

function handleLogin()
{
    var form = $("#loginForm");
    $("#submitButton",form).attr("disabled","disabled");
    var u = $("#Username", form).val();
    var p = $("#Password", form).val();
    if(u != '' && p!= '')
    {        
        $.ajax({
               url: 'http://samplewebsite.com/API/login_api',
               type: 'post',
               dataType: 'json',
               data: $('form#loginForm').serialize(),
               crossDomain: 'true',
               success: function(data)
               {
               if(data)
               {
               //window.localStorage.setItem("key", "value");
               // var keyname = window.localStorage.key(i);
               if($("#remember_me").is(':checked'))
               {
               window.localStorage.setItem("remember", $("#remember_me").is(':checked'));
               }
               window.localStorage.setItem("userId", data.id);
               window.localStorage.setItem("username", u);
               window.localStorage.setItem("password", p);

               $.mobile.changePage("Inbox.html");
               }
               else
               {
               navigator.notification.alert("Your login failed", function() {});               
               }              

               },error: function (xhr, ajaxOptions, thrownError) {               
               navigator.notification.alert("Your login failed",null);
               }

               });
    }
    else
    {
        navigator.notification.alert("You must enter a username and password", function() {},"");       
    }    
}
