我无法从一个窗口导航到另一个窗口

Question

我想从 Login.js 导航到 home.js，以便任何帮助我的人。

//app.js

var win = Titanium.UI.currentWindow;

var tabbar = Ti.UI.createTabGroup({
    title:"Login"
    });

var mainwin = Ti.UI.createWindow({
    url:"Login/login.js"
    });
var signupwin = Ti.UI.createWindow({
    url:"Login/Home.js"
    });

var tabLogin = Ti.UI.createTab({
    title:"Login",
    window:mainwin
    });

var tabsignup = Ti.UI.createTab({
    title:"SignUp",
    window:signupwin
    });

var nav = Titanium.UI.iPhone.createNavigationGroup({
    window:mainwin
    });


tabbar.addTab(tabLogin);
tabbar.addTab(tabsignup);    
tabbar.open({
    transition:Titanium.UI.iPhone.AnimationStyle.CURL_UP
  });
//-------------------------------------------------------
//Login.js

//Ti.include('Homescreen/HomeScreen.js');

var win = Ti.UI.currentWindow;
win.title="Login";

var win1 = Titanium.UI.createWindow({ 
        title:'first window',
        backgroundColor:'#fff'
    });

var lbluser = Ti.UI.createLabel({
        text:"UserName",
        width: 60,
        height: 32,
        left: 10,
        font:{fontcolor:"blue",fontsize:12},
        top: 10
    });

win.add(lbluser);

var username = Titanium.UI.createTextField({

loginBtn.addEventListener('click',function(e)
{
    if (username.value == 'Bimal' && password.value == 'Pass')
    { 
      alert("ok");
       var home = Ti.UI.createWindow({

您应该能够使用正确的索引调用 setActiveTab。

例如，如果您将以下按钮代码放入 login.js 中，则按下按钮时应将焦点设置到主页选项卡。

var win = Ti.UI.currentWindow;
var tabGroup = win.tabGroup;
var b1 = Ti.UI.createButton({
    title : 'Press Me',
    left : 10, top : 100, right : 10, height : 40
});

b1.addEventListener('click', function(e) {
   tabGroup.setActiveTab(1);
});

win.add(b1);
