我無法從一個窗口導航到其他

Question

我想從Login.js導航到home.js，以便幫助我解決此問題的任何人。

//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({ 
    color:'#336699', 
    top:10, 
    left:50, 
    width:250, 
    height:40, 
    hintText:'Username', 
    keyboardType:Titanium.UI.KEYBOARD_DEFAULT, 
    returnKeyType:Titanium.UI.RETURNKEY_DEFAULT, 
    borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED 
}); 
win.add(username); 

var lblpass = Ti.UI.createLabel({ 
     text:"Password", 
     width: 60, 
     height: 32, 
     left: 10, 
     top: 50, 
     font:{fontcolor:"white",fontsize:12} 
    }); 

win.add(lblpass); 
var password = Titanium.UI.createTextField({ 
    color:'#336699', 
    top:60, 
    left:50, 
    width:250, 
    height:40, 
    hintText:'Password', 
    passwordMask:true, 
    keyboardType:Titanium.UI.KEYBOARD_DEFAULT, 
    returnKeyType:Titanium.UI.RETURNKEY_DEFAULT, 
    borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED 
}); 
win.add(password); 

var loginBtn = Titanium.UI.createButton({ 
    title:'Login', 
    top:110, 
    width:90, 
    height:35, 
    borderRadius:1, 
    font:{fontFamily:'Arial',fontWeight:'bold',fontSize:14} 
}); 
win.add(loginBtn); 


/* 
Login Button Click Event 
*/ 



loginBtn.addEventListener('click',function(e) 
{ 
    if (username.value == 'Bimal' && password.value == 'Pass') 
    { 
     alert("ok"); 
     var home = Ti.UI.createWindow({ 
      title:"Home Screen", 
      url:'Home.js', 
      _parent:win, 
      nav:win.nav, 
      rootWindow:win.rootWindow 
     }); 
     win.open(home); 
    } 
    else 
    { 
     alert("Username/Password are required"); 
    } 
}); 


win.open(); 

//----------------------------------------------- 
//Home.js 

var win = Titanium.UI.currentWindow; 

win.title = "Home Screen"; 
var username = Titanium.UI.createTextField({ 
    color:'#336699', 
    top:10, 
    left:50, 
    width:300, 
    height:40, 
    hintText:'Username', 
    keyboardType:Titanium.UI.KEYBOARD_DEFAULT, 
    returnKeyType:Titanium.UI.RETURNKEY_DEFAULT, 
    borderStyle:Titanium.UI.INPUT_BORDERSTYLE_ROUNDED 
}); 
win.add(username);

你應該能夠只是調用setActiveTab使用正確的索引。

例如，如果您將下面的按鈕代碼放入login.js中，則應該在按下按鈕時將焦點設置爲主頁選項卡。

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);
