Question

我创建了一个导航窗口 - Titanium.UI.iOS.NavigationWindow

我添加了三个窗口

我打开了所有三个窗口

现在我如何让window3先关闭window1和window 2

var ani =false;
var winRoot = Titanium.UI.createWindow({
  backgroundColor: 'red',
  title: 'Red Window'
});


var win = Titanium.UI.iOS.createNavigationWindow({
  window: winRoot
});

var button = Titanium.UI.createButton({
    title: 'Open Blue Window'
});
button.addEventListener('click', function(){
    win.openWindow(win1, {animated:ani});
});

winRoot.add(button);





var win1 = Titanium.UI.createWindow({
  backgroundColor: 'blue',
  title: 'Blue Window'
});

var button1 = Titanium.UI.createButton({
    title: 'Open Green Window'
});
button1.addEventListener('click', function(){
    win.openWindow(win2, {animated:ani});
});

win1.add(button1);






var win2 = Titanium.UI.createWindow({
  backgroundColor: 'green',
  title: 'green Window'
});

var button2 = Titanium.UI.createButton({
    title: 'Open Yellow Window'
});
button2.addEventListener('click', function(){
    win.openWindow(win3, {animated:ani});
});

win2.add(button2);





var win3 = Titanium.UI.createWindow({
  backgroundColor: 'yellow',
  title: 'yellow Window'
});



var button3 = Titanium.UI.createButton({
    title: 'Open Blue Window'
});
button3.addEventListener('click', function(){
    win.openWindow(win1, {animated:ani});
});

win3.add(button3);


win.open();

在button3中，如果不关闭黄色和绿色窗口，我将无法返回蓝色窗口

您无法在NavigationWindow中打开两次相同的窗口。如果你想把它带到前面你必须关闭它而不是再次打开：

以下是您修改的代码。我创建了一个事件监听器，它根据按钮自定义属性target关闭并打开给定窗口：

var windows = {};

function openWindow() {
    win.closeWindow( windows[this.target] );    
    win.openWindow( windows[this.target] );
}

windows.red = Titanium.UI.createWindow({
  backgroundColor: 'red',
  title: 'Red Window'
});

var win = Titanium.UI.iOS.createNavigationWindow({
    window: windows.red
});

var button = Titanium.UI.createButton({
    title: 'Open Blue Window',
    target: 'blue'
});
button.addEventListener('click', openWindow);
windows.red.add(button);


windows.blue = Titanium.UI.createWindow({
  backgroundColor: 'blue',
  title: 'Blue Window'
});

var button1 = Titanium.UI.createButton({
    title: 'Open Green Window',
    target: 'green'
});
button1.addEventListener('click', openWindow);
windows.blue.add(button1);


windows.green = Titanium.UI.createWindow({
  backgroundColor: 'green',
  title: 'green Window'
});

var button2 = Titanium.UI.createButton({
    title: 'Open Yellow Window',
    target: 'yellow'
});
button2.addEventListener('click', openWindow);
windows.green.add(button2);


windows.yellow = Titanium.UI.createWindow({
  backgroundColor: 'yellow',
  title: 'yellow Window'
});

var button3 = Titanium.UI.createButton({
    title: 'Open Blue Window',
    target: 'blue',
});
button3.addEventListener('click', openWindow);
windows.yellow.add(button3);


win.open();

另一种方法是创建具有相同参数的新窗口：

var params = {
    red: {
        window: {
            backgroundColor: 'red',
            title: 'Red Window',
        },
        button: {
            title: 'Open Blue Window',
            target: 'blue'
        }
    },
    blue: {
        window: {
            backgroundColor: 'blue',
            title: 'Blue Window',
        },
        button: {
            title: 'Open Green Window',
            target: 'green'
        }
    },
    green: {
        window: {
            backgroundColor: 'green',
            title: 'Green Window',
        },
        button: {
            title: 'Open Yellow Window',
            target: 'yellow'
        }
    },
    yellow: {
        window: {
            backgroundColor: 'yellow',
            title: 'Yellow Window',
        },
        button: {
            title: 'Open Red Window',
            target: 'red'
        }
    }
};

function createWindow(color) {
    var win = Titanium.UI.createWindow(params[color].window);
    var button = Titanium.UI.createButton(params[color].button);
    win.add(button);
    button.addEventListener('click', function() {
        navwin.openWindow( createWindow( this.target ) );
    });
    return win;
}

var navwin = Titanium.UI.iOS.createNavigationWindow({
    window: createWindow('red')
});

navwin.open();

尝试这两个示例并检查哪种行为更适合您。
