我在我的 iphone Titan App 中传递变量时遇到问题。下面是我的 AppTabGroup.js 文件。有一个名为“grantEntrance”的事件监听器。当它被触发时,我需要将变量 event.name 和 event.email 传递给所有新选项卡。出于某种原因,这对我不起作用。我最终得到未定义的错误。我想我的问题是如何设置全局变量?与 event.name 类似,因此它显示在应用程序的任何位置。
function AppTabGroup() {
//declare module dependencies
var AppWindow = require('ui/AppWindow');
var OverviewWindow = require('ui/OverviewWindow');
var LeadWindow = require('ui/LeadWindow');
var CaseWindow = require('ui/CaseWindow');
var ResourcesWindow = require('ui/ResourcesWindow');
//create module instance
var self = Ti.UI.createTabGroup();
//create app tabs
var win1 = new OverviewWindow(L('Login')),
win2 = new CaseWindow(L('Cases'));
win3 = new LeadWindow(L('Leads'));
win4 = new ResourcesWindow(L('Resources'));
var tab1 = Ti.UI.createTab({
title: L('Login'),
icon: '/images/KS_nav_ui.png',
window: win1
});
win1.containingTab = tab1;
var tab2 = Ti.UI.createTab({
title: L('Cases'),
icon: '/images/KS_nav_views.png',
window: win2
});
win2.containingTab = tab2;
var tab3 = Ti.UI.createTab({
title: L('Leads'),
icon: '/images/KS_nav_views.png',
window: win3
});
win3.containingTab = tab3;
var tab4 = Ti.UI.createTab({
title: L('Resources'),
icon: '/images/KS_nav_mashup.png',
window: win4
});
win4.containingTab = tab4;
//Load Initial Login tab
self.addTab(tab1);
//If Login is successful then the below even will fire and the other tabs will be loaded
Ti.App.addEventListener('grantEntrance', function(event)
{
win2.name = event.name;
win2.email = event.email;
self.addTab(tab2);
self.addTab(tab3);
self.addTab(tab4);
self.removeTab(tab1);
});
return self;
};
module.exports = AppTabGroup;
下面是我的 CaseWindow.js 选项卡
function AppWindow(title) {
var Main = Ti.UI.createWindow({
title:title,
backgroundColor:'white'
});
//Closed Case Button
var ccButton = Titanium.UI.createButtonBar({
labels:['Closed'],
backgroundColor:'#336699'
});
Main.setLeftNavButton(ccButton);
//New Case Button
var ncButton = Titanium.UI.createButtonBar({
labels:['New Case'],
backgroundColor:'#336699'
});
Main.setRightNavButton(ncButton);
ncButton.addEventListener('click', function() {
//containingTab attribute must be set by parent tab group on
//the window for this work
Main.containingTab.open(Ti.UI.createWindow({
title: L('newCaseWindow'),
backgroundColor: 'white'
}));
});
var msg = Titanium.UI.createLabel({
text:"Your Name is " + win.name,
//text:"You have successfully logged in. Upon logging in we sent back your email address and your name. You can pass all kinds of data simply by creating objects on your window.\n\nYour email is:\n" + email + "\n\nyour name is:\n" + name,
top:10,
left:10,
width:300,
height:'auto'
});
Main.add(msg);
return Main;
};
module.exports = AppWindow;
