Appcelerator Titanium: How to use the onLoad event of an Window?
提问by theJava
mainWin.pageLoad=false;
mainWin.addEventListener('load', function(e) {
if(mainWin.pageLoad) {
mainWin.open();
} else {
mainWin.close();
var LoginWindow = Titanium.UI.createWindow({
title : 'Login',
url:'Login.js'
});
LoginWindow.open();
}
});
This is my app.js file. If the pageLoad variable holds the boolean value true, then i need to navigate to mainWin {Which is the current Window}else i need to go to Login Page.
这是我的 app.js 文件。如果 pageLoad 变量保持布尔值 true，那么我需要导航到 mainWin{Which is the current Window}否则我需要转到登录页面。

var LoginWindow = Titanium.UI.createWindow ({
backgroundColor:'#1E563F',
url:'Login.js',
});
mainWin.addEventListener('open', checkPage);
mainWin.pageLoad = false;
function checkPage() {
if(mainWin.pageLoad) {
mainWin.open();
} else {
mainWin.close();
LoginWindow.open();
}
}
mainWin.open();
This should work....

Did you try to put your code like this ?
你试过把你的代码写成这样吗？
mainWin.pageLoad = false;
mainWin.addEventListener('load', function(e) {
if(mainWin.pageLoad) {
mainWin.open();
} else {
mainWin.close();
var LoginWindow = Titanium.UI.createWindow({
title : 'Login',
url:'Login.js'
});
LoginWindow.open();
}
});

The reason is probably that the the variable is updated to true before the event is dispatched. Did you try to print to console the mainWin.pageLoad value? Where do you update the variable to true?
原因可能是该变量在调度事件之前更新为 true。您是否尝试打印以控制台 mainWin.pageLoad 值？你在哪里更新变量为真？

try using the focusevent instead of the load event.
尝试使用focus事件而不是加载事件。
