Titanium，从另一个JS文件调用一个JS文件中的函数

Question

so i have been trying for many hours a day now for the past 3 days.i researched this to death but still cannot get it.

Goal:

-file1.js has a buttion that when pressed will call method Main_Menu in file2.js and will open a new window created by that method, or function.

failed attempts:

-i have tried Ti.include but always getting a, cant find file error, i have tried changing string to every possible path.

-var file = require(path) but can not use the method inside the file, for example file.Main_Meue, does not work

I have also tried many other things that do not come to mind but if anyone has any advice or you need more information just ask. PLEASE HELP, AND THANKYOU

Answer 1

second answer

Create the second window like so:

//file1.js
button.addEventListener('click', function()
{
  var secondWindow = Ti.UI.createWindow({
    url:'file2.js'
  });
  secondWindow.open();
});

file1.js creates a new window using file2.js via the url parameter. file2.js is now your new window after calling secondWindow.open()

First answer

Based off the title of this topic, you can use the fireEvent method. For example:

file1.js

Ti.App.addEventListener('customEventName', function()
{
  Ti.API.info('function fired from file2.js');
});

file2.js

Ti.App.fireEvent('customEventName');

Answer 2

file1.js

var toBeExported ={
a : function(){
    //your code goes here 
  }
};
exports.a = toBeExported.a

file2.js

 var b = require ('file1');
//you can use all the functions that is exported from file1 here.
//you have to create a lib folder or place the file1.js in the existing lib folder for the export/require to work.

Hope this will help.

Answer 3

this might be a problem of code structure. Basically you have three good way to doing this depending on which version you are using (actually on which version you started your project :

• before 2.x : the best way was call the tweetanium architecture : www.shanestillwell.com/index.php/2012/03/29/mvc-for-appcelerator-titanium-understanding-tweetanium/
• for 2.x : you can use the CommonJS structure : https://wiki.appcelerator.org/display/guides/CommonJS+Modules+in+Titanium
• for 3.x : you should take a look at the Alloy.Globals which is the almost the same than tweetanium

Hope it helps.
