How to Check whether window property exists

You must Login before you can answer or comment on any questions.

Hey ,

I have the following code

Titanium.UI.createWindow({ url:'somenewcode.js', title:'your new window', oldWin:Ti.currentWindow // this gets you a pointer });

I want to check whether the oldWin exists in the window created.

I used this

if(Ti.UI.currentWindow.oldWin) { Ti.UI.currentWindow.oldWin.close(); }

but shows error. How can I check whether the oldWin exists

Hi Rebin

Fix this error and try again, if you still have a problem - report back.

Change this

Titanium.UI.createWindow({
  url:'somenewcode.js', 
  title:'your new window', 
  oldWin:Ti.currentWindow // this gets you a pointer
});

To this

Titanium.UI.createWindow({
  url:'somenewcode.js', 
  title:'your new window', 
  oldWin:Ti.UI.currentWindow // this gets you a pointer
});

Specific line

oldWin:Ti.UI.currentWindow // this gets you a pointer

Hi Rebin,

What is Ti.UI.currentWindow here - Is there any window that you created before creating this window? Can you please provide the complete code?

As far as I understand, this won't work because you are creating new window using url property which creates a new execution context where your previous variables/objects are not accessible.
