All I want to do is measure screen height. “variable=window.screen.height” and “variable=screen.height” both work in the emulator, but not on my iPhone 4S with iOS 6.

Did this api work on previous versions of ios or iphone/ipad devices?

Did you try googling stackoverflow for known issues with such js code?

To be clear, I’m talking about an iOS native app.

I don’t know if it worked on previous versions. I do not have the resources to determine this.

From the googling I’ve done, it seems like window.screen.height is the way to do it in HTML5.

Perhaps there is bug in your code somewhere. The api works fine. You can verify this quickly

enter the following statement in mobile safari address bar

alert(screen.height)

Or you can try out this simple mobione UI that displays the display height and width

Perhaps I need to convert it to an integer?

At the moment, I am saying n=window.screen.height; then displaying it to the screen to see if it works ($(#m1-pagename-textwidgetname).text(n); this fails) then an if statement to go to a page based on if n is over/under 500: phoneui.gotopage(‘m1-pagename’)- also fails.

Given that it’s not displaying it to the screen or doing the gotopage, something’s wrong here.

This all works perfecty in the emulator. Fails on real hardware.

did you look at the example I provided? It works on iphone5/ios6. I tested it there and in mobile safari before posting it.

It’s 6am here – will let you know in a few hours 🙂

[support-michael]

I understand completely. It’s 5AM here atm.

Ok, that works as a native app.

Where am I going wrong here?

phoneui.documentReadyHandler = function() {

n=window.screen.height;

if (n < 500)
 {
  phoneui.gotoPage('m1-page1', 'NONE');}
if (n > 500)
 {
  phoneui.gotoPage('m1-page2', 'NONE');}
}

Note: page1 and page2 are included in the project during compliation.

Well, I’m embarased to say that I think it may have been an capitalization issue. “HomeScreen_custom.js” versus “Homescreen_custom.js”, as it seems to be working now.

Thanks for your help!
