  • 0

I’d like to assign the value in device.platform to a variable so I can check it later in my program.
For example, if the app is running on a BlackBerry I might want to have a custom message appear.

I used the “element” example found elsewhere to make sure things were working properly (and it does). But I run into problems when I try assigning just the “device.platform” value to devicePlatform.

I’ve been fighting with this for an hour, I must be missing something fairly basic.
Can someone please show me what I’m doing wrong?

Thanks
Rob

    Try putting

    var devicePlatform = device.platform;
document.write("Platform: "+devicePlatform+"<br>");

    into the function onDeviceReady()

    This should resolve the issue.

    Additionally you will probably want to define a globally scoped variable, such as ‘platform’ and then assign the device.platform to that variable in the function onDeviceReady().

    Example:

    var platform = null;
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
  platform = device.platform;
  alert(platform);
}

    UPDATE:

    I think this is closer to what you are looking for
