Chrome can’t find jquery.min.map

Recently, one of our users reported getting this message when running in Chrome:

mailmaperror

It’s not one you need to worry about. It only happens when you are running with the Chrome Debugger open. It’s complaining that it does not have the extra files it needs to display the jQuery source code properly. Since it is very unlikely that you will have any need to look at that code, it doesn’t matter.

If it really bugs you, you can go into the Debugger Preferences and turn off the warning. The setting to turn off is “Enable Source Maps”.

There is more info here.

A handy little Chrome trick: FullScreen

Google recently added a little trick to Chrome, allowing apps to become full screen. It works on both the Desktop and Android devices. You’ll need to be running Chrome Version 32 or newer.

To use it, add a button to your app with the following code:

Function btnChrome_onclick()
  document.documentElement.webkitRequestFullScreen()
End Function


After going to full screen, a message is displayed telling how to go back: swipe down on an Android device or hit escape on the desktop. As of Chrome 32, this is no longer needed.

Here’s how it looks on an Android device.

If you want to execute some code after the resize (perhaps to move controls to take advantage of the larger screen, do the following:

Function window_onresize()
  Print "resize"
  '… do any housekeeping
End Function

If you want hide the button if you are not using Chrome, add this code to your global code:

  If Not window.chrome Then btnChrome.hide()

A few gotchas:

  • This won’t work with the Android Browser or iOS.
  • This won’t work with PhoneGap, as long as it still uses the Android Browser.
  • It seems to have to be done from a button: just putting it in Global Code does not work.

Let us know if you find out anything more about this trick!

A couple of debugging tricks…

Examine variables in a running app

You can examine the value of global variables in a running app on any device, without needing to have a debugger hooked up.

Simply enter this into the URL bar:

javascript:alert(a)

This will display the value of a in a message box.

You can also use this to call functions:

javascript:alert(window.innerHeight)

You can enter any valid JavaScript code and it will execute in the current context.

Wow.

View JavaScript errors on Android devices

It’s not easy to see JavaScript errors on Android devices, especially older ones. To do this, you will need to have the Android SDK installed.

Start the simulator or connect your device in debug mode.

Open up a command window and type

adb logcat

You will see a stream of output with all the messages from the device or simulator. The error message will look something like this:


D/dalvikvm(  284): GC_FOR_MALLOC freed 34 objects / 2096 bytes in 212ms
E/browser (  284): Console: TypeError: defineProperty is not supported on DOM Ob
