Tutorial: Multiple Keyboards for Accented Characters

Entering accented or other “unusual” characters in a web-form is a recurring problem, which is usually solved by placing a virtual keyboard on the page. I find these annoying as they take up real estate on the page and are not used most of the time. Moreover, I needed more than 1 keyboard (e.g. for entering last name and first name). I came up with a form with the following characteristics:

  • At most one visible keyboard
  • Keyboard disappears when any textbox is clicked
  • As long as keyboard is visible, clicking on it will enter characters into the calling field
