The real answer has to include keyCode   var e   jQuery Event  keydown    e which   50       Some key code value e keyCode   50    input   trigger e     Even though jQuery s website says that which and keyCode are normalized they are very badly mistaken  It s always safest to do the standard cross-browser checks for e which and e keyCode and in this case just define both

In case you need to take into account the current cursor and text selection     This wasn t working for me for an AngularJS app on Chrome  As Nadia points out in the original comments  the character is never visible in the input field  at least  that was my experience   In addition  the previous solutions don t take into account the current text selection in the input field  I had to use a wonderful library jquery-selection   I have a custom on-screen numeric keypad that fills in multiple input fields  I had to      On focus  save the lastFocus element On blur  save the current text selection  start and stop   var pos   element selection  getPos   lastFocus pos     start  pos start  end  pos end   When a button on the my keypad is pressed   lastFocus element selection   setPos   lastFocus pos  lastFocus element selection   replace    text  myKeyPadChar  caret   end
