Question

Is it possible to disable a certain keyboard key (like asterisk or string) by using jquery?

Answer 1

You can’t disable a key stroke as such but you could capture it with jQuery and overwrite its action (return false). The example below captures the enter key. Just change 13 to any key code you need to disable.

$("input").keypress(function (evt) {

  var keycode = evt.charCode || evt.keyCode;
  if (keycode  == 13) { //Enter key's keycode
    return false;
  }
});
