A universal x, y-axis positioning input method used for electronic devices having number keys, direction keys and a display screen integrates the characters and/or function keys into several character options to define a menu of columns in at least two rows displayed on the screen, and the menu can be divided into several pages if it is too large; a horizontal numerical row is disposed at the upper part of the menu for indicating the x-coordinates of the character options for selecting and controlling the x-coordinate of the character option by using the numerical keys; the values of y-coordinate, at first determining an initial value corresponding to the horizontal character option row, and then being displayed on the screen by a method other than those displaying the character option rows, finally, using direction keys to select and control the y-coordinate of the character option, and a row of character options can be selected each time; the way of selecting the x-coordinate is interchangeable with that for y-coordinate. Selecting the values of the x, y-axis for the desired character option from the menu completes the input. The invention overcomes the difficulties of locating the key mapping to the desired characters and having too many keystrokes, and also provides a simple, convenient and quick input method to be used universally for any character code sets and having the function keys effect.
