Drop a letter from the top, enter a letter on the keyboard, and pass it correctly. The next letter is incorrect.

I know several key things when I write this game.

1. onkeydown event, when the mouse is pressed

2. For the onclick event, click

3. var a = (Math. random () * 500 );

Math. random () randomly generates 0-1 decimal places

4. String. fromCharCode (65 + (a * 100) % 26)

Convert a number to a char letter

5. event. keyCode

The value corresponding to the key pressed by the keyboard.

String. fromCharCode (event. keyCode)

6. setTimeout ("setHeight ()", 20 );

The number of millimeters per call .. Method

As long as you know about these games, the js games are basically the same.

---------------------- The following is my source code, which contains jquery, but the selector is used, so you don't need to thank document. getElementById (), others are useless -------------
