Javascript typing game implementation code _ javascript skills

Javascript typing game implementation code, very good results, the function is not very complete, like a friend can refer. Effect:

Below is the core code

The Code is as follows:

GAME = {
// Randomly generate letters
RandLetter: function (){
Var arrLetter = new Array ("A", "B", "C", "D", "E", "F", "G", "H ", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R ", "S", "T", "U", "V", "W ",
"X ",
"Y", "Z ");
// Randomly generate letters
Var index = Math. floor (Math. random () * 26 );
Return arrLetter [index];
},
// Random letter color
RandLetterColor: function (){
Var arrLetterColor = new Array ("Red", "Green", "#555", "Blue", "Black ");
Var index = Math. floor (Math. random () * 4 );
Return arrLetterColor [index];
},
// Random letter size
RandLetterSize: function (){
Var arrLetterSize = new Array ("12px", "16px", "20px", "24px", "28px", "32px", "36px", "40px ");
Var index = Math. floor (Math. random () * 7 );
Return arrLetterSize [index];
},
// Create a DIV
PCreate: function (width, height, left, top, value ){
This. width = width;
This. height = height;
This. p = document. createElement ("p ");
This. p. style. width = width;
This. p. style. height = height;
This. p. style. left = left;
This. p. style. top = top;
This. p. innerText = value;
This. p. style. color = this. randLetterColor ();
This. p. style. fontSize = this. randLetterSize ();
This. p. style. lineHeight = this. p. style. height;
This. p. style. textAlign = "center ";
This. p. style. fontWeight = "bold ";
// This. p. style. border = "solid red 1px ";
This. p. style. position = "relative ";
Document. getElementById ("map"). appendChild (this. p );
Return this. p;
},
// DIV whereabouts
PDown: function (){
Var pTop = parseInt (this. p. style. top. slice (0,-2); // Top of the letter box
Var mapHeight = parseInt (document. getElementById ("map"). style. height. slice (0,-2 ));
// Disappear
If (pTop <mapHeight-parseInt (this. height) + 20 ){
This. p. style. top = pTop + 30;
// Obtain the key value
Document. onkeydown = function (){
// Whether the key letter is equal to the value of p
If (String. fromCharCode (event. keyCode) = GAME. p. innerText ){
Document. getElementById ("TextRecord"). value = "correct ";
GAME. p. style. display = "none ";
ClearInterval (GAME. timeCreateID );
GAME. pCreate (100,100, Math. floor (Math. random () * 300),-30, GAME. randLetter ());
}
Else {
Document. getElementById ("TextRecord"). value = "error ";
}
}
}
// Disappear when the bottom line is reached, and then create a DIV
Else {
This. p. style. display = "none ";
GAME. pCreate (100,100, Math. floor (Math. random () * 300),-30, this. randLetter ());
}
},
TimeCreateID: null,
TimeDownID: null,
START: function (){
This. pCreate (100,100,200,-40, this. randLetter ());
This. timeDownID = setInterval ("GAME. pDown ();", 1000 );
Document. getElementById ('buttonstart'). disabled = 'Disabled ';
Document. getElementById ('buttonstop'). disabled = '';
},
STOP: function (){
If (this. timeDownID! = Null ){
ClearInterval (this. timeDownID );
This. p. style. display = "none ";
}
Document. getElementById ('buttonstart'). disabled = '';
Document. getElementById ('buttonstop'). disabled = 'Disabled ';
}

}
