javascript 打字游戲?qū)崿F(xiàn)代碼，非常不錯的效果，功能還不是很完善，喜歡的朋友可以參考下。

效果如圖所示:

下面是核心代碼

復(fù)制代碼代碼如下:

GAME = { 
//隨機(jī)產(chǎn)生字母 
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"); 
//隨機(jī)產(chǎn)生字母 
var index = Math.floor(Math.random() * 26); 
return arrLetter[index]; 
}, 
//隨機(jī)字母顏色 
randLetterColor: function() { 
var arrLetterColor = new Array("Red", "Green", "#555", "Blue", "Black"); 
var index = Math.floor(Math.random() * 4); 
return arrLetterColor[index]; 
}, 
//隨機(jī)字母大小 
randLetterSize: function() { 
var arrLetterSize = new Array("12px", "16px", "20px", "24px", "28px", "32px", "36px", "40px"); 
var index = Math.floor(Math.random() * 7); 
return arrLetterSize[index]; 
}, 
//創(chuàng)建DIV 
divCreate: function(width, height, left, top, value) { 
this.width = width; 
this.height = height; 
this.div = document.createElement("div"); 
this.div.style.width = width; 
this.div.style.height = height; 
this.div.style.left = left; 
this.div.style.top = top; 
this.div.innerText = value; 
this.div.style.color = this.randLetterColor(); 
this.div.style.fontSize = this.randLetterSize(); 
this.div.style.lineHeight = this.div.style.height; 
this.div.style.textAlign = "center"; 
this.div.style.fontWeight = "bold"; 
//this.div.style.border = "solid red 1px"; 
this.div.style.position = "relative"; 
document.getElementById("map").appendChild(this.div); 
return this.div; 
}, 
//DIV下落 
divDown: function() { 
var divTop = parseInt(this.div.style.top.slice(0, -2)); //字母方塊的Top 
var mapHeight = parseInt(document.getElementById("map").style.height.slice(0, -2)); 
//就消失 
if (divTop < mapHeight - parseInt(this.height) + 20) { 
this.div.style.top = divTop + 30; 
//獲取按鍵的值 
document.onkeydown = function() { 
//按鍵的字母是不是 等于 div的值 
if (String.fromCharCode(event.keyCode) == GAME.div.innerText) { 
document.getElementById("TextRecord").value = "正確"; 
GAME.div.style.display = "none"; 
clearInterval(GAME.timeCreateID); 
GAME.divCreate(100, 100, Math.floor(Math.random() * 300), -30, GAME.randLetter()); 
} 
else { 
document.getElementById("TextRecord").value = "錯誤"; 
} 
} 
} 
//到達(dá)底線就消失，之后再創(chuàng)建DIV 
else { 
this.div.style.display = "none"; 
GAME.divCreate(100, 100, Math.floor(Math.random() * 300), -30, this.randLetter()); 
} 
}, 
timeCreateID: null, 
timeDownID: null, 
START: function() { 
this.divCreate(100, 100, 200, -40, this.randLetter()); 
this.timeDownID = setInterval("GAME.divDown();", 1000); 
document.getElementById('ButtonStart').disabled = 'disabled'; 
document.getElementById('ButtonStop').disabled = ''; 
}, 
STOP: function() { 
if (this.timeDownID != null) { 
clearInterval(this.timeDownID); 
this.div.style.display = "none"; 
} 
document.getElementById('ButtonStart').disabled = ''; 
document.getElementById('ButtonStop').disabled = 'disabled'; 
}
