效果:

下面是核心代碼 複製代碼 代碼如下:GAME = {
//隨機產生字母
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");
//隨機產生字母
var index = Math.floor(Math.random() * 26);
return arrLetter[index];
},
//隨機字母顏色
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];
},
//建立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;
//擷取按鍵的值
document.onkeydown = function() {
//按鍵的字母是不是 等於 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";
}
}
}
//到達底線就消失,之後再建立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';
}

}

效果示範
Snmon轉正題目 - -||| ,題目需求還要複雜100倍。。。

暫時只實現了隨機產生字母,已監聽鍵盤,還未計算得分。

solid" id="map">得分:
