I taught myself JavaScript in the first half of the year, and then I made a small typing game to play

Function module: Program design:
1. You can select the game time and display the countdown 1 .Define global variables
2. You can choose the number of English letters to appear 2. Control the game time function
3. Statistical scores 3. Animation effect
4. Menu options 4. Set the time when the letter picture appears
Display game time
First the renderings: (PS: The art is a flaw)


Main code design:


The code is as follows:

//-------全局变量------- 
var data={ 
"10":["<img src=&#39;images/A.gif&#39;/>"],"11":["<img src=&#39;images/B.gif&#39;/>"],"12":["<img src=&#39;images/C.gif&#39;/>"],"13":["<img src=&#39;images/D.gif&#39;/>"], 
"14":["<img src=&#39;images/E.gif&#39;/>"],"15":["<img src=&#39;images/F.gif&#39;/>"],"16":["<img src=&#39;images/G.gif&#39;/>"],"17":["<img src=&#39;images/H.gif&#39;/>"], 
"18":["<img src=&#39;images/I.gif&#39;/>"],"19":["<img src=&#39;images/J.gif&#39;/>"],"20":["<img src=&#39;images/K.gif&#39;/>"],"21":["<img src=&#39;images/L.gif&#39;/>"], 
"22":["<img src=&#39;images/M.gif&#39;/>"],"23":["<img src=&#39;images/N.gif&#39;/>"],"24":["<img src=&#39;images/O.gif&#39;/>"],"25":["<img src=&#39;images/P.gif&#39;/>"], 
"26":["<img src=&#39;images/Q.gif&#39;/>"],"27":["<img src=&#39;images/R.gif&#39;/>"],"28":["<img src=&#39;images/S.gif&#39;/>"],"29":["<img src=&#39;images/T.gif&#39;/>"], 
"30":["<img src=&#39;images/U.gif&#39;/>"],"31":["<img src=&#39;images/V.gif&#39;/>"],"32":["<img src=&#39;images/W.gif&#39;/>"],"33":["<img src=&#39;images/X.gif&#39;/>"], 
"34":["<img src=&#39;images/Y.gif&#39;/>"],"35":["<img src=&#39;images/Z.gif&#39;/>"] 
}; 
var datas=new Array();//随机出现的 class样式以数组中偶数存储,图片以数组中奇数存储 
var now=new Date(); 
var Image; //随机出现图片 
var ps;//随机出现层 
var count=0;//积分系统 
var key;//键盘的值 
var amounts=1;//出现字母图片的个数 
var gametime=30;//控制游戏的时间 
var gametimes;//时间为0 
var gametimess=30;//显示时钟变量 
var time1;//setInterval变量 
var time2=5000;//设定setInterval的时间 
var time3; 
var tab;//用来记录,传递tabindex焦点位置的值 
//--------这样写为了兼容FF浏览器------- 
var plug = { 
addEvent:function(o,e,f){ 
if(o.addEventListener){ 
o.addEventListener(e,f,false); 
} 
else if(o.attachEvent){ 
o.attachEvent("on"+e,f); 
} 
} 
} 
plug.addEvent(window,"load",function(){Focus()});//兼容FF浏览器 
//------1.控制游戏时间函数-------- 
function Gametime(){ 
for(gametimes=gametime;gametimes>=0;gametimes--) {

} 
} 
function Show(gametimes){

Score();//让分数框显示为0 
Focus();//重新生成菜单选项 
} 
} 
//---------2.动画效果--------- 
function fun(){

datas.push(Image);//图片以数组中偶数存储,从零开始 
ps=parseInt(Math.random() * 8)+1;//随机出现层的class样式即层的不同位置 
datas.push(ps);//样式以数组中奇数存储 
var time=parseInt(Math.random() * 2000)+3000;//完成动画的时间 
if(time<5000){ 
var $ps=$("<p class=&#39;pPop"+ps+"&#39;>"+data[Image]+"</p>"); 
$("#main").append($ps); 
//-----JQ动画函数---- 
$(".pPop"+ps).animate( 
{"top":$(window).height() - $(".pPop"+ps).height() - $(".pPop"+ps).position().top},time,function(){$("#main").empty()})

} 
} 
for(var j=0;j<datas.length;j=j+2){//为了让data1里面样式和图片的值不重复(即奇数跟偶数的不可能重复,m的值或者k的值要相差一定的值) 
if(key==datas[j]+55){ 
$(".pPop"+datas[j+1]).hide();//key值相等,隐藏该层
