JavaScript typing game code_javascript skills

Function module: Program design:
1. You can select the game time and display the countdown 1. Define global variables
2. You can select the number of English letters to appear 2. Control the game time function
3. Statistical scores 3. Animation effect
4. Menu option 4. Set the time when the letter picture appears
5. Judgment function
6. Game menu
7. Game time option
8. Display game time
　　　　　　　9. Game difficulty options
　　　　　10. Game score
　
First, the renderings: (PS: The art is flawed)

Main code design:

Copy code The code is as follows:

 
//-------全局变量------- 
var data={ 
"10":[""],"11":[""],"12":[""],"13":[""], 
"14":[""],"15":[""],"16":[""],"17":[""], 
"18":[""],"19":[""],"20":[""],"21":[""], 
"22":[""],"23":[""],"24":[""],"25":[""], 
"26":[""],"27":[""],"28":[""],"29":[""], 
"30":[""],"31":[""],"32":[""],"33":[""], 
"34":[""],"35":[""]
};
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 Divs;//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--) {
window.setTimeout('Show(' + gametimes + ')',(gametime-gametimes+2) * 1000);
}
}
function Show(gametimes){
if(gametimes==0){
clearInterval(time1);//停止游戏
alert("游戏结束!你的得分为:"+count);
$("#main").empty();//清除main中的div
$(".gameapply").empty();
$("#select1").empty();
$("#select2").empty();
count=0;//得分清空为0
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.length=0;
for(var i=0;iImage=parseInt(Math.random() * 26)+10;//随机出现字母图片
datas.push(Image);//图片以数组中偶数存储,从零开始
Divs=parseInt(Math.random() * 8)+1;//随机出现层的class样式即层的不同位置
datas.push(Divs);//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 $divs=$("

"+data[Image]+"

");
$("#main").append($divs);
//-----JQ animation function----
$(".divPop" Divs). animate(
{"top":$(window).height() - $(".divPop" Divs).height() - $(".divPop" Divs).position().top},time, function(){$("#main").empty()})
}
}
}
//--------3. Set the letter picture to appear Time ------
function sets(){
time1 = setInterval(fun,time2);
}
//---------4. Bind keyboard ---------
//---------Compatible with FF browser---------
document.onkeydown = function keydown(e){
e = e||window.event;
var key = e.charCode||e.keyCode
select(key)
}
//--------- 5. Judgment function---------
function select(key){
if(key==13){
switch(tab){
case 0:Gametime() ;Gametimeselect();time3=setInterval(countdown,1000);sets();$("#select").hide(2000);break;//Start the game
case 1:Gametime();Gametimeselect() ;time3=setInterval(countdown,1000);sets();$("#select").hide(2000);break;//Start the game
case 2:alert("Game options can be set on the left" );break;
case 3:window.opener=null;window.open('','_self');window.close();break;//Exit the game
case 4:window.opener= null;window.open('','_self');window.close();break;//Exit the game
}
}
for(var j=0;jif(key== datas[j] 55){
$(".divPop" datas[j 1]).hide();//The key values ​​​​are equal, hide the layer
delete datas[j]; //In order to avoid having Duplicate letters, so every time a (key==datas[j] 55) is traversed in the array, this value must be deleted
count =10;
Score();
break;
}
}
}
//---------6. Game menu-------
function Focus(){
//----- ----Initialize the game interface--------
var $selects=$("

< ;td>

");
$(".gameapply").append($selects);
for( var i=30;i<=300;i=i 30){
$("#select1").append('' i '')
}
for(var j=1;j<=9;j ){
$("#select2").append('' j '')
}
//---------Get the focus of the first input at the beginning--------
$(".inputs:first").trigger("focus").addClass ("input1");
tab=1;//Because Enter cannot be entered in the first focus, the keyboard input event needs to be called
var tabIndex=1;
//----- -----Get the number of tr rows and the number of inputs--------
$("#tables").find("tr").each(function(r) {
$ (this).find("input").attr("tabindex", r 1);//tabindex is the value of the focus position, the initial value is assigned to 1, and the traversal is 1-2-3-4
}) ;
//---------Response to input keyboard up and down operations
$("#tables .inputs").bind("keydown", function(e){
tabIndex = parseInt($(this).attr("tabindex"));//Get the value of the current tabindex focus
switch(e.which){
case 38://up
tabIndex-=1;
tab=tabIndex;
break;
case 40://down
tabIndex =1;
tab=tabIndex;
break;
default:
return ;
}
//--------Determine the value of tabIndex focus
if (tabIndex > 0 && tabIndex < 4) {
$(".inputs[tabindex= " tabIndex "]").focus().addClass("input1"); //The current input gets focus
for(var i=0;i<=4;i )
{
if( i==tabIndex){
break;
}
else{
$(this).removeClass("input1");
}
}
keydown();
return false;
}
return true;
});
}
//--------7. Game time options------ ---
function Gametimeselect(){
var option=document.getElementById("select1");
for(var i=0;iif( option[i].selected) {
gametime=option.options[i].text;
gametimess=gametime;
}
}
}
//---- -8. Display game time -------
function countdown(){
var timesshows=document.getElementById("timeshow");
if(timeshows){//If the web page speed is very fast If it is slow, the control may not be loaded when the timer is running
if(gametimess<0){
clearInterval(time3);//Stop the timer
}
else{
timeshows. value=gametimess;
gametimess--;
}
}
}
//--------9. Game difficulty options---------
function Gameselectamount(){
var option=document.getElementById("select2");
for(var i=0;iif(option[i ].selected) {
amounts=option.options[i].text;
}
}
}
//---------10. Game score- ----------
function Score(){
var sum=document.getElementById("sum");
sum.value=count;
if(count== 0){ //Initialize the text box score to 0
sum.value=count;
}
}

Summary: Since the time interval is relatively long, the code has not been optimized. There is one place that is not done very well, that is, the time interval between letters appearing is too long. If you are interested, you can try to fix it. The code is for reference only
