我简单做了以下代码，可以直接保存为htm文件。
我在 IE 及 FireFox 下测试通过。
<html>
<script language="javascript">
var str1 = "";
var str2 = "";
var str3 = "";
var str4 = "";
var real_answer = "";
var C_TIMES = 10;
var guess_times;
function funcInit(){
while(real_answer==""){
str1 = funcR()+"";
str2 = funcR()+"";
str3 = funcR()+"";
str4 = funcR()+"";
real_answer = str1 + str2 + str3 + str4;
}
guess_times = C_TIMES;
document.getElementById("real_answer").innerHTML = guess_times + " times";
document.getElementById("res").innerHTML = "";
document.getElementById("btn_ok").style.display = "";
document.getElementById("btn_restart").style.display = "none";
document.getElementsByName("answer")[0].value="";
}
function funcR()
{
return Math.round((Math.random()*100))%10;
}
function isExist(strSrc,strDes){
var k=0;
for(i=0;i<strDes.length;i++)
{
for(j=0;j<strSrc.length;j++)
{
if(strDes.substr(i,1)==strSrc.substr(j,1))
{
k++;
}
}
}
if(k==0)
{
return false;
}
return true;
}
function funcChkNum(str)
{
var strTem = "0123456789";
var k=0;
for(i=0;i<str.length;i++)
{
for(j=0;j<strTem.length;j++)
{

{

}
}
if(k!=str.length)
{
return false;
}
return true;
}
function funcCheck(instr){
var tem1 = instr.substr(0,1);
var tem2 = instr.substr(1,1);
var tem3 = instr.substr(2,1);
var tem4 = instr.substr(3,1);
var A = 0;
var B = 0;
var res = "";

</script>
<body onload="funcInit();">

要用作网站的门还是用java吧
#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include <process.h>
void main(void)
{
int answer[4].guess=0,a,b,times=0,i,j;
for i=0;i<=3;i++)
{
randomize();
answer[i]=rand()%10;
for(j=0;j<i;j++)
{
while(answer[i]==answer[j])
{
answer[i]=rand()%10;
j=-1;
}
}
}
printf(\"please guess\\n\");
while(a!=4)
{
b=0;
times++;
do
{
printf(\"%d \",times);
scanf(\"%d\",&guess);
if(guess==0)
exit(0);
}
while(guess<0||guess>9999);
for(i=3;i>-1;i--)
{
for(j=0;j<4;j++)
{
if((int)(guess/pow10(i))=answer[j])
{
if(i+j==3) a=a+1;
else
b=b+1;
}
}
guess=guess-(int)(guess/pow10(i))*pow10(i);
}
printf(\" %dA%dB\\n\",a,b);
}
}
