在同一页面上生成随机数字符串答案

【问题标题】：Generating random number strings on the same page在同一页面上生成随机数字符串
【发布时间】：2014-03-28 16:32:49
【问题描述】：

我正在尝试在单个页面上添加大约 20 个单独的随机生成的数字字符串，介于 55 和 999 之间，这可能吗？我尝试将元素 ID 从“randomnumber”附加到 randomnumber2、3、4、5 等...“但没有成功。有什么想法吗？

我已尝试更改此脚本以满足我的需要，但它似乎不止一次起作用。

<head>
<script type="text/javascript">
 window.onload = generateRandomNumber;
 function generateRandomNumber(){
     var n = 999;
     var number = Math.floor(Math.random()*n)+1;
 document.getElementById("randomNumber").innerHTML = number;
 }
</script>
</head>

<body>
<class id="randomNumber"></class>
</body>

已解决：

<head>

<script>
window.onload = generateRandomNumber;

     var n = 4000;
     var number = Math.floor(Math.random()*n)+1;
     var number2 = Math.floor(Math.random()*n)+1;
     var number3 = Math.floor(Math.random()*n)+1;
     var number4 = Math.floor(Math.random()*n)+1;
     var number5 = Math.floor(Math.random()*n)+1;
     var number6 = Math.floor(Math.random()*n)+1;
     var number7 = Math.floor(Math.random()*n)+1;
     var number8 = Math.floor(Math.random()*n)+1;
     var number9 = Math.floor(Math.random()*n)+1;
     var number10 = Math.floor(Math.random()*n)+1;
     var number11 = Math.floor(Math.random()*n)+1;
     var number12 = Math.floor(Math.random()*n)+1;
     var number13 = Math.floor(Math.random()*n)+1;
     var number14 = Math.floor(Math.random()*n)+1;
     var number15 = Math.floor(Math.random()*n)+1;
     var number16 = Math.floor(Math.random()*n)+1;
     var number17 = Math.floor(Math.random()*n)+1;
     var number18 = Math.floor(Math.random()*n)+1;



function generateRandomNumber(){
document.getElementById("randomNumber").innerHTML = number;
document.getElementById("randomNumber2").innerHTML = number2;
document.getElementById("randomNumber3").innerHTML = number3;
document.getElementById("randomNumber4").innerHTML = number4;
document.getElementById("randomNumber5").innerHTML = number5;
document.getElementById("randomNumber6").innerHTML = number6;
document.getElementById("randomNumber7").innerHTML = number7;
document.getElementById("randomNumber8").innerHTML = number8;
document.getElementById("randomNumber9").innerHTML = number9;
document.getElementById("randomNumber10").innerHTML = number10;
document.getElementById("randomNumber11").innerHTML = number11;
document.getElementById("randomNumber12").innerHTML = number12;
document.getElementById("randomNumber13").innerHTML = number13;
document.getElementById("randomNumber14").innerHTML = number14;
document.getElementById("randomNumber15").innerHTML = number15;
document.getElementById("randomNumber16").innerHTML = number16;
document.getElementById("randomNumber17").innerHTML = number17;
document.getElementById("randomNumber18").innerHTML = number18;

}
