代码样例

<!DOCTYPE html>
<html>
<head>
<style type="text/css">
*{margin:0;padding:0;}
td {text-align:center;}
tr {text-align:center;}
th {text-align:center;}
</style>
</head>
<body>
<script type="text/javascript"> 

$(document).ready(function(){

var errorcount = document.getElementById('errorcount').innerText;
var erroravg = document.getElementById('erroravg').innerText;

var longtime = document.getElementById('longtime').innerText;
var longtimeavg = document.getElementById('longtimeavg').innerText;




//强制转换为数值型
