为什么我的asp代码加载后，打开页面速度很慢
这是一个动态添加行的js调用，在js里又调用了下面这一段，我测试了，就是因为StrTemp（红色部分）的加载，打开页面速度特别慢，可是我不知道怎么改合适。请高手指教js：
<script type="text/javascript">
var ii=0;
function addTable()
{
ii=ii+1;
var tab = document.getElementById("tb1") ;
//表格行数
var rows = tab.rows.length ;
if(rows<=8)
{
newTr=document.getElementById("tb1").insertRow();
var newTd0 = newTr.insertCell();
var newTd1 = newTr.insertCell();
var newTd2 = newTr.insertCell();
var newTd3 = newTr.insertCell();
var newTd4 = newTr.insertCell();
var newTd5 = newTr.insertCell();
