我用prototype做的ajax查询，数量大于100时会造成IE假死。请下：）

我的代码片断
1、XML模板 
<?xml version="1.0" encoding="GB2312"?>
<print id="{T:WhoUse}">
 <!-- BEGIN printlist -->
 <info>
  <printid>{T:PrintId}</printid>
  <financeid>{T:FinanceId}</financeid>
  <contractid>{T:ContractId}</contractid>
  <printname>{T:PrintName}</printname>
  <client>{T:Client}</client>
  <printnumber>{T:PrintNumber}</printnumber>
  <unitprice>{T:UnitPrice}</unitprice>
  <totalprice>{T:TotalPrice}</totalprice>
  <contractprice>{T:ContractPrice}</contractprice>
  <contractunitprice>{T:ContractUnitPrice}</contractunitprice>
  <sendate>{T:SendDate}</sendate>
  <salesname>{T:SalesName}</salesname>
  <isaskaudit>{T:IsAskAudit}</isaskaudit>
  <saleaudit>{T:SaleAudit}</saleaudit>
  <finaceaudit>{T:FinaceAudit}</finaceaudit>
  <pmcaudit>{T:PmcAudit}</pmcaudit>
  <time>{T:Time}</time>
 </info>
 <!-- END printlist -->
</print>



2、调用的程序 
printList : function() {
		$('loading').innerHTML = this.loadingImg + ' 数据加载中。。。';
		new Ajax.Request("_quote/printlist.php",
				{ method:"get",parameters:"?randomid=" + Math.random() 
								       + "&Module="     + $F('module')
								       + "&systemid="   + $F('systemid')
								       + "&printname="  + base64encode(utf16to8($F('printname')))
								       + "&contractid=" + $F('contractid')
								       + "&financeid="  + $F('financeid')
								       + "&startdate="  + $F('startdate')
								       + "&enddate="    + $F('enddate'),

看看有没有做化的地方？

我发现你最大的问题是用了太多的string的相加,这是js最忌讳的,js的string的效率最低,你把你所有的string相加,都改成array,我想应该能解决你的问题,写个例子 
var a = []
a.push("你的内容");
a.push("你的内容2");
//等等
//最后使用时
alert(a.join(''));

这个大概是最末的一种选择。
要么直接从服务器得到你用字符串相加拼出来的表格。
要么在页面上就有一个表格让你修改。这两种方法都会比这个快。

我前一段时间也出现这个问题，不过我用的是DWR，返回给IE的数据量比楼主的大的多，等解析完全最少要15秒，我试了好几种方法。一开始我以为我的java文件写的有问题，后来发现从服务器返回到页面最多就两秒，剩下的时间全部被IE占用处理字符串了。我想问问：有没有比较好的方案？？？
