是不是下面的涵数有错？
function submitProcess()
{
var detailIdObjs=document.frm.getElementsByName("pid");
for(var i=0;i<detailIdObjs.length;i++)
{
if(detailIdObjs[i].value=="")
{
alert("Please input!");
detailIdObjs[i].focus();
return false;
}
}
document.frm.submit();
}
{
document.frm.submit();
}
submitProcess里的内容是判断必须输入的，可以去掉
如果增加明细的时候下面这些代码的name属性不动态改变的话，那前面的数据岂不都被覆盖掉了？
<table id="tbDetailPrepare" style="display:none">
<tr>
<td ><input type="checkbox" name="record_select" ></td>
<td >
<select name="pid" onChange="changelist(this);">
</select>
<select name="list" onChange="changelist(this);">
</select>
<input name="pprice" type="text" id="pprice" size="12" onpropertychange="calc(this);" >*
<input name="q" type="text" id="q" size="8" onpropertychange="calc(this);" >=
<input name="result" type="text" id="result" onpropertychange=calc2();>
</td></tr>

想过这样改，不过一改就好多地方出错，昨回事？

有这回事吗?
不懂php.所以用以下方式做了下测试：
1.将form的method改成get,将其action改成aaa.htm
2.完成按钮的onclick改成document.frm.submit();
3.运行页面，添加三笔记录，点击提交
4.查看接收页的url,如下：
res://C:\WINNT\System32\shdoclc.dll/syntax.htm#unsaved:///aaa.htm?
pid=001&list=%C4%AB%BA%D0&pprice=7890.00&q=&result=0
&pid=001&list=%C4%AB%BA%D0&pprice=7890.00&q=&result=0
&pid=001&list=%C4%AB%BA%D0&pprice=7890.00&q=&result=0
&resultTotal=0数据都已传出，没见异常啊？？!!

原来你只是“想过”，但一直都没“相同ID的text做数组处理”？？？？？？
惭愧啊，俺的代码过长。
