关于动态的在form中插入行列的问题

Question

function addItem(tblname) {
var newRow;
var newCell; newRow = document.all[tblname].insertRow(); newCell = newRow.insertCell();
newCell.insertAdjacentHTML("BeforeEnd","<input type='text' name='ip_no' size='9' maxlength='6' value><input type='hidden' name='low' value>");

}没时间了,要下班了,这是以前写的ASP中的一段javascript.可以参照.

Answer 1

<form id=form1>
<input type=text>
</form>
<input type=button value="add" onclick="form1.innerHTML=form1.innerHTML+'<input type=text size=30 >';savedata();" >
<input type=hidden value="" id=formdata>
<script>
window.onload=getdata;//切换回时读出数据
window.onbeforeunload=savedata;//换到别的页面之前进行保存
function getdata(){
  if(formdata.value){form1.innerHTML=formdata.value}
}
function savedata(){
  formdata.value=document.all.form1.innerHTML;
}

Answer 2

我忘了我们当时迁移前,必须保存画面数据到数据库,迁移返回时,从数据库LOAD数据.
不好意思..

Answer 3

数据不大的话，在ONUNLOAD事件处理函数里用COOKIE记住数据，等回到该页面时，如
果有数据，在ONLOAD再动态生成这些行列，并从COOKIE里取出数据，放进这些行列
里
