如果我使用文本框，我沒有問題獲取數據到SQL。我想用autowrap和所有的textarea。但是當我將<input type="text" id="au_id">更改爲<textarea name="au_id">時，我無法獲得下面列出的代碼.value。textarea文本到SQL列
我只想交換多行textarea的單行文本框，仍然onclick讓我的行張貼在sql中。有些名稱/ ID對於他們的用途沒有任何意義，我從Microsoft網站複製了大部分代碼，並隨時進行更改。
代碼：
<%@ Import Namespace="System.Data.SqlClient" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Text"%>
<html>
<head>
<style type="text/css">
#au_id
