我必须修改旧的 ASP 页面以允许用户更新他们列出的电话号码,这些电话号码存储在 SQL 2005 数据库中。该页面的代码看起来非常繁重,因此我为它的密度道歉。用户在表单中输入名称并被定向到以下结果页面:

我将如何允许用户更新“Ext”字段?
最初,我用一个简单的两字段表单制作了一个模态窗口。我似乎无法在不丢失大部分代码的情况下将代码粘贴到此处。它的字段被赋予标签和 ID 'FullName' 和 'Ext'。
该表单使用 Get 方法将捕获的信息发送到下一页 action=phoneresults.asp,它本质上是同一页。在该页面上,我有以下更新查询:
<%
Dim FullName, Ext
Dim sConnString, connection, sSQL
FullName = Request.Form("FullName")
Ext = Request.Form("Ext")
sSQL = "INSERT into dbo.telephone.staffdetails (FullName, Ext) values ('" & FullName & "', '" & Ext & "')"
%>
模态窗口实际上没有必要。这只是突然出现(出现?)的第一种更新方式。在网上看了很长时间,我开始怀疑这是否真的是最简单的方法;是不是太复杂了?
我的更新查询大概是巨大的,我猜也是,我试图给它所需的信息的方式。我为此道歉。在网上搜索,我正在处理的代码似乎也非常古老。
