问题描述
我在这里遇到了问题.我已经创建了一个用于将记录添加到数据库中的页面,它工作正常但是每次加载页面时都会运行 asp 脚本,每次加载页面时都会向数据库输入一条空白记录,这很烦人,因为它搞砸了我有其他脚本.我觉得我很愚蠢,但我只需要在单击提交按钮后才运行脚本,我该如何让它做到这一点?
I'm having a problem here. I've created a page for adding records into a database, it's working fine however the asp script is running every time the page loads, inputting a blank record to the database each time the page is loaded, this is very annoying as it messes with other scripts I have. I feel I am being very stupid but all I need is for the script to run only once the submit button has been clicked, how do I get it to do this?
<!DOCTYPE html>
<html>
<title>

推荐答案
给你的提交输入一个名称属性 - 例如提交按钮 - 然后做类似的事情
Give your submit input a name attribute - eg submitbutton - then do something like
if request.form("submitbutton") <> "" then
'put your insert code here
End if
