ASP检查请求方法 [英] ASP check request method

问题描述

如何检查我的表单是否已在经典 ASP 中提交?

How do i check if my form has been submitted in classic ASP?

推荐答案

首先，您可以检查，如果 Request.ServerVariables("REQUEST_METHOD")= "POST".即假设你使用POST方式提交表单，初始加载会有GET方式，后续提交都是POST方式.

First, you can check, if Request.ServerVariables("REQUEST_METHOD")= "POST". That is, assuming, you use POST method to submit the form, the initial load will have GET method, the subsequent submits will be POST.

您也可以在表单中添加隐藏字段，如果该变量设置在 POST 数据中(Request.Form 对象)，您将知道这是回发，否则是第一次加载.

You can also add a hidden field in your form, if that variable is set in POST data (Request.Form object), you will know it is a postback, otherwise it is the first load.
