MSHTML - 自动点击JavaScript确认对话框 [英] MSHTML - Auto Click for JavaScript confirm dialog

问题描述

我正在尝试使用MSHTML自动解析/提交网页（在C＃.Net 3.1 WPF WebBrowser控件中）。我可以填写表单，点击按钮和导航页面，而不会出现问题。

I am trying to automatically parse/submit a web page using MSHTML (in C#.Net 3.1 WPF WebBrowser control). I can fill the forms, click buttons, and navigate pages without problems.

但是我不知道如何自动点击JavaScript确认对话框上的确定按钮当我点击提交按钮时出现。

But I do not know how to automatically click the "OK" button on the JavaScript confirmation dialog which appears when I click the "Submit" button.

C＃代码：

mshtml.IHTMLDocument2 doc = (mshtml.IHTMLDocument2)webBrowser.Document;
mshtml.IHTMLFormElement form = doc.forms.item("inputForm", 0) as mshtml.IHTMLFormElement;
mshtml.IHTMLElement btnSubmit = form.item("btnFormSubmit", null) as mshtml.IHTMLElement;
btnSubmit.click();

出现确认对话框（Are you sure？）。
我想以某种方式向MSHTML文档发送Enter按键以自动确认提交。

The confirmation dialog ("Are you sure?") appears. I want to somehow send an "Enter" keystroke to the MSHTML document to automatically confirm the submission.

推荐答案

我终于找到了自己如何在WebBrowser控件中抑制确认消息的方式。它实际上在javascript函数showConfirm（）中显示。我将虚拟函数showConfirm（）放在Browser.Document的头部顶部，该文档覆盖/禁止原始函数showConfirm（）。代码很忙，但主要思想很清楚，而且工作完美。

I finally found myself the way how to suppress confirmation message in WebBrowser control. It is actually shown in javascript function showConfirm(). I insert dummy function showConfirm() at the top of the header of the Browser.Document which overwrites/suppress the original function showConfirm(). The code is busy, but the main idea is clear, and works perfect.
