等待webBrowser完成页面加载

问题描述

嗨！

我有问题.

我使用webbrowser类登录到某个地方.
登录该站点后，我想访问一个链接.

问题是当我登录到该位置时，它不会访问该链接.如果我在登录后和访问链接之前显示一个消息框，则该消息框有效.

代码:

Hi !

I have a problem.

I use the webbrowser class to login to a place.
After I have logged into the site, I want to visit a link.

The problem is when I have logged into the place, it won´t visit the link. If I show an messagebox after logged in and before I visit the link, it works.

The Code:

//For login: 

webBrowser3.Document.GetElementsByTagName("input")[1].InnerText = "password";
            webBrowser3.Document.GetElementsByTagName("input")[0].InnerText = "username";

webBrowser3.Document.GetElementById("selection").Focus();
            SendKeys.Send("{DOWN}");
            SendKeys.Send("{TAB}");
         SendKeys.Send("{Enter}");
//After this I being logged into the site


//After login
while (webBrowser3.ReadyState != WebBrowserReadyState.Interactive) Application.DoEvents();
         {
             Application.DoEvents();
         }

webBrowser3.Document.Links[15].InvokeMember("click");
//Clicking the link.

//如果我在最后一个链接之前放置了一个消息框，则可以访问该链接，否则我将无法登录，就像webbrowser尚未完成加载页面一样.

关于Joakim

//If I put in a messagebox before the last link, I can visit the link, otherwise I dont get logged in, its like the webbrowser hasn´t finished loading the page.

Regards Joakim

推荐答案

protected void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    if (login_initiated == true)
    {
        webBrowser3.Document.Links[15].InvokeMember("click");
    }
}
