C# :webBrowser 框架网页 - 赋值 - 点击事件 - 框架网页中下拉框赋值

net框架网页中自动插入数据 ,网上搜集了一些资料

首先对webBrowser加载网页

this.webBrowser1.Url = new System.Uri("url地址", System.UriKind.Absolute);

给一般不是框架网页中的文本框赋值

webBrowser1.Document.GetElementById("文本框ID").InnerText = "weiling";//文本框赋值根据ID赋值
或者：this.webBrowser1.Document.All["文本框name"].SetAttribute("value", "0924");//文本框赋值根据name赋值

表单提交，也可以看成是一个点击事件

 HtmlElement form = webBrowser1.Document.GetElementById("formID");//提交表单
 form.InvokeMember("submit");

框架网页中的文本框赋值,"frameMain"是框架的name

webBrowser1.Document.Window.Frames["frameMain"].Document.GetElementById("txtXingming").InnerText = "521656";//框架赋值
注:frameMain 是框架的name

框架网页中下拉框赋值

HtmlDocument doc = webBrowser1.Document.Window.Frames["frameMain"].Document;//框架下下拉框赋值
HtmlElement el = doc.GetElementById("drpXingbie");
el.SetAttribute("selectedIndex", "1");

 

框架网页中文本框赋值

   HtmlElement tbUserid = webBrowser1.Document.Window.Frames[0].Document.All["username"];
            tbUserid.SetAttribute("value", "k221");

            HtmlElement tbPasswd = webBrowser1.Document.Window.Frames[0].Document.All["passwd"];
            tbPasswd.SetAttribute("value", "33311");  

            HtmlDocument htmlDoc = webBrowser1.Document.Window.Frames[0].Document;
            foreach (HtmlElement h in htmlDoc.All)
            {
                if (h.GetAttribute("type").ToString() == "submit")
                {
                    if (h.GetAttribute("value").ToString() == "确定")
                    {
                        h.InvokeMember("click");
                        break;
                    }
                }
            }

 

 

 获取框架内Html页面内容

1.获取frame的源文件

MessageBox.Show(webBrowser1.Document.Window.Frames["main"].Document.Body.InnerHtml);

2.获取frame的HTMLDocument接口

HTMLDocument doc = (HTMLDocument)webBrowser1.Document.DomDocument;
object j;
for (int i = 0; i < doc.parentWindow.frames.length; i++)
{
j = i;
HTMLWindow2Class frame = doc.parentWindow.frames.item(ref j) as HTMLWindow2Class;
if (frame.name == "main")
{                   
MessageBox.Show(frame.document.title);                    
}
}      

3.获取frame的IHTMLDocument2接口

IHTMLDocument2 doc = (IHTMLDocument2)webBrowser1.Document.Window.Frames["main"].Document.DomDocument;

4.取得frame中被点击的连接

private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
string url = webBrowser1.Document.Window.Frames["main"].Document.ActiveElement.GetAttribute("src");
}

 

 

 

webBrowser1.Navigate(new Uri("http://asd10000.com/"));

webBrowser1.ScriptErrorsSuppressed = true;
webBrowser1.AllowWebBrowserDrop = false;
webBrowser1.WebBrowserShortcutsEnabled = false;
webBrowser1.IsWebBrowserContextMenuEnabled = false;  //'屏蔽右键菜单

 

 if (webBrowser1.Document.Window.Frames == null)
                return;

            HTMLDocument doc = webBrowser1.Document.DomDocument as HTMLDocument;
            HtmlWindow window = webBrowser1.Document.Window.Frames[0];
            doc = window.Document.DomDocument as HTMLDocument;

            HTMLInputElementClass input = doc.all.item("username", 0) as HTMLInputElementClass;
            input.value = "222an1";

            input = doc.all.item("passwd", 0) as HTMLInputElementClass;
            input.value = "222111";

            HtmlDocument htmlDoc = webBrowser1.Document.Window.Frames[0].Document;
            foreach (HtmlElement h in htmlDoc.All)
            {
                if (h.GetAttribute("type").ToString() == "submit")
                {
                    if (h.GetAttribute("value").ToString() == "确定")
                    {
                        h.InvokeMember("click");
                        break;
                    }
                }
            }
