先看下這幾天作的軟件功能:javascript
-------------------分隔線-------------------------------------------------------html
軟件所使用到的WebBrowser控件全部功能:java
Navigate(string urlString):瀏覽urlString表示的網址 Navigate(System.Uri url):瀏覽url表示的網址 Navigate(string urlString, string targetFrameName, byte[] postData, string additionalHeaders): 瀏覽urlString表示的網址,併發送postData中的消息 //(一般咱們登陸一個網站的時候就會把用戶名和密碼做爲postData發送出去) GoBack():後退 GoForward():前進 Refresh():刷新 Stop():中止 GoHome():瀏覽主頁 WebBrowser控件的經常使用屬性: Document:獲取當前正在瀏覽的文檔 DocumentTitle:獲取當前正在瀏覽的網頁標題 StatusText:獲取當前狀態欄的文本 Url:獲取當前正在瀏覽的網址的Uri ReadyState:獲取瀏覽的狀態 WebBrowser控件的經常使用事件: DocumentTitleChanged, CanGoBackChanged, CanGoForwardChanged, DocumentTitleChanged, ProgressChanged, ProgressChanged DocumentCompleted 頁面加載完成以後的事件 複製代碼
一、獲取非input控件的值:web
webBrowser1.Document.All["控件ID"].InnerText; 或webBrowser1.Document.GetElementById("控件ID").InnerText; 或webBrowser1.Document.GetElementById("控件ID").GetAttribute("value");
2.獲取input控件的值:cookie
webBrowser1.Document.All["控件ID"].GetAttribute("value");; 或webBrowser1.Document.GetElementById("控件ID").GetAttribute("value");
三、給輸入框賦值:併發
//輸入框 user.InnerText = "myname"; password.InnerText = "123456"; webBrowser1.Document.GetElementById("password").SetAttribute("value", "Welcome123");
四、下拉、複選、多選:框架
//下拉框: secret.SetAttribute("value", "question1"); //複選框 rememberme.SetAttribute("Checked", "True"); //多選框 cookietime.SetAttribute("checked", "checked");
五、根據已知有ID的元素操做沒有ID的元素:函數
HtmlElement btnDelete = webBrowser1.Document.GetElementById(passengerId).Parent.Parent.Parent.Parent.FirstChild.FirstChild.Children[1].FirstChild.FirstChild;
六、獲取Div或其餘元素的樣式:post
webBrowser1.Document.GetElementById("addDiv").Style;
七、直接執行頁面中的腳本函數,帶動態參數或不帶參數都行:網站
Object[] objArray = new Object[1]; objArray[0] = (Object)this.labFlightNumber.Text; webBrowser1.Document.InvokeScript("ticketbook", objArray); webBrowser1.Document.InvokeScript("return false");
八、自動點擊、自動提交:
HtmlElement btnAdd = doc.GetElementById("addDiv").FirstChild; btnAdd.InvokeMember("Click");
九、自動賦值,而後點擊提交按鈕的時候若是出現腳本錯誤或一直加載的問題,通常都是點擊事件執行過快,這時須要藉助Timer控件延遲執行提交按鈕事件:
this.timer1.Enabled = true; this.timer1.Interval = 1000 * 2; private void timer1_Tick(object sender, EventArgs e) { this.timer1.Enabled = false; ClickBtn.InvokeMember("Click");//執行按扭操做 }
十、屏蔽腳本錯誤:
將WebBrowser控件ScriptErrorsSuppressed設置爲True便可
十一、自動點擊彈出提示框:
private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e) { //自動點擊彈出確認或彈出提示 IHTMLDocument2 vDocument = (IHTMLDocument2)webBrowser1.Document.DomDocument; vDocument.parentWindow.execScript("function confirm(str){return true;} ", "javascript"); //彈出確認 vDocument.parentWindow.execScript("function alert(str){return true;} ", "javaScript");//彈出提示 }
12.WebBrowser頁面加載完畢以後,在頁面中進行一些自動化操做的時候彈出框的自動點擊(屏蔽)
private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { //自動點擊彈出確認或彈出提示 IHTMLDocument2 vDocument = (IHTMLDocument2)webBrowser1.Document.DomDocument; vDocument.parentWindow.execScript("function confirm(str){return true;} ", "javascript"); //彈出確認 vDocument.parentWindow.execScript("function alert(str){return true;} ", "javaScript");//彈出提示 //下面是你的執行操做代碼 }
1三、獲取網頁中的Iframe,並設置Iframe的src
HtmlDocument docFrame = webBrowser1.Document.Window.Frames["mainFrame"].Document; 或 HtmlDocument docFrame = webBrowser1.Document.All.Frames["mainFrame"].Document; docFrame.All["mainFrame"].SetAttribute("src", "http://www.sufeinet.com/");
網頁中存在Iframe的時候webBrowser1.Url和webBrowser1_DocumentCompleted中的e.Url不同,前者是主框架的Url,後者是當前活動框口的Url。
1四、讓控件聚焦
this.webBrowser1.Select(); this.webBrowser1.Focus(); doc.All["TPL_password_1"].Focus();
1五、打開本地網頁文件
webBrowser1.Navigate(Application.StartupPath + @"\Test.html");
1六、獲取元素、表單
//根據Name獲取元素 public HtmlElement GetElement_Name(WebBrowser wb,string Name) { HtmlElement e = wb.Document.All[Name]; return e; } //根據Id獲取元素 public HtmlElement GetElement_Id(WebBrowser wb, string id) { HtmlElement e = wb.Document.GetElementById(id); return e; } //根據Index獲取元素 public HtmlElement GetElement_Index(WebBrowser wb,int index) { HtmlElement e = wb.Document.All[index]; return e; } //獲取form表單名name,返回表單 public HtmlElement GetElement_Form(WebBrowser wb,string form_name) { HtmlElement e = wb.Document.Forms[form_name]; return e; } //設置元素value屬性的值 public void Write_value(HtmlElement e,string value) { e.SetAttribute("value", value); } //執行元素的方法,如:click,submit(需Form表單名)等 public void Btn_click(HtmlElement e,string s) { e.InvokeMember(s); }
17。獲取Cookie
[DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)] static extern bool InternetGetCookieEx(string pchUrl, string pchCookieName, StringBuilder pchCookieData, ref System.UInt32 pcchCookieData, int dwFlags, IntPtr lpReserved); private static string GetCookieString(string url) { uint datasize = 1024; StringBuilder cookieData = new StringBuilder((int)datasize); if (!InternetGetCookieEx(url, null, cookieData, ref datasize, 0x2000, IntPtr.Zero)) { if (datasize < 0) return null; cookieData = new StringBuilder((int)datasize); if (!InternetGetCookieEx(url, null, cookieData, ref datasize, 0x00002000, IntPtr.Zero)) return null; } return cookieData.ToString(); } private void webBrowser1_DocumentCompleted_1(object sender, WebBrowserDocumentCompletedEventArgs e) { richTextBox1.Text = string.Empty; if (cbcookie.Checked) { if (checkBox1.Checked) { richTextBox1.Text = GetCookieString(textBox1.Text.Trim()); } else { richTextBox1.Text = webBrowser1.Document.Cookie; } } }
18.怎麼設置代理
/// <summary> /// 代理結構體 /// </summary> public struct Struct_INTERNET_PROXY_INFO { public int dwAccessType; public IntPtr proxy;//IP以及端口號 public IntPtr proxyBypass; }; /// <summary> /// 設置代理的Api /// </summary> /// <returns></returns> [DllImport("wininet.dll", SetLastError = true)] private static extern bool InternetSetOption(IntPtr hInternet, int dwOption, IntPtr lpBuffer, int lpdwBufferLength); /// <summary> /// 代理IP以及端口號 /// </summary> /// <param name="strProxy"></param> private void RefreshIESettings(string strProxy) { const int INTERNET_OPTION_PROXY = 38; const int INTERNET_OPEN_TYPE_PROXY = 3; Struct_INTERNET_PROXY_INFO struct_IPI; // Filling in structure struct_IPI.dwAccessType = INTERNET_OPEN_TYPE_PROXY; struct_IPI.proxy = Marshal.StringToHGlobalAnsi(strProxy); struct_IPI.proxyBypass = Marshal.StringToHGlobalAnsi("local"); // Allocating memory IntPtr intptrStruct = Marshal.AllocCoTaskMem(Marshal.SizeOf(struct_IPI)); // Converting structure to IntPtr Marshal.StructureToPtr(struct_IPI, intptrStruct, true); bool iReturn = InternetSetOption(IntPtr.Zero, INTERNET_OPTION_PROXY, intptrStruct, Marshal.SizeOf(struct_IPI)); } -------------------- RefreshIESettings("41.129.53.227:80"); webBrowser1.Navigate("http://www.sufeinet.com");
19.怎麼在加載完成某個頁面以後執行代碼
//本事件是當每次加載完成當前頁面後纔會執行的 private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { //e.Url是當前加載的頁面, if (e.Url.ToString().Contains("http://sufeinet.com")) { //執行操做1 } else if (e.Url.ToString().Contains("http://baidu.com")) { //執行操做2 } }
20.怎麼禁止在新窗口中打開網頁
private void webBrowser1_NewWindow(object sender, CancelEventArgs e) { string url = ((System.Windows.Forms.WebBrowser)sender).StatusText; webBrowser1.Navigate(url); e.Cancel = true; }
21.怎麼設置Cookie
webBrowser1.Document.Cookie=「你的Cookie值」;
