通过注入脚本实现查看选中内容HTML源代码的功能【目前似乎只有遨游支持此功能，调试页面时很轻盈好用的功能】
1 private void MainForm_Load( object sender, EventArgs e) 2 { 3 wbMain.ObjectForScripting = this ; 4 wbMain.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(wbMain_DocumentCompleted); 5 } 6 7 void wbMain_DocumentCompleted( object sender, WebBrowserDocumentCompletedEventArgs e) 8 { 9 InjectGetSelection(); 10 } 11 12 private void InjectGetSelection() 13 { 14 string js = " function kai_GetSelect(){return document.selection.createRange().htmlText;} " ; 15 // js += " function kai_Delete(){var ele = document.getElementById('jsInject'); ele.parentNode.removeChild(ele);} "; 16 InjectJS(js); 17 } 18 19 private void InjectJS( string js) 20 { 21 var ele = wbMain.Document.CreateElement( " script " ); 22 ele.SetAttribute( " text " , js); 23 ele.Id = " jsInject " ; 24 wbMain.Document.Body.AppendChild(ele); 25 } 26 27 private void btnViewSelected_Click( object sender, EventArgs e) 28 { 29 if (wbMain.Document == null ) 30 return ; 31 32 object obj = wbMain.Document.InvokeScript( " kai_GetSelect " ); 33 if (obj != null ) 34 txtHtml.Text = obj.ToString(); 35 else 36 txtHtml.Text = "" ; 37 // wbMain.Document.InvokeScript("kai_Delete"); 38 }
