【NET】WebBrowser执行脚本以及一般操作代码
1 public class WebBrowserAssistant 2 { 3 System.Windows.Forms.WebBrowser wb; 4 public WebBrowserAssistant(System.Windows.Forms.WebBrowser wb) { 5 this.wb = wb; 6 } 7 public bool SetElementValue(string id,string value) { 8 this.wb.Document.GetElementById(id).SetAttribute("value", value); 9 return true; 10 } 11 12 public object InvokeScript(string scriptName) { 13 return this.wb.Document.InvokeScript(scriptName); 14 } 15 public object InvokeScript(string scriptName,object[] ps) 16 { 17 return this.wb.Document.InvokeScript(scriptName, ps); 18 } 19 public void GetFocus(string id) 20 { 21 this.wb.Document.GetElementById(id).Focus(); 22 } 23 public void GetBlur(string id) 24 { 25 this.wb.Document.GetElementById(id).RemoveFocus(); 26 } 27 public string GetInputIDByName(string name) 28 { 29 return GetInputIDByName(name, name); 30 } 31 32 public void ClickElement(string id) { 33 this.wb.Document.GetElementById(id).InvokeMember("click"); 34 } 35 public string GetInputIDByName(string name,string id) 36 { 37 System.Windows.Forms.HtmlElementCollection es = this.wb.Document.GetElementsByTagName("input"); 38 if (es != null && es.Count > 0) { 39 System.Collections.IEnumerator ie = es.GetEnumerator(); 40 System.Windows.Forms.HtmlElement e; 41 while (ie.MoveNext()) { 42 e = (System.Windows.Forms.HtmlElement)ie.Current; 43 if (e.Name.Equals(name)) 44 { 45 if (string.IsNullOrEmpty(e.Id)) 46 { 47 e.Id = id; 48 } 49 return e.Id; 50 } 51 } 52 } 53 return null; 54 } 55 56 public List<string> GetEletemtByName(string name) 57 { 58 System.Windows.Forms.HtmlElementCollection es = this.wb.Document.GetElementsByTagName("input"); 59 if (es != null && es.Count > 0) 60 { 61 List<string> result = new List<string>(); 62 System.Collections.IEnumerator ie = es.GetEnumerator(); 63 System.Windows.Forms.HtmlElement e; 64 while (ie.MoveNext()) 65 { 66 e = (System.Windows.Forms.HtmlElement)ie.Current; 67 if (e.GetAttribute("type").Equals("checkbox") && e.Name.Equals(name) && e.GetAttribute("checked").Equals("True")) 68 { 69 result.Add(e.GetAttribute("value")); 70 } 71 } 72 return result; 73 } 74 return null; 75 } 76 public string ExeScript(string scriptBlock) { 77 return ExeScript(scriptBlock, "tempEletemtTagNameAndID"); 78 } 79 public string ExeScript(string scriptBlock,string tempEletemtTagNameAndID) { 80 System.Windows.Forms.HtmlElement ele; 81 if (this.wb.Document.GetElementById(tempEletemtTagNameAndID) == null) { 82 ele = this.wb.Document.CreateElement(tempEletemtTagNameAndID); 83 ele.Id = tempEletemtTagNameAndID; 84 this.wb.Document.Body.AppendChild(ele); 85 } 86 ele = this.wb.Document.CreateElement("script"); 87 ele.SetAttribute("type", "text/javascript"); 88 89 ele.SetAttribute("text", string.Format("$j(\"#{0}\").val({1})", tempEletemtTagNameAndID, scriptBlock)); 90 this.wb.Document.Body.AppendChild(ele); 91 92 return this.wb.Document.GetElementById(tempEletemtTagNameAndID).GetAttribute("value"); 93 } 94 95 }
