【NET】WebBrowser执行脚本以及一般操作代码

 public class WebBrowserAssistant
     {
         System.Windows.Forms.WebBrowser wb;
         public WebBrowserAssistant(System.Windows.Forms.WebBrowser wb) {

             return this.wb.Document.GetElementById(tempEletemtTagNameAndID).GetAttribute("value");

调用

MessageBox.Show(new Huawei.PortableComputer.Util.WebBrowserAssistant(this.wbTaskList).ExeScript("$j('.listContentTable td :checkbox:checked:first').parent().next().next().next().text()"));
