在開發asp.net應用程序過程中編寫Script是件很煩人的事情,其實我們可以把常用的Script裝成相應的.NET組件在服務端調用,這樣可以大大簡化Script的編寫還提高的Script的重用.
以下是常用的打開模式窗體并獲取返回值的類調用，實際上可以給設置多個參數傳入和不同控件獲取不同返回值的結果．
定義打開窗體并設置返回值腳本類.
Hfsoft.Web.Scripts.ShowModalDialog dialog=new HFSoft.Web.Scripts.ShowModalDialog(
XXX.Units.Config.WebBoot+"Appunit/WindowOpenDialog.aspx",
FrmFailureLogSearch.PageURI());
dialog.Height=400;
dialog.Width=600;
dialog.ReturnElements.Add(new HFSoft.Web.Scripts.ReturnElement(this.txtReturn.ClientID,"ReturnString"));
HFSoft.Web.Scripts.RegisterScript.RegiOnClick(cmdSearch,dialog);
打開窗體設置返回值的代碼
HFSoft.Web.Scripts.ReturnValues returnValue=new HFSoft.Web.Scripts.ReturnValues();
returnValue.Add("ReturnString",filter);
HFSoft.Web.Scripts.RegisterScript.RegiPageClient(this,"return",returnValue);
打開窗體類的代碼（其實很多Script都可以通過這樣的方式來封裝）．
