Page.ClientScript.RegisterOnSubmitStatement測試

請參考HOW TO：以動態方式將用戶端指令碼加入至 ASP.NET Web 網頁

WebForm1.aspx

  1: <html xmlns="http://www.w3.org/1999/xhtml">
  2: <head runat="server">
  3:     <title></title>
  4:     <script type="text/javascript" src="script/check.js"></script>
  5: </head>
  6: <body>
  7:     <form id="form1" runat="server">
  8:     <div>
  9:     <input type="submit" />
 10:     </div>
 11:     </form>
 12: </body>
 13: </html>

check.js

  1: function check1() {
  2:     return confirm('submit this page?');
  3: }

WebForm1.aspx.cs

  1:         protected void Page_Load(object sender, EventArgs e)
  2:         {
  3:             Page.ClientScript.RegisterOnSubmitStatement(this.GetType(),
  4:                 "SubmitState1",
  5:                 "check1();");
  6:         }
  7:

Html Source Code

  1: <html xmlns="http://www.w3.org/1999/xhtml">
  2: <head><title>
  3: 
  4: </title>
  5:     <script type="text/javascript" src="script/check.js"></script>
  6: </head>
  7: <body>
  8:     <form method="post" action="WebForm1.aspx" onsubmit="javascript:return WebForm_OnSubmit();" id="form1">
  9: 
 10: <script type="text/javascript">
 11: //<![CDATA[
 12: function WebForm_OnSubmit() {
 13: check1();
 14: return true;
 15: }
 16: //]]>
 17: </script>
 18: 
 19:     <div>
 20:     <input type="submit" />
 21:     </div>
 22:     </form>
 23: </body>
 24: </html>

除了以JS檔引入之外，也可以在.aspx.cs中直接使用JS Code。


WebForm1.aspx.cs

  1:         protected void Page_Load(object sender, EventArgs e)
  2:         {
  3:             string confirmScript = @"return confirm('submit this page?');";
  4: 
  5:             Page.ClientScript.RegisterOnSubmitStatement(this.GetType(),
  6:             "SubmitState1",
  7:             confirmScript);
  8:         }
