专家请帮忙~asp.net中调用JavaScript的错误

大家好。我是初学者。我要在asp.net里调用一段JavaScript check_word1()的功能，但是老是出现
编译器错误信息: BC30456: “Check_word1”不是“ASP.WebForm1_aspx”的成员。请帮我看下以下代码要怎么修改。

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="WebForm1.aspx.vb" Inherits="spelling.WebForm1"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<title>WebForm1</title>
<script language="JavaScript">

function Check_word1()
var key1, word1;
key1 = "cat";
word1 = TextBox1.text;
var times = 0;

{
var result, correct = false;

   while (times<3 && correct == false)
   {
     result = TextBox1.text;
times++;
if (result == key1)
{
correct = true;
}
      else
  {
  alert("Try again!");
  return times;

}
}
   if (correct == true)
   {
alert("You are great!");
    }
    else
    {
      alert("The correct answer is " + key1 + ".");
    }
}
</script>
<script language="vb" runat="server">
    Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
Response.Write("<script>Check_word1()</script>")
End Sub
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
btnSubmit.Attributes.Add("onclick", "return Check_word1();")
End Sub

--------------------编程问答-------------------- 你要把它RegisterStartUpScript写到客户端才可。
调用write写的时候会写到页的顶部 --------------------编程问答-------------------- 楼主似乎发了俩个帖子，
楼主可以先用vb代码进行直接验证，直接写button的click事件中做，
另我在另一个帖子中已经说了俩点~

补充：.NET技术 ,  ASP.NET
