code: class with javascript:::

private ClientScriptManager cs;
public LeavingPage(Page page)
{
this.page = page;
WriteJavaScipt();
}

private void WriteJavaScipt()
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
string scriptString;
scriptString = "<script language=JavaScript> " +
"string AskMsg; " +
"function LeavePage(){" +
" if(AskMsg){ " +
" ok = confirm(" + "Have you saved your changes? Click OK to Continue to the next page WITHOUT saving." + "\n" +
"Click Cancel to return to the current page." + ");" +
" if (!ok) " +
" {" +
" return false;" +
" }" +
" else" +
" { " +
" return true; " +
" } " +
" } " +
" else" +
" { " +
" return true;" +
" } " +
"} " +
"</script> ";

cs = this.page.ClientScript;

if (!cs.IsClientScriptBlockRegistered(this.GetType(), "clientScript"))
cs.RegisterClientScriptBlock(this.GetType(), "scriptString", sb.ToString());
}
}
================================================
aspx file:

<body>
<br />
<form id="form1" runat="server">
<div>
<img id= "welPage" alt = "Welcome Page" enableviewstate= "true" src="img/welcome.jpg" usemap ="#tier1"/>

<map id="tier1">
<area shape="circle" coords="330, 441, 31" href="javascript: changePage('/mainNav.ascx', '/modules/Books/UserControl1/BookNewEntry.ascx');" alt="Welcome Page" />
</map>

<script type="text/javascript" language="javascript">

function changePage(HeaderURL, BodyURL)
{
if(LeavePage())
{
if(BodyURL != '')
parent.main.location.href = BodyURL;
}
parent.header.location.href = HeaderURL;
}
</script>

</div>
</form>
<div id ="footer">

</body>
=================================================
ChangePage is suppose to load the other pages when the button in the <map> is clicked

But when it click the buttton "if(LeavePage())"
gives the error "Microsoft JScript runtime error: Object expected"
