javascript function

问题

I can't call my javasript using a freetextbox in asp.net.

here's code my in javascript:

function validateFreetextbox()

{

    if(document.FTB_API["txt_Decs"].GetHtml == ''  )   

     {
        alert("Please Fill up desciption.");
        return false;
    }
    else
    {
        return true;
    }
}

my code's in asp.net for button:

<asp:Button ID="btn_Add" runat="server" OnClick="btn_Add_Click" Text="Add" 

Width="231px" Font-Size="11px" Font-Bold="false" ForeColor="#333333"  

onclientclick=" validateFreetextbox()" />

回答1:

should be onclientclick="validateFreetextbox();"

Edit: for your help, I have just created page at my end try and its working... can you make new page and check this at your end...

<html xmlns="http://www.w3.org/1999/xhtml">

<script language="javascript" type="text/javascript">
function validateFreetextbox()
{
alert('Called');
//    if(document.FTB_API["txt_Decs"].GetHtml == ''  )   
//    {
//        alert("Please Fill up desciption.");
//        return false;
//    }
//    else
//    {
//        return true;
//    }

}

</script>

</head>
<body>
    <form id="form1" runat="server">
        <div>
            <asp:Button ID="btn_Add" runat="server"  Text="Add" Width="231px"
                Font-Size="11px" Font-Bold="false" ForeColor="#333333" OnClientClick="validateFreetextbox()" OnClick="btn_Add_Click" />
        </div>
    </form>
</body>
</html>
