Below is the sample code of one of the way through which you can resolve this problem. In this approach you need declare variables in JavaScript for holding server control id and then you need to use these variables inside your external JS file for attaching event.
Please let me know if you need any clarification.

ASPX page Code
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Untitled Page</title>
<script>
var tbxareaId = '<%=tbxarea.ClientID%>';

</script>

    <script src="JavaScript/jquery-1.6.1.min.js" type="text/javascript"></script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="tbxarea" runat="server"></asp:TextBox>
    </div>
    </form>

    <script src="JavaScript/JScript1.js" type="text/javascript"></script>
</body>

</html>

External Javascript JScript1.js Code

$('#' + tbxareaId).bind('click', function() {
alert('User clicked on "foo."');
});

That error can only be caused by one of below things:

    1.Your JavaScript file is not being properly loaded into your page
    2.You have JavaScript running before the page is fully loaded, and as such, before jQuery is fully loaded.

Please make sure you include Jquery js file before using Jquery function, means first include file in your page header should be Jquery JS

<head runat="server">
    <script src="JavaScript/jquery-1.6.1.min.js" type="text/javascript"></script>
</head>
