Execute Jquery on linkbutton click

Question

I want to execute the following jquery function

$(document).ready(function () {
    $('.btnReset').click(function () {
        $('#txtFirstName').val('');
    });
});

The error is:

uncaught ReferenceError: $ is not defined.

on link button click, which is as follows;

<asp:LinkButton ID="btnReset" CssClass="btnReset" runat="server">RESET</asp:LinkButton>

But, I don't know why it is not working, Please assist me if anybody knows that. Thanks.

is #txtFirstName a client-side input (<input type="text" />), or an <asp:Textbox /> control? — pete

Actually, it is giving me an error as "uncaught ReferenceError: $ is not defined." when i tried debugging it in browser. What's this? — Learner

If $ is not defined, you are either calling the script before jQuery has loaded or jQuery is not linked to the page. — pete

@pete I tried writing the code in the head section of the page after all the scripts has been loaded, but still it is giving the same error. — Learner

asp.net changes Ids when rendering server side controls on client side, so i suspect that textbox value is not changed because of this so do like this:

$(document).ready(function () {
    $('.btnReset').click(function () {
        $("#<%=txtFirstName.ClientID%>").val('');
    });
});

I am using the client side control.

If you add runat="server" the control is server side its obvious
