Question

I’m still pretty new to jQuery! Testing it out on my old website to test out it’s function. I can’t even get a simple jQuery script to run and it’s terribly embarrasing. Please help guys!

For some reason, I can’t get the jQuery selector to find element by id. Here’s the code

 $(document).ready(function () {
        if (jQuery) {
            alert("jQuery working");
        } else {
            alert("jQuery not working");
        }

        $('#TextBox4').keyup(function () {
            alert("KEYUP FUNCTION WORKENGGG");
            var password = jQuery('#TextBox3').val();
            var cfmPassword = jQuery('#TextBox4').val();
            check_password_match(password, cfmPassword);
        });
    });

And this is my ASP html code.

<asp:TextBox ID="TextBox4" runat="server" BackColor="#181818" ForeColor="White" 
                        TextMode="Password" ToolTip="Password">Password</asp:TextBox>`

<asp:TextBox ID="TextBox3" runat="server" BackColor="#181818" ForeColor="White" 
                        TextMode="Password" ToolTip="Password" Height="22px">Password</asp:TextBox>`

Try this:
$('#<%=TextBox4.ClientID %>')

On client side asp.net controls have id different than what you give it in aspx page.
