Javascript space function
<p>I have a JS code that the function is to validate the form, now what I want to do is add 1 function to prevent space in textbox username with message too, "No space allowed". Here it's my JS code so far :</p>

<pre><code>$().ready(function()
    {
        $("#signupForm").validate(
        {
            rules:
            {
                full_name: "required",
                username: {
                    required: true,
                    minlength: 2
                },
                password: {
                    required: true,
                    minlength: 5
                },
                email: {
                    required: true,
                    email: true
                },
            },
            messages:
            {
                full_name: "Please enter your full name",
                username:
                {
                    required: "Please enter a username",
                    minlength: "Your username must consist of at least 2 characters"
                },

                password:
                {
                    required: "Please provide a password",
                    minlength: "Your password must be at least 5 characters long"
                },

                email: "Please enter a valid email address"
            }
        });
    });
</code></pre>

<p>Anyone can give me idea ?
Thanks.</p>
