how to limit the number of characters
<p>i need to control the numer of characters enter by the user on a single textbox, but i don't know how, for example y have this</p>

<pre><code>$.validator.addMethod('selectNone',
                    function(value, element) {
                        return this.optional(element) ||
                        (value.indexOf(" ") == -1);
                    }, "Por Favor Selecciona una Opción");
</code></pre>

<p>how can i create a rule that control that the use just enter 6 characters (alfanumeric) and how can i control that the user can enter max a number 999,999,999.99 (i can control that the user if doesnt enter the "," and my textbox add it when the user finish a number like 55555.55 and transform it to 55,555.55 (the "." should be always entered by the user if they are going to enter decimals)</p>

<p>thanks</p>
