    $("#your-text-area").bind('keyup', function(event) {
        var String = $("#your-text-area").val()

           if (String.length >= minLength )  {  
                $(".submit-name").removeAttr("disabled");
            } else {
                $(".submit-name").attr("disabled", "true");        
            }
