Creation my own plugin for form validation

Creation my own plugin for form validation

I am trying to develop a validation plugin to validate forms using jquery, but I can´t to execute some action after a successful validation, I don't know how to return a value from my plugin or to execute a callback after a successful validation.

jquery_validacion_form.js

(function($){ $.fn.extend({ validate:function(){ var success=true; return this.each(function() //var $this=$(this); if($(this).attr('class')=='required'){ if($(this).val()==''){ $(this).css('border','1px solid #FF0000'); success=false; } else{ $(this).css('border','1px solid #CCCCCC'); } } }); return success; } }); })(jQuery);
