Usage

ProtoformClass utilise the field elements id attribute to indicate the validation requirements (through suffixes).

The title attribute of the form fields (to be valitated) is used to show an error message; assign an id to each of these fields with your prefix and the type of validation desired.

If You want, customize form stylesheets, loading, errors and response message (div.protoform-message ul.error, p.working, inserted by the script).

Event.observe(window,"load",function() {    		
	new Protoform('myform', { ajax:false });
	$$("form.myotherforms").each(function(forms){ 
    		new Protoform(forms);     
	});
});

Options

Class options:

  • ajax: enable or disable submit in ajax (default 'true').

  • url: Path of the file that processes the form data (optional, to overwite the form action in the ajax call)
  • messageContainer: the classname of the container-box for error message and ajax response (default 'protoform-message')
  • messagePosition: the position of the error message and ajax response (default 'before')
