Add Same Rule Multiple Fields

I'm trying to add the same rules to html input elements with this naming convention:

name="elements[1]"
name="elements[2]"

I'm using jQuery and jQuery Validation Plugin:

var elements = $("#elementsFieldset :input");
$.each(elements, function(i, element) {
    element.rules('add', {
    required: true,
    number: true
});

But I'm afraid that element is not the kind of object jQuery expects for adding rules. I'm receiving:

Uncaught TypeError: Object #<HTMLInputElement> has no method 'rules'

Many thanks for any help.

Use $(this) instead of element.

element is HTML JavaScript Object.

to add rules you need jQuery Object i.e $(this)

var elements = $("#elementsFieldset :input");
$.each(elements, function(i, element) {
    $(this).rules('add', {
    required: true,
    number: true
});

or even better 

var elements = $("#elementsFieldset :input");
    elements.each(function(){
        $(this).rules('add', {
        required: true,
        number: true
    });

Updated

Below code works for one element only if you want to apply rule for more than one element use .each() as used in above example.

$("#elementsFieldset :input").rules("add", { 
  required:true,  
  number:true
});

Try this,

$.each(elements, function(i, element) {
    $(this).rules('add', {// use $(this) instead of element
    required: true,
    number: true
});

or try it simply,

$("#elementsFieldset :input").rules("add", { 
  required:true,  
  number:true
});

You can add rule on a class See jQuery Validation using the class instead of the name value
