JqueryUI spinner numberformat currency submit number value

I have a jquery currency input and I am using this code:

$('input[name="precio"]').spinner({
    min:0,
    numberFormat: 'C'
});

The input works perfectly as it shows the number as a number with the $ or € sign depending on globalize.

The problem is that when I submit the form I get the text like this "5,00 €" and I would like it to be 5.00 or 500, just the number value.

Is there any way to do this? Thanks in advance.

Ok I finnaly managed to do this the way I wanted. I've just created a plugin named currencyspinner that extends spinner from JQueryUI, here is the code:

$.widget( "ui.currencyspinner", $.ui.spinner, {
     options: {
        numberFormat: 'C',  // Currency Format
        min:0,
        step:0.10
    },
    _create: function(){
        this.hidden = $('<input type="hidden" value="'+this.element.val()+'" name="'+this.element.attr('name')+'">');   // Create a hidden input with the same name and value
        this.element.removeAttr('name');    // remove the name of the original element
        this.element.before(this.hidden);   // insert the hidden element before the original element
        return this._super();
    },

    _refresh: function() {
        this.hidden.val(this._parse(this.element.val()));   // put the aria-valuenow on the original element
        return this._super();
    },

    _destroy: function(){
        this.element.attr('name',this.hidden.attr('name')); // put back the name on the original value
        this.hidden.remove();                               // remove the hidden element
        return this._super();
    }
});

I create a hidden input with the same name and give it the value of aria-valuenow each time the spinner refreshes.

BE CAREFUL if you are trying to acess the currencyspinner after creating the currencyspinner you cannot use $('input[name="nameoftheelement"]').currencyspinner(...); as this will be the hidden input and not the spinner itself.

I Hope it helps someone!
