Backbone form submission, serialize the form to set in model (form field names must match model variable names)

modelAndSerializeCode.js

/*
 * MODEL CODE
 */
formSubmit: function(ev) {
    var formValues;

    ev.preventDefault();

    formValues = this.$("form").serializeObject();
    this.model.save(formValues);
}


/*
 * SERIALIZE CODE
 */
$.fn.serializeObject = function()
{
    var o = {};
    var a = this.serializeArray();
    $.each(a, function() {
        if (o[this.name] !== undefined) {
            if (!o[this.name].push) {
                o[this.name] = [o[this.name]];

        } else {
            o[this.name] = this.value || '';
        }
    });

/*
 * ADDITIONAL OPTION TO SERIALIZE FORM
 * 
 * This supports "objects" within the form data, through
 * the use of brackets to call out object attributes.
 * e.g. <input name="myObj[value1]" />
