user_form.html

<form>
  Name: <input type="text" name="name"/>
  Age: <input type="text" name="age"/>
  <input type="submit" value="Submit"></input>
</form>

user_form.js

var UserForm = Backbone.View.extend({
  events: {'submit': 'save'},
 
  initialize: function() {
    _.bindAll(this, 'save');
  },
   
  save: function() {
    // http://api.jquery.com/serializeArray/
    var arr = this.$el.serializeArray();
    // This accumulates the name/value hashes into a single hash which is much easier to submit to forms
    var data = _(arr).reduce(function(acc, field) {
      acc[field.name] = field.value;
      return acc;
    }, {});
    this.model.save(data);
    return false;
  }
});
 
var userForm = new UserForm({el: this.$('form'), model: new User()});
