Javascript 在主干网中将数据从一个模型传递到另一个模型

问题：我想创建一个新的模型，该模型获取这个值mynumber并进行POST请求。到目前为止，我有：

$("#button").click(function(){
  var mynumber = $("#one").val() + $("#two").val() + $("#three").val();
  //IF i do a this.model.save here it will POST all four fields that I dont want
});

我不知道如何将这两者联系起来。我只想发布我的编号，而不是所有的字段。如果有任何帮助，我们将不胜感激

var mymodel = Numbermodel.extend({
  this.model.set(mynumber);
  this.model.save({},{
    success: function(model, response) {
      console.log('success! ' + response);
    },
    error: function(model, response) {
      console.log('error! ' + response);
    }
  });
});

将该代码与html代码一起使用

我的POST请求仍然包含一、二、三、四和我的号码。我可以在设置为mynumber之前销毁模型吗？感谢you@James添加到end

返回false

sentRequest

var mymodel = Numbermodel.extend({
  this.model.set(mynumber);
  this.model.save({},{
    success: function(model, response) {
      console.log('success! ' + response);
    },
    error: function(model, response) {
      console.log('error! ' + response);
    }
  });
});

var FormView = Backbone.View.extend({
      tagName: 'form',
      events: {
          'click #button': 'sentRequest'
      },
      initialize: function(){
         ...
      },
      render : function(){
         ...
      },
      sentRequest: function(){
          var mynumber = $("#one").val() + $("#two").val() + $("#three").val();
          var mymodel = new Numbermodel();
           model.set(mynumber);
           model.save({},{
              success: function(model, response) {
                  console.log('success! ' + response);
               },
              error: function(model, response) {
                  console.log('error! ' + response);
              }
          });
          return false;   //return false -- with the code form request does not send 
      }
})
$(function(){
    var view = FormView();
    view.render();

});
