数字值正在改变，有人知道发生了什么事吗？

Question

所以我正在学习 Ember.js 并且我正在尝试显示一个数字值 (fips) 但由于某种原因它将值更改为另一个数字。我认为正在发生的事情是 ember 出于某种原因自动将数字转换为其他数字，但不确定原因。如果有人能帮我解决这个问题，我将不胜感激。提前致谢！

Javascript：

App = Ember.Application.create();

App.Router.map(function() {
  this.resource('liens', function(){});
  this.resource('portfolio', function(){});
});

App.IndexRoute = Ember.Route.extend({
  model: function(){
    return App.Liens;
  }
});

App.Liens=[
  {
          id: 1,
          apn: 'apn1',
          fips: 01700,
          state: 'CA',
          county: 'Los Angeles',
          address: 'somewhere st123',     
  },
  {
          id: 2,
          apn: 'apn2',
          fips: 01744,
          state: 'FL',
          county: 'Miami',
          address: 'someplace st700',     
  },
  {
          id: 3,
          apn: 'apn3',
          fips: 05690,
          state: 'FL',
          county: 'Orlando',
          address: 'ExactPlace in st111',   
  }
];

App.Liens = Ember.Model.extend({
  id: DS.attr('number'),
  apn: DS.attr('string'),
  fips: DS.attr('number'),
  state: DS.attr('string'),
  county: DS.attr('string'),
  address: DS.attr('string')
});

            </tr>
          {{/each}}

  </script>

</body>
</html>

我试过像这样添加控制器：

App.IndexController = Ember.Controller.extend({
  fipsCode: Ember.computed.alias('fips')
});

我在 html 中将其更改为 lien.fipsCode，但它什么都不显示

将您的数字类型更改为字符串，因为您要显示的实际上不是数值，而是仅包含数字字符的字符串。

事实上，在 javascript 中，以 0 开头的数字是八进制数的前缀 :) 这就是为什么你会得到更奇怪的值 source

数字值正在改变，有人知道发生了什么事吗？

Number value is being changed, anyone know what's going on?
