在javascript中初始化对象

Question

我有一个以这种方式填充的对象：

[...]
time: '',
age: '',
items:      {
                shirt: {selected: false, max_price: '250'},
                pants: {selected: false, max_price: '250'},
                dress: {selected: false, max_price: '250'},
                shoe: {selected: false, max_price: '250'}
            },
request: '',
[...]

我必须设置一个Schema＆＃34;模板＆＃34;准备推送到数据库并告诉每个变量期望什么类型。这就是我迷失的地方，我不知道如何使用类型来实现对象。

 [...]
age:        { type: Number},
items :         {
                        type: String:
                        {selected: type: boolean, max_price: Number} // I have no idea
                    },
request:   { type: String },
 [...]

谢谢！

Answer 1

// User class.
function User(userData) {
  this.data = userData;

  return {
    save: function() {
      // Let's use some validation library here (validatorjs, chaijs,..) to validate the input value against schema.
      someValidator(User._schema, this.data);
      ...
    }
    delete: function() {...}
  }
}

// Static (but not private) variable. To make it private, Google Search for OOP in javascript.
User._schema = {
  age:        { type: Number},
  items :         {
                         type: String:
                         {selected: type: boolean, max_price: Number} // I have no idea
                     },
  request:   { type: String },
};

// Use your object.
var newUser = new User({....});
newUser.save();
