javascript - 根据其他属性(语言)更改 JavaScript 属性

Question

我想根据语言使用 JavaScript 更改对象 department_descr:

var data = {
  "language": "EN",    
  "contacts": [
    {
      "department_descr": {
        "en": "Management",
        "fr": "Gestion"
      }
    }
  ]
};

输出:

{  
  "language": "EN",  
  "contacts": [
    {
      "department_descr": "Management"
    }       
  ]
}

Answer 1

首先，您的示例对象格式错误，这将导致语法错误。将其更改为:

var data = {
  "language": "EN",    
  "contacts": [
      {
        "department_descr": {
          "en": "Management",
          "fr": "Gestion"
        }
      }
  ]
}

其次，在这种情况下不建议更改对象。您应该使用您需要的模型创建一个新对象:

var desc = data.contacts[0].department_descr[data.language.toLowerCase()];
var newData = Object.assign({}, data, { contacts: [ { department_descr: desc } ] })
