Vue.js 动态映射 JSON 到 Class 而无需 vue.Set 或在 Vuex store 中直接赋值

Vue.js dynamically Map JSON to Class without vue.Set or direct assignment in Vuex store

这是一个简单的问题:"Can I map a json response to a class without specifically enumerating the fields, either with vue.set, or by passing parameters to the class, and directly assigning them?"在我看来这是可能的。

在 React 中,我可以将数据映射到 class。

-谢谢

所以: a) 我可以在 vue/vuex 中执行地图吗? (假设语法正确?) b) 我是坚持使用 vue.set 还是手动分配? c) 如果没有,是否有比 Vue-Model 更好的包?

谢谢

返回的数据:

{
    abc: "Some Text", 
    def: 9999.999, 
    ghi: false
}

需要的字段集:

function anItem(payload){
  this.abc = "";
  this.def = 0;
  this.ghi = false;
  this.notices = [];
  this.selected = false;
  this.is_updating = false;
}

突变体

const mutations = {

  setStuff (state, payload) {
    /*this.state.myList.items = payload;*/ <- this works, of course.

    this.state.mylist.items = payload.map(a => new anItem(a)) <-- syntax here?
  },

};

您可以在构造对象时使用参数作为初始值:

function anItem(payload){
  this.abc = payload.abc;  // changed this line
  this.def = payload.def;  // changed this line
  this.ghi = payload.ghi;  // changed this line
  this.notices = [];
  this.selected = false;
  this.is_updating = false;
}

然后,更改增变器以传递这样的参数:

const mutations = {

  setStuff (state, payload) {
    this.state.mylist.items = new anItem(payload);
  },

};
