使用javascript / typescript对对象中的所有数组进行排序

Question

我想对这个对象中的每个数组进行排序，目前我是以这种方式进行的

this.userInfo = {
    Interests: [],
    Websites: [],
    Games: [],
    Locations: [],
    Companies: [],
    Projects: [],
    Schools: [],
    Studies: []
};


this.userInfo.Interests.sort();
this.userInfo.Websites.sort();
this.userInfo.Games.sort();
this.userInfo.Locations.sort();
this.userInfo.Companies.sort();
this.userInfo.Projects.sort();
this.userInfo.Schools.sort();
this.userInfo.Studies.sort();

还有其他更优雅的方式吗？

Answer 1

使用Object.keys获取所有数组自身的属性名称，然后使用Array#forEach迭代键：

Object.keys(this.userInfo).forEach(function(key) {
  this.userInfo[key].sort(function(a, b) {
    // your sorting logic
  });
});

试试这个，对您有帮助，

 this.userInfo = { Interests: [2, 3, 4, 1], Websites: [2, 3, 4, 1], Games: [2, 3, 4, 1], Locations: [2, 3, 4, 1], Companies: [2, 3, 4, 1], Projects: [2, 3, 4, 1], Schools: [2, 3, 4, 1], Studies: [2, 3, 4, 1] }; for (var i in this.userInfo) { console.log(this.userInfo[i].sort()); }
