如何在 angular 11 中合并两个或多个 arrays

Question

我有两个来自 url 的 arrays。 我正在尝试将两个 arrays 作为单个数组加入 angular

 "admin":[ { "Name":"John", "Age":34 }, { "Name:"Joe", "Age":56 } ], "users":[ { "Name":"John", "Age":34 }, { "Name:"Joe", "Age":56 } ]

我试图通过加入两个 arrays

 public newArr=[]; join(){ this.newArr=this.newArray.concat(this.admin,this.users) console.log(this.this.newArr.length); //the result shown in the console is 0 }

我尝试了另一种方法

 join(){ this.newArr.push(...this.users,...this.admins) console.log(this.newArr.length) //the results is still 0 }

请问我该怎么做 go 关于那个

Answer 1

只需使用解构赋值。 您可以在此页面获取更多信息

public newArr=[...this.admin,...this.users];

Answer 2

public newArr=[];
join(){
  this.newArr=this.admin.concat(this.users)
  console.log(this.newArr.length);
}
