如何在 angular 11 中合並兩個或多個 arrays

Question

我有兩個來自 url 的 arrays。 我正在嘗試將兩個 arrays 作為單個數組加入 angular

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

我試圖通過加入兩個 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 }

我嘗試了另一種方法

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

請問我該怎么做 go 關於那個

Answer 1

只需使用解構賦值。 您可以在此頁面獲取更多信息

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

Answer 2

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