如何在JavaScript中將帶有JSON對象的二維數組轉換為單個數組？

Question

在這里，我在數組中有一個JSON對象，並將其推送到employeeArray

employeeArray =[  
  [  
    {  
      "ID":"967",
      "NAME":"Dang, Lance D",
      "Email":"Lance.Dang@xyz.com"
    }
  ],
  [  
    {  
      "ID":"450",
      "NAME":"Starnes, Mitch",
      "Email":"Mitchell.Starnes@xyz.com"
    }
  ],
  [  
    {  
      "ID":"499",
      "NAME":"Cosby, Lance H",
      "Email":"Lance.Cosby@xyz.com"
    }
  ]
]; 

我如何將其放入具有這樣的JSON對象的單個數組中

employeeArray =[  
  {  
    "ID":"967",
    "NAME":"Dang, Lance D",
    "Email":"Lance.Dang@xyz.com"
  },
  {  
    "ID":"450",
    "NAME":"Starnes, Mitch",
    "Email":"Mitchell.Starnes@xyz.com"
  },
  {  
    "ID":"499",
    "NAME":"Cosby, Lance H",
    "Email":"Lance.Cosby@xyz.com"
  }
];

幫助我如何使用上述二維數組值並用純JavaScript構建我期望的數組

Answer 1

您想展平數組，可以通過reduce調用來完成：

employeeArray.reduce((p, c) => p.concat(c), [])

ES5：

employeeArray.reduce(function (p, c) {
  return p.concat(c);
}, []);
