如何将一个对象数组放入另一个对象？

Question

我有一个JavaScript数组，copyCommands，我想推入一些项目。但是，我似乎无法正确添加另一个项目数组到父对象autoGenData。

//autoGenData is the object, copyCommands is an array 

     autoGenData.copyCommands.push({ 
      CopyFrom: UnitFrom, 
      //CopyTo: //array that needs to hold CopyOptions and Unit 
     }); 

      //Need to add these into CopyTo 
      //CopyOptions: checkedItems, 
      //Unit: localUnitTo 

什么是添加CopyOptions和unit到push命令CopyTo部分正确的语法？

Answer 1

我认为你正在寻找的东西是这样的：

autoGenData.copyCommands.push({ 
    CopyFrom: UnitFrom, 
    CopyTo: { 
    CopyOptions: checkedItems, 
    Unit: localUnitTo 
    } 
}); 

Answer 2

你可以尝试以下方法：

var x = [1, 2, 3, 4]; 
var y = [5, 6, 7]; 
x.push(...y);
