如何在JavaScript中将一个数组对象添加到另一个数组对象

Question

我的情况是：

var a=[{name:"Rambabu",id:"101"},{name:"Divya",id:"102"}];

var b=[{name:"manu",id:"103"},{name:"sudha",id:"104"}];

var c= a array + b array data objects.

预期产量：

c= [{name:"Rambabu",id:"101"},{name:"Divya",id:"102"},{name:"manu",id:"103"},{name:"sudha",id:"104"}]

Answer 1

使用.concat

 var a=[{name:"Rambabu",id:"101"},{name:"Divya",id:"102"}]; var b=[{name:"manu",id:"103"},{name:"sudha",id:"104"}]; var c = a.concat(b); console.log(c); 

或者您也可以使用传播运算符...

 var a=[{name:"Rambabu",id:"101"},{name:"Divya",id:"102"}]; var b=[{name:"manu",id:"103"},{name:"sudha",id:"104"}]; var c = [...a, ...b]; console.log(c);
