Question

JS里对象的值如何加属性呢？

比如对象：
var object1 ={"1": "张三","2": "李四"};
要怎么写才能变为在前面添加id和name属性变为：
var arr =[
{"id":"1","name": "张三"},
{"id":"2","name": "李四"},
];

Answer 1

var object1={"1": "张三","2": "李四"};
var arr=Object.keys(object1).map(function(k){
   return {id:k,name:object1[k]};
});
console.log(arr);
