将JavaScript数组的键和值获取到变量中

问题描述

我有一个JavaScript对象数组.写入console.log(myarry)时，它将以以下形式显示在控制台中.

I have a JavaScript object array. When write console.log(myarry) it will show in the console in the below form.

Array[2]
0: Object
one: "one"

1: Object
two: "two"
length: 2

在此数组中，我的键和值相同，并且正在尝试将键或值获取到变量中并进行打印.当尝试下面的代码时，它显示:

In this array my key and value are same and am trying to get the key or value to a variable and print it. When am trying the below code it showing:

for (var key in myarry) {
 alert("Key is " + key + ", value is" + myarry[key]);
}

推荐答案

检查此代码段

var obj = [{
  "1": "one"
}, {
  "2": "two"
}]
obj.forEach(function(item) {
  Object.keys(item).forEach(function(key) {
    console.log("key:" + key + "value:" + item[key]);
  });
});
