如何将对象转换为数组？(How to convert an object into an array?)

如何将对象转换为数组？(How to convert an object into an array?)

我有对象数组，我想将数组更改为删除对象。

我的目标是：

[{ABC: "ELEMENT1", MAX: 2, MIN: "Yes"}, {ABC: "ELEMENT2", MAX: 1, MIN: "Yes"}]

我想要像索引数组的结果：

[{"ELEMENT1",2,"Yes"},{"ELEMENT2",2,"Yes}]

I have array of object and I want to change into array an remove object.

My object is like:

[{ABC: "ELEMENT1", MAX: 2, MIN: "Yes"}, {ABC: "ELEMENT2", MAX: 1, MIN: "Yes"}]

and I want result like array with index:

[{"ELEMENT1",2,"Yes"},{"ELEMENT2",2,"Yes}]

在Object.keys(obj)使用Array#map

Object.keys()方法返回给定对象自己的可枚举属性的数组。

map()方法创建一个新数组，其结果是在此数组中的每个元素上调用提供的函数。

var ip = {
  STU: "Study1",
  SUB: 2,
  EXL: "Yes"
};
var op = Object.keys(ip).map(function(key) {
  return ip[key];
});
console.log(op); 
  
 
 
 迭代Array-of-Objects 
 
 
 
  
  
var ip = [{
  STU: "Study1",
  SUB: 2,
  EXL: "Yes"
}, {
  STU: "Study2",
  SUB: 4,
  EXL: "No"
}];
var op = ip.map(function(item) {
  return Object.keys(item).map(function(key) {
    return item[key];
  });
});

console.log(op); 
  
 
 
 
Use Array#map over Object.keys(obj)
 
 
The Object.keys() method returns an array of a given object's own enumerable properties.
 
The map() method creates a new array with the results of calling a provided function on every element in this array.
 
 
 
  
  
var ip = {
  STU: "Study1",
  SUB: 2,
  EXL: "Yes"
};
var op = Object.keys(ip).map(function(key) {
  return ip[key];
});
console.log(op); 
  
 
 
To iterate Array-of-Objects
 
 
 
  
  
var ip = [{
  STU: "Study1",
  SUB: 2,
  EXL: "Yes"
}, {
  STU: "Study2",
  SUB: 4,
  EXL: "No"
}];
var op = ip.map(function(item) {
  return Object.keys(item).map(function(key) {
    return item[key];
  });
});

console.log(op);
