从对象数组中获取属性数组

Question

Say i have an array of objects in javascript as假设我在 javascript 中有一个对象数组

var array=[{id:1,message:"hello",time:"00-00-0000"},{id:2,message:"sup",time:"00-00-0000"},...];

What is the best way to get an array only containing the message attribute.获取仅包含消息属性的数组的最佳方法是什么。 ie IE

var messages=["hello","sup",...];

Answer 1

The "best" way would be: “最好”的方式是：

var messages = array.map(function(x) {return x.message;});

The most compatible way:最兼容的方式：

for(var messages=[],i=0,l=array.length; i<l; i++) messages[i]=array[i].message;

Answer 2

var messages = [];

for(var i = 0; i < array.length; i++) {
    messages.push(array[i][1]);
}

Answer 3

@Niet the Dark Absol 解决方案的更简洁、更现代的变体是：

const messages = array.map(x => x.message);
