Javascript从具有最小值和最小值的数组中获取对象，需要先查找再查找对象 [英] Javascript get object from array having min value and min value is needs to find and then find object

问题描述

我在对象中的对象数组具有不同的键，所以我希望对象在该数组中具有最小值

I have array of objects in object have different key so i want the object having minimum value in that array

list = [
{
'id':4,
'name':'nitin',
'group':'angularjs'
},
{
'id':1,
'name':'nitin',
'group':'angularjs'
},
{
'id':2,
'name':'nitin',
'group':'angularjs'
},
{
'id':3,
'name':'nitin',
'group':'angularjs'
}]

我尝试过

var minValue = Math.min.apply(Math, list.map(function (o) {
                return o.id;
            }))

但是它只返回id而不是整个对象，然后我必须对get object进行更多过滤

but it returns only the id not whole object then i have to make more filter for get object

有什么直接的方法可以找到对象吗?

is there any direct method to find object?

推荐答案

您可以使用数组reduce方法:

var list = [
{
'id':4,
'name':'nitin',
'group':'angularjs'
},
{
'id':1,
'name':'nitin',
'group':'angularjs'
},
{
'id':2,
'name':'nitin',
'group':'angularjs'
},
{
'id':3,
'name':'nitin',
'group':'angularjs'
}];

var result = list.reduce(function(res, obj) {
    return (obj.id < res.id) ? obj : res;
});

console.log(result);
