我正在尝试根据多个值report_yr和report_qtr对下面的数组进行排序,
数组应首先按年份排序,然后再按季度(同一年)排序。
//输入数组
let arr = [{
report_yr: '2008',
report_qtr: '1'
},
{
report_yr: '2019',
report_qtr: '3'
},
{
report_yr: '2019',
report_qtr: '4'
},
{
report_yr: '2017',
report_qtr: '2'
},
{ report_yr: '2008',
report_qtr: '2'
}];
//预期输出:
[
{ report_yr: '2019',
report_qtr: '4' },
{ report_yr: '2019',
report_qtr: '3' },
{ report_yr: '2008',
report_qtr: '1'
},{ report_yr: '2008',
report_qtr: '2'
},
{ report_yr: '2017',
report_qtr: '2' } ];
//我正在尝试:
我正在尝试为此使用loadash方法,
_.sortBy(arr,
['report_yr', 'report_qtr']);
同样尝试了orderBy,但到目前为止还没有运气。
最佳答案
您可以使用sort
方法,并使用简单的javascript做到这一点。
let arr = [{"report_yr":"2008","report_qtr":"1"},{"report_yr":"2019","report_qtr":"3"},{"report_yr":"2019","report_qtr":"4"},{"report_yr":"2017","report_qtr":"2"},{"report_yr":"2008","report_qtr":"2"}]
arr.sort((a, b) => b.report_yr - a.report_yr || b.report_qtr - a.report_qtr)
console.log(arr)
