按日期排序在边缘不起作用

Question

I am trying to sort a array object by date

this.result.sort((a, b) => {
if (this.filter.orderBy === 'possession') {
  //if(moment(a.overview.possession_starts).isAfter(moment(b.overview.possession_starts))) 
  //sort string ascending
  if (moment(a.overview.possession_starts) > moment(b.overview.possession_starts)) 
     //sort string ascending
     return 1;
  return 0;
});

is working fine in Mozilla and chrome

Answer 1

Your callback returns 1 , 0 or undefined . This isn't what's required by the sort function . Fix it:

if (this.filter.orderBy === 'possession') {
    this.result.sort((a, b) => {
           return moment(a.overview.possession_starts).milliseconds() - moment(b.overview.possession_starts).milliseconds();
    });
}

Answer 2

您可以用这一行替换您的代码。

this.filter.orderBy === 'possession' && this.result.sort((a, b) => moment(a.overview.possession_starts).milliseconds() - moment(b.overview.possession_starts).milliseconds());
