我需要检查map函数中的条件,以在零之前添加一位数字值,这意味着00.00到09.30的剩余值是相同的。
当前,所有值都位于该值的前面。
代码:
export class SelectOverviewExample implements OnInit {
days=[];
times =[];
ngOnInit(){
[...this.days] = weekdays;
// [...this.times]=IntervalTime;
this.OnCall();
}
OnCall(){
var toInt = time => ((h,m) => h*2 + m/30)(...time.split(':').map(parseFloat)),
toTime = int => [Math.floor(int/2), int%2 ? '30' : '00'].join(':'),
range = (from, to) => Array(to-from+1).fill().map((_,i) => from + i),
eachHalfHour = (t1, t2) => range(...[t1, t2].map(toInt)).map(toTime);
let x=[];
[...x]= eachHalfHour('0:00','15:30');
[...this.times]=x.map(i=>'0'+i);
;}
}
答案 0 :(得分:2)
[...this.times]=x.map(i=>{
if ( condition ) {
i = '0'+i;
}
return i;
});
谢谢Alexander Staroselsky,我打错了文字。
