新手來了！我想從今天開始回圈（例如：“星期四”），我想讓它在“星期三”停止......這可能嗎？任何幫助表示感謝！謝謝
let days = [
"Sunday",
"Monday",
"Tuesday",
"Wednesday",
"Thursday",
"Friday",
"Saturday",
];
let date = new Date();
let today = date.getDay();
let result = [];
for (let i = today; i < days.length; i ) {
result.push(days[i]);
}
return result[index];
};```
uj5u.com熱心網友回復：
為簡單起見，您可以從todayto回圈days.length，然后再從0to回圈today。
let days = [
"Sunday",
"Monday",
"Tuesday",
"Wednesday",
"Thursday",
"Friday",
"Saturday",
];
let date = new Date();
let today = date.getDay();
let result = [];
for (let i = today; i < days.length; i ) {
result.push(days[i]);
}
for (let i = 0; i < today; i ) {
result.push(days[i]);
}
console.log(result);轉載請註明出處，本文鏈接：https://www.uj5u.com/qiye/461079.html
