我的目標是讓這個函式只回傳“03.12.21, 16:12:52”。目前只回傳“]”。
let txt = `[03.12.21, 16:12:52] Firstname Lastname: Some text [03.12.21, 16:14:30] Firstname Lastname: Some text`;
console.log(parseDate()); // "]"
function parseDate() {
for (let i = 0; i < txt.length; i ) {
let char = txt[i];
let date = "";
date = char;
if (char === "]") {
return date;
}
}
}uj5u.com熱心網友回復：
let date = "";移出回圈（每次迭代都將其重置）
let txt = `[03.12.21, 16:12:52] First Name: Some text [03.12.21, 16:14:30] Felix Krückel: Some text`;
console.log(parseDate()); // "]"
function parseDate() {
let date = "";
for (let i = 0; i < txt.length; i ) {
let char = txt[i];
date = char;
if (char === "]") {
return date;
}
}
