Javascript使用markdown而不是将url转换为url数组

Question

我有下面的代码，我有一些带有markdown的url("a"one_answers"b"(，还有一些没有("c"one_answers"d"(，我必须确保将它们变成一个字符串url数组，如下所示。

我该如何提出一些建议？

let a = "a [this](https://upload.wikimedia.org/wikipedia/commons/thumb/7/7e/T._rex_infection.png/440px-T._rex_infection.png)!"
let b = "b [this](https://upload.wikimedia.org/wikipedia/commons/thumb/7/7e/T._rex_infection.png/440px-T._rex_infection.png)! - [this](https://upload.wikimedia.org/wikipedia/commons/thumb/a/a9/Mosasaurus-Skelett.jpg/440px-Mosasaurus-Skelett.jpg)"
let c = "https://upload.wikimedia.org/wikipedia/commons/thumb/7/7e/T._rex_infection.png/440px-T._rex_infection.png"
let d = ["https://upload.wikimedia.org/wikipedia/commons/thumb/7/7e/T._rex_infection.png/440px-T._rex_infection.png", "https://upload.wikimedia.org/wikipedia/commons/thumb/a/a9/Mosasaurus-Skelett.jpg/440px-Mosasaurus-Skelett.jpg"]
let e = "['https://upload.wikimedia.org/wikipedia/commons/thumb/c/c9/Tyrannosaurus_rex_Sue_at_FMNH.jpg/440px-Tyrannosaurus_rex_Sue_at_FMNH.jpg']"
let f = "['https://upload.wikimedia.org/wikipedia/commons/thumb/c/c9/Tyrannosaurus_rex_Sue_at_FMNH.jpg/440px-Tyrannosaurus_rex_Sue_at_FMNH.jpg','https://upload.wikimedia.org/wikipedia/commons/thumb/b/bc/Mosasaurus_beaugei_34.JPG/440px-Mosasaurus_beaugei_34.JPG']"

const url = (text, autoMatch = false) => {
if (!autoMatch) return [text].flat();
if (autoMatch) {
const match = text.match(/((.*))/);
console.log("*", match, ";")
if (match === null) return "";
return match[1] || "";
}
};
console.log(url(a, true))
console.log(url(b, true))
//console.log(url(c))
//console.log(url(d))

我认为它可以帮助您：

const getLinksFromString = (text) => text.match(/https[^ '")]*/gi);
const getLinks = (data) => {
switch (typeof data) {
case 'string':
return getLinksFromString(data);
case 'object':
const links = [];

for (text of data) {
links.push(...getLinksFromString(text));
}

return links;
}
}
const data = "b [this](https://upload.wikimedia.org/wikipedia/commons/thumb/7/7e/T._rex_infection.png/440px-T._rex_infection.png)! - [this](https://upload.wikimedia.org/wikipedia/commons/thumb/a/a9/Mosasaurus-Skelett.jpg/440px-Mosasaurus-Skelett.jpg)"
console.log(getLinks(data))
