Getting the Href from a collection of links

Question

使用基本的javascript，我可以找到所有感兴趣的a_hrefs。如何将对象列表转换为URL字符串列表？

document.querySelectorAll("a[href^='https://aaaa/']")

Answer 1

You can use Array.from , which takes an array-like object, and whose second parameter is an (optional) mapper function:

const urls = Array.from(
  document.querySelectorAll("a[href^='https://aaaa/']"),
  a => a.href
);
