从特定单词后面的字符串中获取数字

  • 772

从这些链接的 href 属性中，我需要获取数字 127885836、223388436 和 852485236。我该怎么做？这些数字可能不同，但它们始终位于“goods/”一词之后和破折号之前。

<div class="item">
  <a href="https://www.test.org/goods/127885836-truba_vodostochnaya_d150kh2000" class="link">Link</a>
</div>
<div class="item">
  <a href="https://www.test.org/goods/223388436-truba_vodostochnaya_d350kh1001" class="link">Link</a>

<div class="item">

    这些只是数组和字符串方法。普通的也可以，但是不知道怎么用

    const links = document.querySelectorAll('a')

const arr = Array.from(links)
.reduce((acc, link) => {
    const href = link.href

    let result = href.split('goods/')
    result = result[1].split('-')
    result = result[0]

    acc.push(result)
    return acc
}, [])

console.log(arr)
    <div class="item">
  <a href="https://www.test.org/goods/127885836-truba_vodostochnaya_d150kh2000" class="link">Link</a>

    这也是您可以...

    const arr = []
document.querySelectorAll('a').forEach(o => arr.push(o.href.match(/\d+/)[0]))

console.log(arr)
    <div class="item">
  <a href="https://www.test.org/goods/127885836-truba_vodostochnaya_d150kh2000" class="link">Link</a>
