javascript - 如何正确拆分 url，然后在 javascript 中获取剩余部分？

Question

我有一个来自 WordPress 的 json 对象中的 url 列表。我想用一个前缀来分割它们，我可以看到它是 https://www.example.co 然后获取其余部分，例如 /cat1/aa/bb/cc,/? page_id=8830，/xmlrpc.php

var myUrl = [
  {
    "URL": "https://www.example.co/cat1/aa/bb/cc",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat2/aa",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat1/aa/bb/cc/dd/ee",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat3/aa/bb/cc/",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat2/aa/bb",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat1/aa/bb",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/news/why-residents/attachment/san-francisco-blog/feed/",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/xmlrpc.php",
    "Last crawled": "Jun 19, 2019"
  },
  {
    "URL": "https://www.example.co/?page_id=8830",
    "Last crawled": "Jun 18, 2019"
  },
]

我当前的代码如下所示:

myUrl.forEach(function(item) {
    var urlList = item.URL.split("/");
    //console.log(urlList);
    console.log("https://www.example.co/" + urlList[3]);
});

上面的代码目前无法从前缀中获取剩余部分。

非常感谢任何帮助。谢谢

如果您只想从 URL 中删除域，则可以使用 String.prototype.replace 而不是 String.prototype.split。

例如:

const myUrl = [
  {
    "URL": "https://www.example.co/cat1/aa/bb/cc",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat2/aa",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat1/aa/bb/cc/dd/ee",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat3/aa/bb/cc/",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat2/aa/bb",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/cat1/aa/bb",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/news/why-residents/attachment/san-francisco-blog/feed/",
    "Last crawled": "Jun 23, 2019"
  },
  {
    "URL": "https://www.example.co/xmlrpc.php",
    "Last crawled": "Jun 19, 2019"
  },
  {
    "URL": "https://www.example.co/?page_id=8830",
    "Last crawled": "Jun 18, 2019"
  },
];

const paths = myUrl.map(value => value.URL.replace('https://www.example.co', ''));

console.log(paths);
