我怎样才能使这个 javascript 代码更简洁有没有办法对它们进行分组？

Question

所以我有这个三元运算符列表有没有办法让它更简洁？

var modalURL = window.location.hash;
modalURL == "#link-1" ? (linkID = "link-1") + showModal(linkID) : null;
modalURL == "#link-2" ? (linkID = "link-2") + showModal(linkID) : null;
modalURL == "#link-3" ? (linkID = "link-3") + showModal(linkID) : null;
modalURL == "#link-4" ? (linkID = "link-4") + showModal(linkID) : null;
modalURL == "#link-5" ? (linkID = "link-5") + showModal(linkID) : null;

我正在努力使它更简洁

Answer 1

最简洁的只是一个 function

const showModal = _ => {
  let linkID = window.location.hash.slice(1);

  if (linkID) {
    // do things with the id
  } 
}

Answer 2

您可以尝试使用动态循环：

    var modalURL = window.location.hash;
    for (var i = 1; i <= 5; i++) {
      if (modalURL === `#link-${i}`) {
        linkID = `link-${i}`;
        showModal(linkID);
        return;
      }
    }
