可以做这样的事情：

$("a").each(function() {
     var linkName;
     linkName = this.href.replace("https://", "");
     linkName = linkName.replace(/-/g," ");
     linkName = linkName.replace(".com/", "");
     this.innerHTML = linkName;
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="map-container">
  <div class="map-pointer">
    <a href="https://my-link-1.com"></a>
  </div>
  <div class="map-pointer">
    <a href="https://my-link-2.com"></a>
  </div>
  <div class="map-pointer">
    <a href="https://my-link-3.com"></a>
  </div>
</div>

你可以试试这个：

let title = '';
$('.map-container a').map( function() {
    let href = $(this).attr('href');
    title = href.replace('https://', '').replace('.com', '').replaceAll('-', ' ');
    console.log(title)
    $(this).html(title);

}).get();
