在 laravel 刀片中的 foreach 循环上使用 javascript function

Question

I want to use javascript for word limit on <p> tags, using foreach loop. It works pretty well but only works on the first data, like this:

This is how my foreach seems like:

<?php foreach ($khotbah as $key): ?>
  <article class="article-post mb70">
    <div class="post-content">
      <a href="#"><h2 class="post-title">{{$key->title}}</h2></a>
      <ul class="post-meta list-inline">
        <li class="list-inline-item">
          <i class="fa fa-user-circle-o"></i> <a href="#">{{$key->author}}</a>
        </li>
        <li class="list-inline-item">
          <i class="fa fa-calendar-o"></i> <a href="#"><?php $date_created = date_create($key->created_at); echo date_format($date_created,'d F Y H:i')?></a>
        </li>
      </ul>
      <p>{{$key->description}}</p>

      <a href="ringkasan-khotbah/{{$key->id}}" class="btn btn-outline-secondary">Read More</a>
    </div>
  </article><!--article-->
<?php endforeach; ?>

and this is what I'm doing in my javascript:

<script type="text/javascript">
  function truncateText(selector, maxLength) {
    var element = document.querySelector(selector),
        truncated = element.innerText;

    if (truncated.length > maxLength) {
        truncated = truncated.substr(0,maxLength) + '...';
    }
    return truncated;
  }

  document.querySelector('p').innerText = truncateText('p', 107);
</script>

is it possible to use javascript on foreach loop? Should I put another method on my javascript so it can be used on foreach loop?

You need to select all of your paragraphs and apply your truncate to each.

I have commented in the code below:

 function truncateText(el, maxLength) { // no need to querySelector here now, // as we have passed in the element let truncated = el.innerText; if (truncated.length > maxLength) { truncated = truncated.substr(0, maxLength) + '...'; } return truncated; } // Run your truncate function when tyhe DOM has loaded document.addEventListener('DOMContentLoaded', (event) => { // select all your P's using querySelectorAll const ps = document.querySelectorAll('p'); // for each p, run your turncate function, passing the *element* ps.forEach((p) => {p.innerText = truncateText(p, 50);}); });
