This time I will introduce to you how to add ellipses when the text exceeds the specified number of lines, and what are the precautions for adding ellipsis when the text exceeds the specified number of lines. The following is a practical case, let's take a look.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>jQuery自动添加省略号</title>
  <script src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
  <script type="text/javascript">
    $(function () {
      $(".figcaption").each(function (i) {
        var pH = $(this).height();
        var $p = $("p", $(this)).eq(0);
        while ($p.outerHeight() > pH) {
          $p.text($p.text().replace(/(\s)*([a-zA-Z0-9]+|\W)(\.\.\.)?$/, "..."));
        };
      });
    });
  </script>
  <style>
    *{
      padding: 0px;
      margin: 0px;
    }
    .figcaption{
      width: 300px;
      height: 50px;
      /*根据父元素的高度来添加省略号
      *可以任意设置显示的行数
      */
      border: 1px solid red;
    }
  </style>
</head>
<body>
  <p class="figcaption">
    <p>
      You probably can't do it (currently?) without a fixed-width font like Courier. With
      a fixed-width font every letter occupies the same horizontal space, so you could
      probably count the letters and multiply the result with the current font size in
      ems or exs. Then you would just have to test how many letters fit on one line, and
      then break it up.</p>
  </p>
</body>
<script>
</script>
</html>
