如何让文本在 jquery 中读取 more/less？

Question

我不知道也许 jquery 不工作。错误在哪里？我想在点击时减少阅读更多类型的文本。当我单击“阅读更多”时，没有任何反应。如何解决？

$('.moreless-button').click(function() {
  $('.moretext').slideToggle();
  if ($('.moreless-button').text() == "Read more") {
    $(this).text("Read less")
  } else {
    $(this).text("Read more")
  }
});

.moretext {
  display: none;
}

Answer 2

您需要在使用前参考 jQuery 文件。

这可以通过从 here 下载源文件并添加

来完成

<script src="jquery-3.x.x.min.js"></script>

或者更方便简单的方法是使用 CDN：

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
