检查您网页上生成的html，并根据其外观更改javascript代码。

例如，您可以制作2个链接（标记:)切换可见性，如下所示：

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<script type="text/javascript">
  $(document).ready(function() {
    //all <button>s on page that are clicked:
    $("button").click(function() {
      //Switch text on button.
      $(this).text($(this).text() == 'Follow' ? 'Unfollow' : 'Follow');

      //Select all links (tag <a>) on page.
      $('a').toggle(); //toggle display: none/initial (visibility)
    });
  });
</script>

<!-- links that are going to be switched visibility -->
<a href="/follow" style="display:none;">follow</a>
<a href="/unfollow">unfollow</a>

<!-- button that has the event listener click in javascript code above -->
<button type="button">Follow</button>
<p><strong>Note:</strong> Click the button to swap the text and the URL.</p>

＆＃13;

另一种选择是替换html标记中的href属性：

// select element - change attr - chose attribute (href in this case) - set new value
$('YourSelectorHere').attr('href','NewLinkHere');
