Understanding the Issue with Anchor Links in iOS 8 Mail App: How to Create Accessible TOC Links and More

The recent release of iOS 8 has brought about a significant change for newsletter creators and email marketers. One of the most notable issues is the rendering of anchor links in newsletters on the iPhone mail app, which no longer supports them.

Anchor links have been a staple of web development for years, allowing users to navigate between different sections of a webpage. In HTML, these links are created using the <a> tag with an id attribute that refers to a specific element on the same page. For example:

<a id="top">Go to top</a>
<div id="content">
  <!-- content here -->
</div>

In this example, clicking on the “Go to top” link will take the user to the #top section of the webpage.

With the release of iOS 8, Apple made a change that affected how anchor links are handled in newsletters. The iPhone mail app no longer supports anchor links, which means they will not render correctly on devices running iOS 8 or later.

The issue is caused by the way iOS 8 handles <a> tags with href attributes that reference an id attribute of a specific element on the page. Instead of navigating to the corresponding section, the link will attempt to open a webpage at the specified URL, which is not what was intended.

The question raises an interesting point about how this affects Table of Contents (TOC) links in newsletters. TOC links are typically created using anchor links that reference specific sections within the newsletter. However, since iOS 8 no longer supports anchor links, these links will also fail to render correctly.

This can cause issues for users who try to access their newsletters on devices running iOS 8 or later. Instead of jumping to the relevant section, they may be taken to a webpage at the specified URL, which is not what they intended.

The Solution: Alternative Methods

So, how can newsletter creators and email marketers work around this issue? There are several alternative methods that can be used:

  1. Use relative URLs: Instead of using absolute URLs for anchor links, try using relative URLs. This will ensure that the link points to a specific section within the same document.
  2. Use JavaScript: You can use JavaScript to create anchor links that navigate to specific sections within the newsletter. This method requires some development expertise, but it provides a reliable solution.
  3. Use an image instead of a link: Another approach is to use an image instead of a link for TOC links. This will ensure that the user can still jump to the relevant section, even if anchor links are not supported.

Code Examples

Here’s an example of how you might create a relative URL anchor link:

<a href="#top">Go to top</a>

This link references the #top element on the same page. When clicked, it will navigate to that section.

For more complex newsletters, you may need to use JavaScript to create anchor links. Here’s an example using jQuery:

$('#toc-link').on('click', function() {
  var sectionId = $(this).data('section');
  $('#content').animate({
    scrollTop: $(sectionId).offset().top
  }, 500);
});

This code creates a link with the #toc-link ID, which references a specific section (#toc-content) on the same page. When clicked, it will animate the user to that section.

For TOC links, you can use an image instead of a link. Here’s an example:

<img src="image.jpg" alt="Go to top">

This creates an image with a “Go to top” caption. When clicked, it will navigate the user to the #top section on the same page.

Alternatively, you can use JavaScript to create TOC links. Here’s an example:

$('#toc-link').on('click', function() {
  var sectionId = $(this).data('section');
  $('#content').animate({
    scrollTop: $(sectionId).offset().top
  }, 500);
});

This code creates a link with the #toc-link ID, which references a specific section (#toc-content) on the same page. When clicked, it will animate the user to that section.

Conclusion

In conclusion, the recent release of iOS 8 has brought about an important change for newsletter creators and email marketers. While anchor links are still supported in most email clients, they no longer work in the iPhone mail app on devices running iOS 8 or later.

Fortunately, there are several alternative methods that can be used to create anchor links and TOC links in newsletters. By using relative URLs, JavaScript, or images, you can ensure that your newsletter remains accessible to users on devices with iOS 8 or later.

Remember, as developers, it’s essential to stay up-to-date with the latest technologies and platforms to provide the best experience for our users.
