One scenario could be when I receive this specific code from a third-party source
<a class="cs_import">Add contacts from your Address Book</a>
Curiously, the link "Add contacts from your Address Book" does not redirect to any page as expected. This raises the question of how it can be a link in the first place and what factors might cause it to malfunction?
Absolutely! It can be done.
It might be used as a fragment anchor. This doesn't apply in your scenario since there is no name attribute. However, if it had a name="myfragment" and the page file was named page.html, then page.html#fragment would automatically scroll the browser to that specific point on the page.
It could be purely for styling purposes. While this is a possible reason, it's not the most efficient way as styling can be achieved differently.
The href attribute might be assigned programmatically with JavaScript. For instance, a script could target all a tags with a specific class and assign an href based on the text value, like
$("a.cs_import").attr("href",getHref(this.text()));getHref(innerText) is a JavaScript function that retrieves the URL from the description text. There are usually better alternatives, but certain situations may call for this approach.Using JavaScript can make it achievable. By implementing a script that triggers upon page load, one can search for the specific element and assign an onClick event to it.
When it comes to enhancing links with javascript code, ensure that the third party has provided you with the necessary javascript file for inclusion. Double-check that you are adding this file in the correct location as per the vendor's guidelines.
href is an essential attribute of the link tag that should not be omitted for semantic and validation reasons. Some browsers may still display the element without it, but clicking on it might not work as expected.
In your situation, the link could potentially be improved with JavaScript at a later stage. Without this enhancement, it essentially functions as a glorified span element.
When an '<a>' element lacks a href attribute, it becomes non-focusable and is excluded from the tab order for keyboard navigation. Using href='#element' will add the hash to the current URL, while '#' without an anchor identifier functions as an id that does not exist on the page, often resulting in scrolling to the top of the page unless intercepted and managed.
