Can You Dynamically Modify Meta-Tags with JavaScript?

Altering Meta-Tags Using JavaScript for Dynamic Content

Can JavaScript be leveraged to modify the meta-tags of a webpage, despite their placement within the HTML head element? This question arises from a need to update meta-tags in response to content changes loaded through AJAX.

To address this query, it is possible to use JavaScript to change the content of meta-tags, enabling the modification of key metadata such as page description and title in real-time. For instance, to dynamically update the meta-description, you can employ the following code snippet:

document.querySelector('meta[name="description"]').setAttribute("content", _desc);

By replacing "_desc" with the desired description, this script targets the meta-tag with the specified name attribute and updates its content attribute accordingly. This approach offers a dynamic way to adjust meta-tags based on the changing content of your web application.
