Guide to dynamically loading webpage content based on URL with JavaScript

During a recent interview, I was challenged to develop a code snippet that would highlight the URL if it contained a specific keyword. Admittedly, I am unsure how to achieve this using JavaScript...

Answer №1

In my opinion, the best way to handle this situation is by fetching content through ajax, searching for keywords, and then highlighting the necessary URLs. However, there are limitations to consider:

  1. The URL you want to highlight must allow cross-site ajax fetching.
  2. Performance may suffer if you have to fetch multiple URLs.
  3. If the targeted URL uses client-side rendering, simply fetching its HTML will not display the content as it has not been rendered yet.

Usually, the front-end approach is not sufficient in solving this problem; instead, using search engine indexing methods is more effective.
