Is there a way to identify when the class of an HTML element is modified?

<div class="current"></div>
<a href="#">text</a>

Is there a way to detect when the .live class is added to this specific <div> and trigger an action as a result?

For instance, if the class changes, then automatically hide the link associated with it.

I am dealing with a condensed script that modifies the class of the <div>, but locating where in the codebase these changes are made has proven difficult. As a result, I am exploring methods to capture and respond to any class modifications.

Answer №1

Although there are DOM events, they are not perfect and may not be supported in all browsers. In simple terms: It's not a reliable option. Some workarounds include using intervals and checking continuously, but if you find yourself needing to resort to these methods, it may be a sign that your design needs reevaluation. It's important to realize that such approaches can slow down the application and introduce delays. The shorter the delay, the slower the performance. Avoid going down that path.

Answer №2

If you're looking for inspiration, take a look at this insightful article.

Answer №3

It's uncertain if the class you apply to the link remains constant, but if it does, have you considered leveraging CSS for this purpose?

<style type='text/css>
  .myaddedclass{display:none}
</style>

Answer №4

If you're looking to quickly understand the process (without writing code), Google Chrome's web inspector allows you to view real-time DOM modifications. However, it may not be applicable to your specific situation.
