How to stop an AJAX request using Chrome developer tools?

Is there a way to cancel an initiated ajax request from Chrome Developer Tools? I want to test if my fallback message displays correctly without changing the code. Setting No throttling to Offline will make all calls fail, but I just need one API to fail for debugging purposes.

I am aware of using the abort() method in JavaScript to cancel requests, but I prefer not to modify the code for this specific scenario.

In the right-click menu of the API, there is a replay XHR option. It would be helpful if there was also an abort XHR option available, but unfortunately there isn't.

Answer №1

One effective method I employ involves the combination of pressing F5, then ESC right after in the browser tab.

This action effectively cancels any ongoing XHR requests by Chrome, ensuring a smoother loading process for the new content.

Answer №2

Starting from Chrome 59, you have the ability to block specific requests directly from the Network tab in the developer tools.

Learn more about this feature here

To block a request, simply right-click on it in the Network panel and choose "Block Request URL". A new tab called Request blocking will appear in the Drawer, where you can manage the blocked requests.

In my situation, I will execute the code that blocks a particular API and then re-run it for testing purposes :)

This action does not immediately cancel any ongoing requests. It's more of an experiment to see how the application responds when only one request is intentionally failed. Thanks to @Ross Ivantsiv for pointing this out!
