Add a "hook" to all AJAX requests on a page

🎣Hook into AJAX Requests: A Must-Know Technique!🎣

Are you caught up in the world of AJAX requests? 🌐✨ Don't worry, we've got your back! Today, we'll unveil the magic of adding a "hook" to all AJAX requests on your page, regardless of whether you're using jQuery or other third-party scripts. 🚀💪

The Quest for the AJAX Hook

So, you're wondering if it's possible to intercept AJAX requests and perform actions before they are sent or on events? 🤔 You've come to the right place, my friend! Let's dive into the intriguing world of AJAX hooks. 💫

The Challenge: AJAX Requests with Third-Party Scripts

Imagine a scenario where you have a web page with a bunch of third-party scripts. Some of these scripts might be using jQuery, while others may not. 😱 Now, the challenge is to add a universal hook that works seamlessly for all AJAX requests, regardless of the framework used. 🔄🌍

Solution 1: Hijack jQuery's AJAX

If your web page relies heavily on jQuery for AJAX functionality, you're in luck! jQuery provides a neat way to attach pre-filters to AJAX requests using the ajaxPrefilter method. 🎉🔌

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
  // Perform your desired action here!
});

By hooking into ajaxPrefilter, you can intercept and modify AJAX requests right before they are sent. It's that simple! 😎

Solution 2: Taming AJAX Without jQuery

What if your page has AJAX requests that don't rely on jQuery's $ajax function? Fear not, for there's still a way to conquer this challenge! 🦸‍♂️🌟

Enter the XMLHttpRequest object. It is the foundation of AJAX, and we can tap into its power to add our hooks. Here's how you can do it:

(function() {
  var originalXhrOpen = XMLHttpRequest.prototype.open;
  
  XMLHttpRequest.prototype.open = function() {
    // Perform your desired action here!
    
    // Call the original method
    originalXhrOpen.apply(this, arguments);
  };
})();

By overriding the open method of XMLHttpRequest, you can accomplish the same goal of intercepting and performing actions on AJAX requests. Isn't that amazing? 🙌🔥
