jQuery .data() implementation guide after AJAX call with dynamic content - behavior issues
I'm working through a tutorial and I'm not sure how to approach I tried several approaches but none seem to work. I'm experiencing an scenario where I update a jQuery data attribute using `.data()` after an AJAX call, but it seems that the updated value is not reflected when I try to read it later. Specifically, I'm using jQuery 3.6.0 and making an AJAX request to fetch user details that I want to store in a data attribute on a button element. Here's what I've tried so far: ```javascript // Making an AJAX call to fetch user data $.ajax({ url: '/api/user', method: 'GET', success: function(response) { // Assuming response is { id: 1, name: 'John Doe' } $('#myButton').data('userId', response.id); console.log($('#myButton').data('userId')); // Logs '1' }, behavior: function() { console.log('behavior fetching user data.'); } }); ``` After setting the data attribute, I try to read it later in a different function, but it returns `undefined`: ```javascript function getUserId() { console.log($('#myButton').data('userId')); // Logs 'undefined' } ``` I suspect that the context in which I am trying to access the data attribute might be causing the scenario, but I've checked and ensured that the button exists in the DOM when I'm trying to access it. I've also tried using `attr()` to set a custom attribute directly, but I need to use `.data()` for the intended data handling. Any insights on why the data might not be persisting as expected? Am I missing a crucial step in the lifecycle of the AJAX request or the jQuery data handling? Has anyone else encountered this? This issue appeared after updating to Javascript stable. This is part of a larger web app I'm building. Any suggestions would be helpful.
