When working with Asynchronous JavaScript, it is common to encounter issues where we are unsure of the posted request and received response.
Is there a simple method for debugging AJAX requests?
To easily view the request and response, follow these steps:
If you want to track each request, it is recommended to create a new object for every call:
let xhr;
xhr = new XMLHttpRequest();
xhr.id = (new Date()).getTime(); /* This is just an example and may not work if requests are made more than once per millisecond */
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && (xhr.status == 200)) {
// Perform your desired actions here
console.log(this.id);
}
}
