Ajax is a technology that allows developers to make asynchronous HTTP requests without the need for a full page refresh. To make the process less cumbersome than it would be in pure JavaScript, devs have been using the jQuery library for years. They are convenient methods for making Ajax requests in a few lines of code. Sometimes, we need more control over the Ajax calls we want to make. For example, we want to specify what should happen in case an Ajax call fails or we need to perform an Ajax request but its result is only needed if retrieved within a certain amount of time. It was added to the library a long time ago, existing since version 1. The signatures of this function are shown below:. The url parameter is a string containing the URL you want to reach with the Ajax call, while settings is an object literal containing the configuration for the Ajax request. In its first form, this function performs an Ajax request using the url parameter and the options specified in settings.
