What is jquery ajax URL?
Ajax is an innovation that permits engineers to make offbeat HTTP demands without the requirement for full-page revives. To make the cycle less bulky than it would be in unadulterated JavaScript, devs have been utilizing the jQuery library for quite a long time. In my article An Introduction to jQuery’s Shorthand Ajax Methods, I examined a portion of jQuery’s most-utilized Ajax shorthand techniques: $.get(), $.post(), and $.load(). They are helpful techniques for making Ajax demands in a couple of lines of code.
Once in a while, we need more power over the Ajax calls we need to make. For instance, we need to determine what ought to occur on the off chance that an Ajax call falls flat or we need to play out an Ajax demand yet its outcome is possibly required whenever recovered inside a specific measure of time.

In the next field, we have an ajax URL with an option as shown, this field is used to submit the specific format of JSON as per user requirement.
The URL boundary is a string containing the URL you need to reach with the Ajax call, while the indicated design is an item struct containing the arrangement for the Ajax demand.
In its first structure, this capacity plays out an Ajax demand utilizing the URL boundary and the choices determined in indicated design. In the subsequent structure, the URL is indicated in the predefined design boundary or can be overlooked, in which case the solicitation is made to the current page.
