What Is Ajax?

Ajax means Asynchronous JavaScript and XML. Ajax is not a programming language. Ajax is a technique for asynchronous information exchange using JavaScript and XML. Ajax lets you update only part of a web page without reloading the entire page. Ajax exchanges data with the server in the background and displays or loads data on the web page.

The following example loads data by using the .load() method provided by jQuery.

$("#btnLoad").on("click", function() {
  $("#text").load("/rest/1/pages/244");
});

Run code
