Then the server receives the request, does the search and returns the data to the browser.In the background of this process, the browser creates an HTTP request for the server.

Through the browser, a call is generated in JS and later activates the XMLHttpRequest.( I stress that throughout this process the user can not do anything but wait for the results of their request to be loaded, this process, besides being tedious, ends up requiring a lot of resources from the server) Finally the browser, receiving the data, reloads the page showing the new information.After the search the server returns with the requested data.This server receives the request and searches the data.HTTP request is sent from the browser to the server.However, it is worth noting that the insert process with ajax becoming a bit slower,since too much information is preloaded, but in the end, only the data will need to be loaded, resulting in a site much more agile. When a user makes a request, the search and return is make in JS simultaneously, so it is not necessary to make “reload” the page all the time. In AJAX is a bit different, I say this why, in the process page loading, the entire load of processed data is passed to the client. To understand this, first we need understand as a common web application it’s work, what basically occurs is that the search engine will fetch information about the server and return to the client. In conception, using AJAX need to knowing JS well, work with, DOM, XML and CSS. A suite of technologies that enable a more productive and rich user interface. Hello, in this post we will conceptually understand the AJAX event and how use inside the Scriptcase.ĪJAX, is an acronym for Asynchronous JavaScript and XML, is a set of web development technologies that focuses on building more interactive applications, having as one of the main objectives a rapid response of web pages through the exchange of small information between the web server, besides to don’t need to the entire page is reloaded whenever a new action is performed.ĪJAX features, very broadly speaking, can be resume up in three words: usability, speed, and interactivity.
