Many of the Ruby on Rails Ajax-enabled helper methods used to work by using Prototype to perform an Ajax request in older versions of Rails. In most cases Javascript code is returned by the server to be executed by the browser, unlike the usual case where Ajax is used to retrieve data in XML or JSON format. [9]
JavaScript Object Notation (JSON) is often used as an alternative format for data interchange, [15] although other formats such as preformatted HTML or plain text can also be used. [16] A variety of popular JavaScript libraries, including JQuery, include abstractions to assist in executing Ajax requests.
Rather than listing an imperative sequence of actions to perform in a stateful environment, template rules only define how to handle a node matching a particular XPath-like pattern, if the processor should happen to encounter one, and the contents of the templates effectively comprise functional expressions that directly represent their ...
XMLHttpRequest (XHR) is an API in the form of a JavaScript object whose methods transmit HTTP requests from a web browser to a web server. [1] The methods allow a browser-based application to send requests to the server after page loading is complete, and receive information back. [2] XMLHttpRequest is a component of Ajax programming.
Asynchronous JavaScript and JSON (or AJAJ) refers to the same dynamic web page methodology as Ajax, but instead of XML, JSON is the data format. AJAJ is a web development technique that provides for the ability of a web page to request new data after it has loaded into the web browser. Typically, it renders new data from the server in response ...
At present, the ASP.NET AJAX suite consists of the following components and packages: Microsoft Now Launched Ajax Library 4.0, which supports Data Driven Web Applications. Microsoft Ajax Library 3.5, which is a JavaScript library that provides the client-side features of the ASP.NET AJAX framework.
The XMLHttpRequest (XHR) object, a tool used by Ajax applications for browser–server communication, can also be pressed into service for server–browser Comet messaging by generating a custom data format for an XHR response, and parsing out each event using browser-side JavaScript; relying only on the browser firing the onreadystatechange ...
It is one of the message exchange formats used in the Asynchronous JavaScript and XML (AJAX) programming technique. Many industry data standards, such as Health Level 7 , OpenTravel Alliance , FpML , MISMO , and National Information Exchange Model are based on XML and the rich features of the XML schema specification.
