The code generated by RJS was usually loaded using Ajax, e.g. by using Ajax-enabled helper methods Ruby on Rails provides, such as the link_to_remote helper. It was replaced by jQuery as of Rails 3.1 [8] 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.
Ajax.Request returns the raw XML output from an AJAX call, while the Ajax.Updater will inject the return inside a specified DOM object. The Ajax.Request below finds the current values of two HTML form input elements, issues an HTTP POST request to the server with those element name/value pairs, and runs a custom function (called showResponse ...
Certain jQuery object methods retrieve specific values (instead of modifying a state). An example of this is the val() method, which returns the current value of a text input element. In these cases, a statement such as $('#user-email').val() cannot be used for chaining as the return value does not reference a jQuery object.
For example, maybe you have a bot that publishes certain data to a Wiki page regularly, and you want your script to read that data. Careful with ctype . Set it to raw for normal Wiki pages, and application/json for pages where a template editor or admin has set the Content Model to JSON.
Ajax offers several benefits that can significantly enhance web application performance and user experience. By reducing server traffic and improving speed, Ajax plays a crucial role in modern web development. One key advantage of Ajax is its capacity to render web applications without requiring data retrieval, resulting in reduced server traffic.
Ajax uses a combination of both client-side scripting and server-side requests. It is a web application development technique for dynamically interchanging content, and it sends requests to the server for data in order to do so. The server returns the requested data which is then processed by a client-side script.
ZK is a server side framework which emits HTML and thus does not depend on client side presence of Gecko making it portable to any browser. ZK takes ZUML (xul and xhtml) serverside pages as input and outputs dhtml for the browser.
In July 2005, George Jempty suggested an optional variable assignment be prepended to JSON. [19] [20] The original proposal for JSONP, where the padding is a callback function, appears to have been made by Bob Ippolito in December 2005 [21] and is now used by many Web 2.0 applications such as Dojo Toolkit and Google Web Toolkit.
