Jquery Ajax Cheat Sheet
What is AJAX
'AJAX an acronym for asynchronous JavaScript and XML is a group of interrelated web development techniques used on the client-side to create asynchronous web applications. With Ajax, web applications can send data to, and retrieve data from, a server asynchronously (in the background) without interfering with the display and behavior of the existing page. Data can be retrieved using the XMLHttpRequest object. Despite the name, the use of XML is not required (JSON is often used instead), and the requests do not need to be asynchronous.' - wikipedia
AJAX with jQuery
jQuery provides a $.ajax() method with a set of options for sending requests and callback methods to handle responses.
- Here is the most basic
$.ajax()request that does not send any data. It will be handled by thepost '/trips'route on the server. You can choose any of the http request verbs for the type parameter (get,post,put,delete)
Send data in a request
The $.ajax() Wolfenstein 3d for mac. method allows data to be sent in a request in a variety of formats. It also provides shorthand methods $.get() and $.post() which alias the $.ajax() method.
Form data
When using AJAX to post a form, you can also use the .serialize() method which creates a string of key : value pairs fromthe form data. You can also use the original action and method attributes from the form for the url and type parameters.
Register a callback function to verify the request
The $.ajax() method has three callback functions that are invoked on the response object. The.done() callback is invoked if the request is successful, the .fail() callback is invoked if therequest fails and the .always() is invoked regardless of success or failure. Start with a console.log()in the done and fail callbacks to make sure your AJAX is working.
Receive data from the server
ERB Partials
You can return a partial form from the server and then append it to the DOM using jQuery
JSON
Returning JSON data from the server allows flexibility on the client side as to how that data is displayed.
String data
You can also return basic string data from a request but JSON is generally more flexible as it allows multiple key:value pairs.
