Provides a simple interface for sending batch Ajax requests with jQuery. Simply include the jquery.batch.js file after jQuery in your development environment.

The standard usage of jQuery.Batch consists of simply running Ajax requests inside an anonymous function within the batch constructor and calling the send method, like so:

$.batch(function(){$.get('/users?order=name');$.post('/users/1',{name: 'Joe Strummer'});}).send();

Rather than sending the two requests individually, the data for each individual request would be serialized and sent as a single request to the server following the configuration settings described below.

Requests can also be added to a batch dynamically at any point by using the add method:

varbatch=$.batch();batch.add(function(){$.get('/users?order=name');});batch.send();

The send method itself can be passed a hash of options which are passed on to the $.ajax request for the entire batch. You could set a success callback to be handled upon completion of the full request, like so:

batch.send({success: success});

In addition, jQuery.Batch will respect the beforeSend method of each individual request. If this function returns false, the request will not be added to the batch.

$.batch(function(){$.ajax({url: '/users?order=name',beforeSend: function(xhr,settings){if(window.CachedRequests[settings.url]){returnfalse;}}});}).send();

By default, jQuery.Batch requests are sent with the following jQuery Ajax options set:

• url: _bulk
• type: POST
• contentType: application/json
• processData: false
• dataType: text

All of these defaults (and any other jQuery Ajax options) can be changed using the $.batchSetup function, like so:

$.batchSetup({contentType: 'application/x-www-form-urlencoded',processData: true});

In addition, the following helper functions are also configurable using $.batchSetup:

This is used to serialize the data of a single request. request is a hash consisting of:

• method - the request method
• path - the url path
• query - a string of query parameters (if any were passed)
• headers - a hash containing the request headers
• body - the request body

By default, this simply returns the request hash unchanged.

This is used to serialize an array of all requests before it is sent as a batch Ajax request. requests is simply an array of all the individual requests in a batch. By default, this returns the requests array after passing it through JSON.stringify.

This is used to parse out the response from the server. This must return an array of request hashes, with each hash consisting of (at least):

• status - the response status code
• body - the body of the request response

By default, parse assumes the server returns the results line-delimited (each request on one line) with each request as escaped-JSON text with a JSON body (thus, doubly-escaped JSON).

Install Node.js. Make sure you've installed Grunt and Bower globally:

npm install grunt-cli -g npm install bower -g 

Then, install the development dependencies:

npm install 

Lint and run the tests with:

npm test
