+ + + + + Class io + + + +

+ + + + + +
+ The io class is a utility that brokers HTTP requests through a simplified +interface. Specifically, it allows JavaScript to make HTTP requests to +a resource without a page reload. The underlying transport for making +same-domain requests is the XMLHttpRequest object. YUI.io can also use +Flash, if specified as a transport, for cross-domain requests. +
+ + +
+

+ _io

+
+ + private + static + + + _io + ( + + + uri + + + , + c + + + , + i + + + ) + + +
+ Method for requesting a transaction. _io() is implemented as +yui.io(). Each transaction may include a configuration object. Its +properties are: +method: HTTP method verb (e.g., GET or POST). If this property is not +not defined, the default value will be GET. +data: This is the name-value string that will be sent as the transaction +data. If the request is HTTP GET, the data become part of +querystring. If HTTP POST, the data are sent in the message body. +xdr: Defines the transport to be used for cross-domain requests. By +setting this property, the transaction will use the specified +transport instead of XMLHttpRequest. Currently, the only alternate +transport supported is Flash (e.g., { xdr: 'flash' }). +form: This is a defined object used to process HTML form as data. The +properties are: +{ +id: object, //HTML form object or id of HTML form +useDisabled: boolean, //Allow disabled HTML form field values +to be sent as part of the data. +} +on: This is a defined object used to create and handle specific +events during a transaction lifecycle. These events will fire in +addition to the global io events. The events are: +start - This event is fired when a request is sent to a resource. +complete - This event fires when the transaction is complete. +success - This event fires when the response status resolves to +HTTP 2xx. +failure - This event fires when the response status resolves to +HTTP 4xx, 5xx; and, for all transaction exceptions, +including aborted transactions and transaction timeouts. +end - This even is fired at the conclusion of the transaction +lifecycle, after a success or failure resolution. +The properties are: +{ +start: function(id, args){}, +complete: function(id, responseobject, args){}, +success: function(id, responseobject, args){}, +failure: function(id, responseobject, args){}, +end: function(id, args){} +} +Each property can reference a function or be written as an +inline function. +context: Object reference for an event handler when it is implemented +as a method of a base object. Defining "context" will preserve +the proper reference of "this" used in the event handler. +headers: This is a defined object of client headers, as many as. +desired for the transaction. These headers are sentThe object +pattern is: +{ +header: value +} +timeout: This value, defined as milliseconds, is a time threshold for the +transaction. When this threshold is reached, and the transaction's +Complete event has not yet fired, the transaction will be aborted. +arguments: Object, array, string, or number passed to all registered +event handlers. This value is available as the second +argument in the "start" and "abort" event handlers; and, it is +the third argument in the "complete", "success", and "failure" +event handlers. +
