JQuery.ajaxTransport (dataType, handler (options, originalOptions, jqXHR))

Description: create an object that handles the actual transfer of Ajax data.

DataType

Type: String

A string that identifies the data type used

Handler (options, originalOptions, jqXHR)

Type: Function ()

A handler that returns a new transport object using the data type provided in the first parameter.

Transport is an object that provides two methods, send and abort, which are internally used to make requests by $.ajax (). Transport is the most advanced method to enhance $. Ajax () and should only be used as a last resort when pre-filters (prefilters) and converters (converters) cannot meet your needs.

Since each request needs its own instance of a transport object, the transport cannot be registered directly. Therefore, you should provide a function instead of return transfer (transport).

The transports factory registration uses $.ajaxTransport (). A typical registration looks like this:

$.ajaxTransport (function (options, originalOptions, jqXHR) {

If (/ * transportCanHandleRequest * /) {

Return {

Send: function (headers, completeCallback) {

/ * send code * /

}

Abort: function () {

/ * abort code * /

}

}

}

})
