软件简介

This tiny plugin provides a registry for different xhr implementations to co-
exist.
It requires jQuery 1.3/1.2.7 with its new feature, the ‘xhr’ ajax
setting.

If you want to provide a new implementation, you need to do this:

jQuery.xhr.register( 'my_xhr', function( settings ){ return new MyXhrImplementation( settings ); });

The argument settings is the settings object used by jQuery.ajax.

To use it, you do:

$.ajax({ url:'...', transport:'my_xhr', // ... });

The default implementation is used by default (unless it’s overriden with
ajaxSetup) and it’s called ‘xhr’.
