io Module
Defined in:
yui3/src/io/js/io-base.js:18
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. IO can also use Flash, if specified as a transport, for cross-domain requests.
Y.io('/some/url', {
on: {
success: function(id, e) {
Y.log(e.responseText);
}
}
});This module provides the following classes:
