Connection Manager GET Transaction
To create a GET transaction using <a href="http://developer.yahoo.ru/yui/connection/">Connection Manager</a>, you will need to construct a querystring of key-value pairs and append it to the URL. The following code example provides a step-by-step approach to creating a simple GET transaction.
Click "Send a GET Request" below to try it out, then read the description below to learn how to create a simple transaction using Connection Manager.

} var handleFailure = function(o){
YAHOO.log("The failure handler was called. tId: " + o.tId + ".", "info", "example");
if(o.responseText !== undefined){
div.innerHTML = "- Transaction id: " + o.tId + " "; div.innerHTML += "

<a href="http://developer.yahoo.ru/yui/connection/">Connection Manager</a>"s built-in transaction timeout functionality.

Subscribing to Connection Manager Global Events
<a href="http://developer.yahoo.ru/yui/connection/">Connection Manager</a> exposes <a href="http://developer.yahoo.ru/yui/event/#customevent">Custom Events</a> that track the progress of a transaction through its lifecycle. These Custom Events are raised at the global level and at the transaction level. The following code example provides a step-by-step approach to subscribing to global custom events raised by Connection Manager. In this scenario, an event handler object is created to handle all Custom Events. Each Custom Event is explicitly subscribed with a reference to it"s event handler.
