Setting Transaction Timeouts with Connection Manager

The following code example provides a step-by-step approach to presetting a transaction timeout.

Source file and dependencies

Load the Yahoo Global Object and Connection Manager source files:

The Callback Object

The callback object includes a timeout property that allows you to specify the amount of time you're willing to wait for a transaction to complete before aborting. To cause a transaction to automatically timeout, the timeout property must be defined wih a value in millseconds. This example defines timeout with a value of 5000(milliseconds). If the transaction is not complete within 5000ms, it will be aborted.

Initiate the Transaction

Call YAHOO.util.Connect.asyncRequest to send the request to sync.php. The PHP script will return a string message after a random delay of 0 to 10 seconds if the transaction was not aborted. If the transaction was successfully aborted, the response object's status property will report -1 and the statusText property will report "transaction aborted".
