Get.Transaction Class
Represents a Get transaction, which may contain requests for one or more JS or CSS files.
This class should not be instantiated manually. Instances will be created and
returned as needed by Y.Get's css()
, js()
, and load()
methods.
Constructor
Get.Transaction
()
Item Index
Methods
abort
-
[msg="Aborted."]
Aborts this transaction.
This will cause the transaction's onFailure
callback to be called and
will prevent any new script and link nodes from being added to the document,
but any resources that have already been requested will continue loading
(there's no safe way to prevent this, unfortunately).
Parameters:
-
[msg="Aborted."]
String optionalOptional message to use in the
errors
array describing why the transaction was aborted.
execute
-
callback
Begins execting the transaction.
There's usually no reason to call this manually, since Get will call it automatically when other pending transactions have finished. If you really want to execute your transaction before Get does, you can, but be aware that this transaction's scripts may end up executing before the scripts in other pending transactions.
If the transaction is already executing, the specified callback (if any) will be queued and called after execution finishes. If the transaction has already finished, the callback will be called immediately (the transaction will not be executed again).
Parameters:
-
callback
FunctionCallback function to execute after all requests in the transaction are complete, or after the transaction is aborted.
purge
()
Manually purges any <script>
or <link>
nodes this transaction has
created.
Be careful when purging a transaction that contains CSS requests, since
removing <link>
nodes will also remove any styles they applied.
