This example shows how to get, set, and remove items from storage using the YUI SWFStore Utility and how to display stored data using a YUI DataTable.
Note that in cases where Flash is missing on the user's machine, the content of the Flash container does not get overwritten, and since the container is sized down to 0, additional logic (not demonstrated in this example) would be necessary to inform the user that no Flash is installed.
This example consists of two text fields, a few Buttons and a DataTable. The Buttons allow you to save data, set properties on SWFStore, or clear all items from storage.
Once the page is drawn, initialize
is called to instantiate a SWFStore instance and set up some listeners. We also disable all of the Buttons until the SWFStore is ready.
When SWFStore is ready, it will dispatch a contentReady
event. We can then enable the Buttons and initialize a DataTable with any previously stored values. Because items are stored as objects, we need to loop through them to turn them into name-value pairs suitable for use with the DataTable.
The "Save" Button is set up to take the values from the text fields and store them, using the setItem
method of SWFStore.
Similarly, a couple of other Buttons are set up to remove items from storage, either by name or index, or by clearing the entire local store.
We've already set up a listener for a "save" event, which is dispatched once an item is successfully stored. That calls the onSave
function, which loops through the rows of the DataTable. Using the info
property of the event, we can determine what type of change occurred, and either add rows, delete rows, or update its current values.
