element.getPersistentData(name)
name A string that identifies the data to be returned.
The data specified by the name parameter, or 0 if the data doesn’t exist.
Method; retrieves the value of the data specified by the name parameter. The type of data depends on the type of the data that was stored (see element.setPersistentData()). Only symbols and bitmaps support persistent data.
The following example sets and gets data for the specified element, shows its value in the Output panel, and then removes the data:
// At least one symbol or bitmap is selected in the first layer, first frame.
var elt = fl.getDocumentDOM().getTimeline().layers[0].frames[0].elements[0];
elt.setPersistentData("myData","integer", 12);
if (elt.hasPersistentData("myData")){
fl.trace("myData = "+ elt.getPersistentData("myData")); elt.removePersistentData( "myData" );
fl.trace("myData = "+ elt.getPersistentData("myData"));
}
