Items API Initialization
errorListener()
This function is called when one of the preset Learnosity API errors are thrown.
You would want to define this callback so that you can display your own error message or track the error in your own error reporting systems, for example.
Examples
var callbacks = {
errorListener: function (errorEvent) {
console.log('The callback that is executed when a Learnosity API error occurs.');
console.log(errorEvent);
/* For example, providing an invalid Item reference will throw:
{
"code": 20013,
"msg": "Requested items could not be retrieved. Items references: missing_item_reference"
}
*/
},
// ...
};
var itemsApp = window.LearnosityItems.init(
initializationOptions,
callbacks
);
