hasNext( )

Indicates if there is a next item.

Description

Returns true if the current item is not the last item in the dataset.

Returns false if the current item is the last item in the dataset.

Calling hasNext() on a write-only dataset causes an error.

Note:
A dataset needs to load its data before you call its hasNext() function. Usually a dataset finishes loading a short time after the page it is on finishes loading. So if you call hasNext() inside the page’s onReady() event handler, the dataset might not be ready yet.
To call hasNext() as soon as possible after a page loads, use the dataset's onReady() function inside the page’s onReady() event handler to ensure that both the page and the dataset have finished loading.
