Removed in ArduinoJson 6.20: use operator[] instead.


JsonArray::getElement() gets the value at the specified index in the array pointed by the JsonArray.

If the JsonArray is null/unbound, this function does nothing.

Instead of this function, you can use operator[] which offers a more intuitive syntax.


JsonVariant getElement(size_t index) const;


index: the index of the value in the array.

Return value

JsonArray::getElement() returns a JsonVariant that points to the value at the specified index.

JsonArray::getElement() returns null when the index is out of range; in which case JsonVariant::isNull(), returns true.
