| Argument | Type | Description |
|---|---|---|
| set | Array or Recordset | The Array or Recordset to get the result from. |
| index | Integer | The position of the item in set to be returned. |
| default value | any type | Specify a default value to return instead of the item itself. PhixFlow also returns this value:
If not specified |
If index is not a valid entry the function will return _NULL.
You expect get element to work on a list/array. Ask for something outside the array. Andy error but he got null... there is nothing at position 4
If you provided a default value
This default value is also used in the case where you ask for element 1 of an object that isn't a list. If you provide a default value then that is returned otherwise it just returns the object itself
If you dont; provide a list in get element, it doesnt fall over if you only ask for index 1
If you provide not a list... index 1 returns the thing..... pretends it it is a list....pretends its a list of 1 object...
Examples
getElement(["Red", "Green", "Blue"], 2)
...
Returns _NULL, as there is no element at position 8. OR you will get the default value provided
getElement(["Red"], 1)
Returns Red, treating it as if it is the first element in an array
getElement(["Red"], 2)
Returns either _NULL or the default-value, because there is no eleme
getElement ([1,2,3],4)
getElement ([1,2,3],0)
but currently just return null.
[].1
Returns _NULL.
