In terms of saving memory and references use
jsonParent.length = 0

Nothing hacky =) it's javascript
If there are no other references to the same array then the easiest thing to do is just assign jsonParent to a new empty array:
jsonParent = [];
But if your code has other references to the same array instance then that would leave those other references with the original (populated) array and jsonParent with a different (empty) array. So if that is possible in your situation and you want to empty the actual array instance that you already have you can do:
jsonParent.length = 0;
// or if you like ugly:
jsonParent.splice(0, jsonParent.length);
(Note also that you are not using JSON here in any way. It's not JSON if it's not a string.)

just assign
jsonParent = []
again when you want to remove all elements
