Syntax
| Code Block |
|---|
Result = SRP_JSONJson(Handle, "GETGet", Path) |
Returns
A valid JSON Entity Handle if the descendant was found, 0 if not.
Parameters
| Parameter | Description |
|---|---|
| Handle | Handle to a JSON Entity. Required. |
| Path | A formatted string indicating the desired descendant. Required. |
Remarks
The GET Get service returns a JSON Entity Handle to a descendant entity somewhere within the current JSON Entity Handle. Handle must point to a JSON object or JSON array for this method to work. Otherwise, it just returns the entity's current value.

| Code Block |

MenuHandle = SRP_JSONJson(ObjectHandle, "GETGet", "menu") |
If you want to get a child of menu (without having to get the menu handle first), you separate each member name with a period, like so:
| Code Block |
|---|
ItemsHandle = SRP_JSONJson(ObjectHandle, "GETGet", "menu.items") |
If you want to get an element within an array, you use square brackets instead of periods. This is how we drill down directly to the twelfth element within the items array:
| Code Block |
|---|
ItemHandle = SRP_JSONJson(ObjectHandle, "GETGet", "menu.items[12]") |
And this is how we get the handle to the "label" member of the second item in the items array:
| Code Block |
|---|
LabelHandle = SRP_JSONJson(ObjectHandle, "GETGet", "menu.items[2].label") |
| Note |
|---|
| This service always returns a JSON Entity Handle. If you know the descendant will be a String, Number, or Boolean type entity, you might prefer to use GETVALUEGetValue instead, which gets the value instead of the handle. |
