Long ll_RootObject, ll_id
String ls_Json, ls_key, ls_name
boolean lb_active
lnv_JsonParser = Create JsonParser
ls_Json = '{"id":1001, "name":"evan", "active":true}'
// Loads a JSON string
lnv_JsonParser.LoadString(ls_Json)
ll_RootObject = lnv_JsonParser.GetRootItem()
// Gets the key of the child item
ls_key = lnv_JsonParser.GetChildKey(ll_RootObject, 1)
ll_id = lnv_JsonParser.GetItemNumber(ll_RootObject, ls_key)
ls_key = lnv_JsonParser.GetChildKey(ll_RootObject, 2)
ls_name = lnv_JsonParser.GetItemString(ll_RootObject, ls_key)
ls_key = lnv_JsonParser.GetChildKey(ll_RootObject, 3)
