Argument |
Description |
|---|---|
|
objectname |
The name of the JSONParser object whose child object item you want to obtain. |
|
ParentItemHandle |
A long whose value is the handle of the parent item of JsonObjectItem type. |
|
Key |
A string whose value is the key of the child item of JsonObjectItem type. |
Return value
Long.
Returns the handle value of the child item if it succeeds and -1 if an error occurs. If any argument's value is null, the method returns null.
Usage
If the item value is null, this function will throw an error, therefore, it is recommended that before executing this function, call GetItemType to check if the item value is null. See example 2 in GetItemArray.
Examples
This example gets the value of the "date_object" item:
JsonParser lnv_JsonParser
String ls_Json
DateTime ldt_datetime
Date ldate_date
Time lt_time
Long ll_RootObject, ll_date_object
lnv_JsonParser = Create JsonParser
ls_Json = '{"id":1001, "name":"evan", "date_object":{"datetime":7234930293, “date”: "2017-09-21", "time": "12:00:00"}}'
lnv_JsonParser.LoadString(ls_Json)
ll_RootObject = lnv_JsonParser.GetRootItem()
ll_date_object = lnv_JsonParser.GetItemObject(ll_RootObject, "date_object")
ldt_datetime = lnv_JsonParser.GetItemDateTime(ll_date_object , "datetime")
ldate_date = lnv_JsonParser.GetItemDate(ll_date_object , "date")
lt_time = lnv_JsonParser.GetItemTime(ll_date_object , "time")
