Description
Gets the string value of the item whose type is array.
Applies to
Syntax
objectname.GetItemArrayJSONString ( ParentItemHandle, Key )
|
Argument |
Description |
|---|---|
|
objectname |
The name of the JSONParser object whose array 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 JsonArrayItem type. |
Return value
String.
Returns the string value of the item if it succeeds and -1 if an error occurs. If any argument's value is null, the method returns null. If an error occurs, the method throws the exception.
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.
Example
The following code gets the JSON string of an array according to the key name:
JsonParser lnv_JsonParser
String ls_Json, ls_Array
Long ll_RootObject
lnv_JsonParser = Create JsonParser
ls_Json = '{"id":1001, "name":"evan", "department_array":[999999, {"name":"Website"}, {"name":"PowerBuilder"}, {"name":"IT"}] }'
lnv_JsonParser.LoadString(ls_Json)
ll_RootObject = lnv_JsonParser.GetRootItem()
ls_Array = lnv_JsonParser.GetItemArrayJSONString(ll_RootObject, "department_array")

Syntax
objectname.GetItemArrayJSONString ( ItemPath )
|
Argument |
Description |
|---|---|
|
objectname |
The name of the JSONParser object whose array item you want to obtain. |
|
ItemPath |
A string whose value is the path of the item of JsonArrayItem type. If there is a multi-dimensional array, use the number to indicate the order of the array elements. If a key name contains "/", use the escape character "~~/" to replace "/". |
Return value
String.
Returns the string value of the item if it succeeds and -1 if an error occurs. If any argument's value is null, the method returns null. If an error occurs, the method throws the exception.
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.
Example
The following code gets the JSON string of an array according to its item path:
JsonParser lnv_JsonParser
String ls_Json, ls_Array, ls_Path
lnv_JsonParser = Create JsonParser
ls_Json = '{"id":1001, "name":"evan", "department_array":[999999, {"name":"Website"}, {"name":"PowerBuilder"}, {"name":"IT"}] }'
lnv_JsonParser.LoadString(ls_Json)
ls_Path = "/department_array"
ls_Array = lnv_JsonParser.GetItemArrayJSONString(ls_Path)
