Description
Gets the value of the item whose type is date.
Applies to
Syntax
objectname.GetItemDate ( ItemHandle )
|
Argument |
Description |
|---|---|
|
objectname |
The name of the JSONParser object whose item value you want to obtain. |
|
ItemHandle |
A long whose value is the item handle of JsonStringItem type. |
Return value
Date.
Returns the date value of the item if it succeeds; if any argument's value is null, returns null; if an error occurs, the SystemError event will be triggered.
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 second item according to the item handle:
JsonParser lnv_JsonParser
String ls_Json
Date ldate_date
Long ll_RootObject, ll_item
lnv_JsonParser = Create JsonParser
ls_Json = '{"datetime":7234930293, "date": "2017-09-21", "time": "12:00:00"}'
lnv_JsonParser.LoadString(ls_Json)
ll_RootObject = lnv_JsonParser.GetRootItem()
ll_item = lnv_JsonParser.GetChildItem(ll_RootObject, 2)
ldate_date = lnv_JsonParser.GetItemDate(ll_item)

Applies to
Syntax
objectname.GetItemDate ( ParentItemHandle, Key )
|
Argument |
Description |
|---|---|
|
objectname |
The name of the JSONParser object whose child item value 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 JsonStringItem type. |
Return value
Date.
Returns the date value of the child item if it succeeds; if any argument's value is null, returns null; if an error occurs, the SystemError event will be triggered.
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" item according to the parent item handle and the key name:
JsonParser lnv_JsonParser
String ls_Json
Date ldate_date
Long ll_RootObject
lnv_JsonParser = Create JsonParser
ls_Json = '{"datetime":7234930293, "date": "2017-09-21", "time": "12:00:00"}'
lnv_JsonParser.LoadString(ls_Json)
ll_RootObject = lnv_JsonParser.GetRootItem()
ldate_date = lnv_JsonParser.GetItemDate(ll_RootObject, "date")

|
Argument |
Description |
|---|---|
|
objectname |
The name of the JSONParser object whose item value you want to obtain. |
|
ItemPath |
A string whose value is the path of the item of JsonStringItem 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 "/". |

Examples
This example gets the value of the second item according to the item path:
JsonParser lnv_JsonParser
String ls_Json, ls_Path
Date ldate_date
lnv_JsonParser = Create JsonParser
ls_Json = '{"datetime":7234930293, "date": "2017-09-21", "time": "12:00:00"}'
lnv_JsonParser.LoadString(ls_Json)
ls_Path = "/date"
ldate_date = lnv_JsonParser.GetItemDate(ls_Path)
