Description |
|---|---|
|
objectname |
The name of the JSONPackage object |
|
Key |
A string specifying the key of the item of JsonStringItem type. If more than one key with the same name already exists, the value of the first key will be obtained. |
Return value
Date. Returns the key value if it succeeds. If any argument's value is null, the method returns null. If an error occurs, throw the exception.
Examples
This example obtains the value of the birthday key from the JSON string, and converts the value from a string to a date.
The developer is recommended to check if the type of the key value is date before executing GetValueDate. If it is not a valid date-type value or it is a datetime-type value, the program will throw an exception.
// Date GetValueDate ( string Key )
Date ld_Birthday
JsonPackage ljpk_User
ljpk_User = Create JsonPackage
// Loads the JSON string to the JSONPackage object
ljpk_User.loadstring( '{"id":100,"name":"Henry.Ken","birthday":"1998-12-01 ","CreateDate":1543900359 }')
// Gets the value of the birthday key
ld_Birthday = ljpk_User.GetValueDate("birthday")
