A pointer to the IDispatch type, the array object is actually a JavaScript built-in array object, and on the JavaScript side we can get the size of the array by the length property, so here You can get the length of an array through the GetIDsOfNames function and the Invoke function, which allows you to dynamically variable array contents.
