JSObjectGetPropertyAtIndex(_:_:_:_:)

Declaration

func JSObjectGetPropertyAtIndex(_ ctx: JSContextRef!, _ object: JSObjectRef!, _ propertyIndex: UInt32, _ exception: UnsafeMutablePointer<JSValueRef?>!) -> JSValueRef!

Parameters

• ctx:

  The execution context to use.

• object:

  The Jsobjectref with the property you want to get.

• propertyIndex:

  An integer value that is the property’s name.

• exception:

  A pointer to a Jsvalueref to store an exception in, if any. Pass NULL to discard any exception.

Return Value

The property’s value, if object has the property; otherwise, the undefined value.

Discussion

Calling JSObjectGetPropertyAtIndex(_:_:_:_:) is equivalent to calling JSObjectGetProperty(_:_:_:_:) with a string that contains propertyIndex, but JSObjectGetPropertyAtIndex(_:_:_:_:) provides optimized access to numeric properties.
