JSObjectHasPropertyForKey top-level property

bool Function(JSContextRef ctx, JSObjectRef object, JSValueRef propertyKey, Pointer<JSValueRef> exception) JSObjectHasPropertyForKey

Tests whether an object has a given property using a JSValueRef as the property key. This function is the same as performing "propertyKey in object" from JavaScript. ctx (JSContextRef) object (JSObjectRef) The JSObject to test. propertyKey (JSValueRef) A JSValueRef containing the property key to use when looking up the property. exception (JSValueRef*) A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception. @result (bool) true if the object has a property whose name matches propertyKey, otherwise false.
