如何提取任意对象的所有成员(方法,变量,常量,对象等)并将它们传递给块?
def inside(obj)
#pass all the members of the object to the block
end
inside myLink do
url = "myurl.com"
end
答案 0 :(得分:2)
您可以使用instance_eval:
def inside obj, &block
obj.instance_eval &block
end
你仍然需要使用自己:
inside myLink do
self.url = "myurl.com"
# or:
@url = "myurl.com"
end
