Javascript "Silly Name Generator"

我上个学期上了一门JavaScript课，通过了，现在我在放暑假。我们使用的是JavaScript第八版，Tom Negrino，多丽史密斯。这里有一个名称生成器的代码。所有需要的东西都在书里(第301页)它要求有姓和名，但我想加上一个中间名输出另一个愚蠢的名字。这不是家庭作业，只是别的我想试试。如果你把名字或姓留空，你会得到一个"That’s"不是有效的名称"消息。所以我编码了中间名，输入了26个单词中间名，但代码只识别第一名还有姓。对我来说，这看起来应该是可行的，但仍然只是第一步姓氏也有用。也许另一双眼睛能帮我看清什么我错过了或没有包括。

谢谢你的建议，CK
