javascript - 哪些正则表达式可以替换所有其他单词？

给定以下句子：Crazy Fredrick bought many very exquisite opal jewels.，什么正则表达式可以让我过滤掉其他所有单词？我正在这样替换我：

"Crazy Fredrick bought many very exquisite opal jewels.".replace(/regex goes here/gi, "replace string goes here")

因此，我想创建一个正则表达式将其转换为Fredrick many exquisite jewels.或crazy bought very opal。

最佳答案

可以使用以下内容（假设您的单词都用\ w匹配）

"Crazy Fredrick bought many very exquisite opal jewels.".replace(/(\w+) (\w+)/g, '$1');
-> "Crazy bought very opal."

用$ 2替换$ 1可得到：

"Fredrick many exquisite jewels."
