问题描述
我有一些词，例如浅紫色"和深红色"，分别存储为浅紫色"和深红色".如何检查单词"LightPurple"中的大写字母，并在单词"Light"和"Purple"之间放置一个空格以形成单词"Light Purple".
I have some words like "Light Purple" and "Dark Red" which are stored as "LightPurple" and "DarkRed". How do I check for the uppercase letters in the word like "LightPurple" and put a space in between the words "Light" and "Purple" to form the word "Light Purple".
提前感谢您的帮助
推荐答案
您可以使用正则表达式在大写字母旁边的小写字母处添加空格.
You can use a regex to add a space wherever there is a lowercase letter next to an uppercase one.
类似这样的东西:
"LightPurple".replace(/([a-z])([A-Z])/, '$1 $2')
更新:如果您有2个以上的单词，则需要使用 g 标志将其全部匹配.
UPDATE: If you have more than 2 words, then you'll need to use the g flag, to match them all.
"LightPurpleCar".replace(/([a-z])([A-Z])/g, '$1 $2')
更新2 :如果试图拆分 CSVFile 之类的单词，则可能需要使用此正则表达式:
UPDATE 2: If are trying to split words like CSVFile, then you might need to use this regex instead:
"CSVFilesAreCool".replace(/([a-zA-Z])([A-Z])([a-z])/g, '$1 $2$3')
