按句点分割字符串，但如果句点后有空格则不分割

Question

I have a string like the following and want to split the names into an array using the period character as a separator. Some names unfortunately also contain the period character which is causing an incorrect split. I cannot modify the character being used to separate the names.

"John Smith.John Mc. Smith.Jim Smith"

Desired output

 ["John Smith","John Mc. Smith","Jim Smith"]

The following regex works well in the editor https://regex101.com/r/oK6iB8/32

But it does not work in the Chrome console

"John Smith.John Mc. Smith.Jim Smith".split('\.(?=\S)|:')

https://codepen.io/anon/pen/NogQrQ?editors=1111

Incorrect output

["John Smith.John Mc. Smith.Jim Smith"]

Why is this working in the Regex editor but not in the Codepen snippet ?

Answer 1

You can use this regex pattern.

\\.(?!\\s) - . should not be followed by space (negative lookahead)

 let str ="John Smith.John Mc. Smith.Jim Smith" let op = str.split(/\\.(?!\\s)/g) console.log(op) 

Why my code didn't worked

split('\\.(?=\\S)|:') because here you're giving \\.(?=\\S)|: as a string not as regular expression.

 console.log("John Smith.John Mc. Smith.Jim Smith".split(/\\.(?=\\S)|:/))
