使用特定的前导和尾随字符拆分JavaScript字符

Question

I have a string which looks like this: "foo, bar,baz"

I need your help with regexp to split it on commas that are surrounded by anything on both sides, eg ['foo, bar', 'baz']

Answer 1

You may match all the substrings you need with /(?:\\s,\\S|\\S,\\s|[^,])+/g regex:

 var regex = /(?:\\s,\\S|\\S,\\s|[^,])+/g; var str = "foo, bar,baz"; console.log(str.match(regex)); 

See the regex demo

The regex matches 1+ occurrences of:

• \\s,\\S - a whitespace, , , non-whitespace
• | - or
• \\S,\\s - a non-whitespace, , , whitespace
• | - or - [^,] - a char other than ,
