如何用分号分隔逗号，分号和逗号分隔的短语？

Question

How to split comma, semicolon and comma separated phrases with semicolons around where it should treat anything between semicolons with a comma as the delimiter, but also delimit just comma and semicolon all together in funcion?

String of words:

var words = "apple;banana;apple, banana;fruit"

Regex function separate by , and ;

 var result = words.split(/[,;]+/);

Result from that function is:

[ "apple", "banana", "apple", " banana", "fruit" ]

But what I am looking to get is this, to have "banana, apple" and treat it as a separate value

[ "apple", "banana, apple", " banana", "fruit" ]

So is it possible to combine 2 cases in that function to output as the second example? Or maybe some other elegant way?

Answer 1

A combination of match and replace can be used.

With the match we take the two patterns we have

1. Values between delimiter (?:\\w+;\\w+,)
2. Value not in between delimiter \\w+;?

Now based on matched group we just change the values in desired format using replace

 let words = `apple;banana;apple, banana;fruit` let op = words.match(/(?:\\w+;\\w+,)|\\w+;?/g) .map(e=>e.replace(/(?:(\\w+);(\\w+),)|(\\w+);?/g, (m,g1,g2,g3)=> g1 ? g1+', '+g2 : g3 )) console.log(op) 

Answer 2

Array math is easier than regex.

Objective

apple;banana;apple, banana;fruit > [ "apple", "banana, apple", " banana", "fruit" ]

Remove spaces, split at ; , split at , .

Solution

 const words = 'apple;banana;apple, banana;fruit'; const result = words.split(' ').join('').split(';').join(',').split(','); console.log(result); 

Answer 3

Accorting to question apple-banana second example (after this question update) try

words.split(';');

 var words = "apple;banana;apple, banana;fruit" var result = words.split(';'); console.log(result);
