.split() 在空格和引号处，保留引号 - Regex/Javascript

Question

I would like to return an array from a string. The array should contain all characters as separate elements, except for spaces. My current regex looks like this:

str = 'Stuff in "quotation marks"';
arr = str.split(/(?=["])|[\s+]/);
console.log(arr);
// [ 'Stuff', 'in', '"quotation', 'marks', '"' ]

I would like it to return something like this:

// [ 'Stuff', 'in', '"', 'quotation', 'marks', '"' ]

What regex can I use to return the " in front of '"quotation' as a separate element in the array?

Answer 1

You could use String.prototype.match() ^_MDN

 const str = 'Stuff in "quotation marks"'; const arr = str.match(/\\w+|"/g); console.log(arr);

PS: Beware that \\w is analogous for [a-zA-Z0-9_]

---

You can also .split(/\\b/) at word boundaries /\\b/ but than trim and filter out empty values from the array:

 const str = 'Stuff in "quotation marks"'; const arr = str.split(/\\b/).map(w=>w.trim()).filter(w=>w); console.log(arr);

Disclaimer: the above examples will not work for special characters like š, ç, etc...
