How to split comma separated string using JavaScript?

Question

I want to split a comma separated string with JavaScript. How?

Does any of these any of these answers produce trimmed values? They're not. — N K, Oct 22 '13 at 07:46
@NK The OP didn't ask about trimming the values, though. Splitting on `','` is similar enough to splitting on `'~'` that it seems like this really is a duplicate. — Joshua Taylor, Oct 22 '13 at 14:44
@JoshuaTaylor, ideally splitting csv should produce a splitted and trimmed output — N K, Oct 23 '13 at 04:11
@NK I'm not aware of an authoritative standard for CSV which states this (but there might be such a thing; I'm just not aware of it), but even if there is, the OP didn't _ask_ for trimmed strings in the result. _As the question is phrased_, it's a duplicate of the other. If the requirement included trimmed spaces, then the OP always has the option to edit the question, at which point it might be reopened. Second-guessing the requirements and intent of a question-asker is useful sometimes, but sometimes its the path to unhelpful answers. — Joshua Taylor, Oct 23 '13 at 12:14
As the OP does not accept any of the given answers (every answers are same and similar to _original marked_ question), OP might not satisfy with the given answers or he didn't get a solution for his requirement. — N K, Oct 23 '13 at 12:31

@Andrew That's an entirely different question. Please read this one again. – alex Dec 10 '15 at 08:57
remove any garbage (") server-side before its presented to JS – Jonathan May 17 '16 at 09:17
& you can use `.join()` to put them back together again – Jack Dec 31 '18 at 20:44
@alex what if I have in str `{a: 'a'}` how can I stop the split function to split this object, and only work on a list of elements? – Tenzolinho Mar 25 '20 at 14:59
fails miserably when a field value contains a comma. obviously. – Marc Apr 12 '22 at 10:21

var result;
result = "1,2,3".split(","); 
console.log(result);

More info on W3Schools describing the String Split function.

Parse result like this `"val1 with extra, here",val2,val3` – Andrew Dec 09 '15 at 20:30
@Andrew The code will work perfectly to do that. If you want code to split on `,` and take into account quoted values, ask a new question :) – alex May 11 '18 at 15:00
