count variable substring inside a string in javascript

Question

i have a string in javascript like this:

var stringa = 'CONCATENATE("custom text 1", CHAR(10), "text", CHAR(10), "other text", CHAR(10), "another one", CHAR(10), "funny last string")';

My goal is to count the substring inside the string, splitted by ,, excluding CHAR(10). The constant rule is: substring I need to count are inside " " so in my example there are 5 substring.

How can I do it only using javascript or jquery?

I've found this solution but I think is there is a more elegant way:

var total = stringa.match(/\"/g) || []).length / 2;

You could split on `"` get length of returned array - 1 and divide by 2... — brso05, Dec 20 '19 at 14:28

@AnatoliiParubets i need only count occurrencies of a value inside " .. " — Giuseppe Lodi Rizzini, Dec 20 '19 at 14:33
"Elegance" is a very subjective measurement. One person's elegant is another's confusing unmaintainable spaghetti. — Heretic Monkey, Dec 20 '19 at 14:33

You could split on " get length of returned array - 1 and divide by 2...

var stringa = 'CONCATENATE("custom text 1", CHAR(10), "text", CHAR(10), "other text", CHAR(10), "another one", CHAR(10), "funny last string")';

var temp = stringa.split('"');
var count = (temp.length - 1) / 2;
window.alert(count);

You can use RegExp for that:

var stringa = 'CONCATENATE("custom text 1", CHAR(10), "text", CHAR(10), "other text", CHAR(10), "another one", CHAR(10), "funny last string")';

var matches = stringa.match(/"([^"]+)"/g) || [];
console.log(matches);
var count = matches.length;
console.log(count);

Oh, you've updated the question. Well, then I think there's nothing wrong with the regex approach – Sebastian Kaczmarek Dec 20 '19 at 14:37
