Use the split() method on the string and pass a comma as a parameter to split a string into an array by comma in JavaScript. This method divides the string on each comma and returns the substrings in an array.
var array = string.split(',');MDN reference, is mostly helpful for the possibly unexpected behavior of the limit parameter. (Hint: "a,b,c".split(",", 2) comes out to ["a", "b"], not ["a", "b,c"].)
JavaScript splits a string into arrays by comma
A simple example code converts a Comma Separated String to an Array.
<!DOCTYPE html>
<html>
<head>
<body>
<script>
var names = 'Harry,John,Clark,Peter,Rohn,Alice';
var nameArr = names.split(',');
console.log(nameArr);
// Accessing individual values
console.log(nameArr[0]); // Harry
console.log(nameArr[1]); // John
console.log(nameArr[nameArr.length - 1]); // Alice
var str = 'Hello World!';
var chars = str.split('');
console.log(chars);
// Accessing individual values
console.log(chars[0]); // H
console.log(chars[1]); // e
console.log(chars[chars.length - 1]); // !
</script>
</body>
</html>Output:
