How to Convert Comma Separated String into an Array in JavaScript

Topic: JavaScript / jQueryPrev|Next

Answer: Use the split() Method

You can use the JavaScript split() method to split a string using a specific separator such as comma (,), space, etc. If separator is an empty string, the string is converted to an array of characters.

The following example demonstrates how to convert a comma separated string of person name into an array and retrieve the individual name using JavaScript.

  • <script>
  • var names = 'Harry,John,Clark,Peter,Rohn,Alice';
  • var nameArr = names.split(',');
  • console.log(nameArr);
  •  
  • // Accessing individual values
  • alert(nameArr[0]); // Outputs: Harry
  • alert(nameArr[1]); // Outputs: John
  • alert(nameArr[nameArr.length - 1]); // Outputs: Alice
  •  
  • var str = 'Hello World!';
  • var chars = str.split('');
  • console.log();
  •  
  • // Accessing individual values
  • alert(chars[0]); // Outputs: H
  • alert(chars[1]); // Outputs: e
  • alert(chars[chars.length - 1]); // Outputs: !
  • </script>
