How to Split a String by Commas While Ignoring Text Within Double Quotes in JavaScript?

Splitting Strings by Commas While Ignoring Text Within Double Quotes

The task of splitting a string by commas presents a unique challenge when commas appear within double quotes. Here's how to achieve this in Javascript:

<code class="js">var str = 'a, b, c, "d, e, f", g, h';
var arr = str.match(/(&quot;.*?&quot;|[^&quot;,\s]+)(?=\s*,|\s*$)/g);</code>

This regex-based approach follows a specific pattern to extract substrings:

• ("".*?" or [^",s] ): Matches either segments enclosed in double quotes ("d, e, f") or sequences without quotes, commas, or spaces (a).
• ((?=s*,|s*$)): Ensures matches are followed by either a comma and whitespace or the end of the string, ensuring proper splitting.

The result is an array of six elements:

arr = [ 'a', 'b', 'c', '"d, e, f"', 'g', 'h' ]
