In this article, we’ll look at how to match multiple occurrences with a regex in JavaScript similar to PHP’s preg_match_all().
How to match multiple occurrences with a regex in JavaScript similar to PHP’s preg_match_all()?
To match multiple occurrences with a regex in JavaScript similar to PHP’s preg_match_all(), we can use the string matchAll method.
For instance, we write
const regexp = /(?:&|&)?([^=]+)=([^&]+)/g;
const str = "1111342=Adam%20Franco&348572=Bob%20Jones";
for (const match of str.matchAll(regexp)) {
const [full, key, value] = match;
console.log(key, value);
}
to call str.matchAll to match the regex for a query string.
We use a for of loop to get all the matches.
In the loop, we get the full string match and the key and value of the query string from the match.
Conclusion
To match multiple occurrences with a regex in JavaScript similar to PHP’s preg_match_all(), we can use the string matchAll method.
