How can I get a regex to find every match in javascript? [duplicate]

Answer 1

This works with most pcre engines.
Capture 2, consume 1.

/(?=(\d\d))\d/g

var pat = /(?=(\d\d))\d/g;
var results = [];
var match;

while ((match = pat.exec('1234567')) != null) {
  results.push(match[1]);
}

console.log(results);

Output: 12,23,34,45,56,67
