Question

Am I doing something wrong, or is it Google Chromes fault ?
Using non-capture and capture groups has the same effect as without them.

RegExr shows the first expected result. http://regexr.com?30mjo

var text = 'startdate: 123456, enddate: 789012';
var unix = text.match(/(?:start|end)date: (\d+)/g);
console.log(unix);

Actual result

["startdate: 123456", "enddate: 789012"]

Expected result

["123456", "789012"] or  
["startdate: 123456", "123456", "enddate: 789012", "789012"]

Answer 1

Looks like the spec says that it should work this way.

Relevant line is

4. Let matchStr be the result of calling the [[Get]] internal method of result with
argument "0"

on page 146 of the ecmascript spec where result is the array you get back from calling exec.

I’ve been unable to find a way to make this work, other than manually calling exec and collecting the results like so:

var regex = /(?:start|end)date: (\d+)/g;
var text = 'startdate: 123456, enddate: 789012';

var result;
var unix = [];

while(result = regex.exec(text)){    
    unix.push(result[1]);
}

console.log(unix);
