How to get all indexes of a pattern in a string?

Question

I want something like this:

\"abcdab\".search(/a/g) //return [0,4]

Is it possible?

Answer 1

You can get all match indexes like this:

var str = "abcdab";
var re = /a/g;
var matches;
var indexes = [];
while (matches = re.exec(str)) {
    indexes.push(matches.index);
}
// indexes here contains all the matching index values
