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?

If you only want to find simple characters, or character sequences, you can use indexOf [MDN]:

var haystack = "abcdab",
    needle = "a"
    index = -1,
    result = [];

while((index = haystack.indexOf(needle, index + 1)) > -1) {
    result.push(index);
}
