How can I retrieve multiple indexes from multiple instances of a string search?

var str = "food";
var index1 = str.search("o"); // 1
var index2 = str.search("o"); // ?

Thanks much, Wen

I think the best way to do this for strings of non-trivial length is the RegExp.exec() function:

var str = "Foooooooood!",
    re = /o/g,
    match;
while (match = re.exec(str)) {
    console.log(match.index); // logs 1 through 9
}
