Here is a working function:

function allIndexOf(str, toSearch) {
    var indices = [];
    for(var pos = str.indexOf(toSearch); pos !== -1; pos = str.indexOf(toSearch, pos + 1)) {
        indices.push(pos);
    }
    return indices;
}

Use example:

> allIndexOf('dsf dsf kfvkjvcxk dsf', 'dsf');
[0, 4, 18]
