How $_GET[‘updated’] variable is passed when updating a user?

I have found a javascript solution. Here is the code:

member.js (needs jQuery)

$jq = jQuery.noConflict();
$jq(document).ready(function () {
    redirect_on_save_func();
});

function redirect_on_save_func() {
    var qvars = get_query_func();
    var nq = [];
    $jq.each(qvars, function (vk, vv) {
        if (vk.match('meta_warning*') == null)
            nq.push(vk + '=' + encodeURIComponent(vv));
    });
    var hr = window.location.href;
    var nqs = hr.split('?')[0] + '?' + nq.join('&');
    window.history.pushState({}, null, nqs);
}

function get_query_func() {
    var pairs = window.location.search.substring(1).split("&"),
        obj = {},
        pair,
        i;
    for (i in pairs) {
        if (pairs[i] === "") continue;
        pair = pairs[i].split("=");
        obj[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1]);
    }
    return obj;
}
