リロードせずに JavaScript で URL のハッシュを簡単に削除する方法

function removeHash () {
    history.pushState("", document.title, window.location.pathname
                                                       + window.location.search);
}

function removeHash () {
    var scrollV, scrollH, loc = window.location;
    if ("pushState" in history)
        history.pushState("", document.title, loc.pathname + loc.search);
    else {
        // Prevent scrolling by storing the current scroll offset
        scrollV = document.body.scrollTop;
        scrollH = document.body.scrollLeft;

        loc.hash = "";

        // Restore the scroll offset to prevent flickering
        document.body.scrollTop = scrollV;
        document.body.scrollLeft = scrollH;
    }
}
