如何禁用滚动而不使用溢出：隐藏和位置：固定？

Question

Give me solution to disable scroll of the page. Right now I'm using

overflow:hidden

or

position:fixed

I use given code as well:

var keys = { 37: 1, 38: 1, 39: 1, 40: 1 };

function preventDefault(e) {
    e = e || window.event;
    if (e.preventDefault) e.preventDefault();
    e.returnValue = false;
}

function preventDefaultForScrollKeys(e) {
    if (keys[e.keyCode]) {
        preventDefault(e);
        return false;
    }
}

function disableScroll() {
    if (window.addEventListener) // older FF
        window.addEventListener('DOMMouseScroll', preventDefault, false);
    window.onwheel = preventDefault; // modern standard
    window.onmousewheel = document.onmousewheel = preventDefault; // older browsers, IE
    window.ontouchmove = preventDefault; // mobile
    document.onkeydown = preventDefaultForScrollKeys;
}

function enableScroll() {
    if (window.removeEventListener) window.removeEventListener('DOMMouseScroll', preventDefault, false);
    window.onmousewheel = document.onmousewheel = null;
    window.onwheel = null;
    window.ontouchmove = null;
    document.onkeydown = null;
}

but it is not giving me proper output. My page getting fluctuate when I use above code... I don't want to use any library.
