jquery - 慢速向下滚动

Question

好的，所以我找不到任何相关信息。

我知道更改网站的滚动速度很糟糕，但我需要为一个与其说是网站，不如说是游戏的网站这样做。

谁能告诉我如何降低滚动速度？ Jquery 还是 CSS？

编辑:我想更改人们使用鼠标滚轮滚动时的滚动速度。

看这个 fiddle :http://jsfiddle.net/promatik/NFk2L/ ，你可以设置时间和距离!

JS代码

if (window.addEventListener) window.addEventListener('DOMMouseScroll', wheel, false);
window.onmousewheel = document.onmousewheel = wheel;

function wheel(event) {
    var delta = 0;
    if (event.wheelDelta) delta = event.wheelDelta / 120;
    else if (event.detail) delta = -event.detail / 3;

    handle(delta);
    if (event.preventDefault) event.preventDefault();
    event.returnValue = false;
}

function handle(delta) {
    var time = 1000;
    var distance = 300;

    $('html, body').stop().animate({
        scrollTop: $(window).scrollTop() - (distance * delta)
    }, time );
}

if (window.addEventListener) window.addEventListener('DOMMouseScroll', wheel, false);
window.onmousewheel = document.onmousewheel = wheel;

function wheel(event) {
  var delta = 0;
  if (event.wheelDelta) delta = event.wheelDelta / 120;
  else if (event.detail) delta = -event.detail / 3;

  handle(delta);
  if (event.preventDefault) event.preventDefault();
  event.returnValue = false;
}

function handle(delta) {
  var time = 1000;
  var distance = 300;

  $('html, body').stop().animate({
    scrollTop: $(window).scrollTop() - (distance * delta)
  }, time);
}
