$(window).scroll(function() {
        $(body).scrollTop = 3000px;
})

The scrollTop property only accepts an integer (not pixels). Omit the px and it should be fine.

scrollTop属性只接受整数(不是像素)。省略px它应该没问题。

$(window).scroll(function() {
    $('body').get(0).scrollTop = 3000; // note that this does only work if body has overflow
    // if it hasn't, use window instead
});

There is a plugin for JQuery called ScrollTo that might do exactly what you need.

有一个名为ScrollTo的JQuery插件可能完全符合您的需求。
