jQuery Scroll Down button used to scroll page by 100%

I assume what you want to achieve is scrolling the window as window height.
我假设您想要实现的是将窗口滚动为窗口高度。
But css()is not a global function, it's a jQuery object method.
但css()它不是一个全局函数，它是一个 jQuery 对象方法。
you could get the height of window by .height()method:
您可以通过.height()方法获取窗口的高度：
$('#gdb1').click(function(){
$("html, body").animate({ scrollTop: $(window).height()}, 600);
return false;
});
But If you want to scroll the window right on the top of an element, you could get the needed space by $(selector).offset().top.
但是如果你想在元素的顶部滚动窗口，你可以通过$(selector).offset().top.

You could put a hidden element on the page and always scroll to the top of that element. That would give you much more consistency across browsers.
您可以在页面上放置一个隐藏元素并始终滚动到该元素的顶部。这将为您提供跨浏览器的更多一致性。
