此代码用于向下/向上导航页面。这一切都正常,我希望它能更轻松一些。一些看起来好一点的动画。有任何想法吗??
<script type="text/javascript">
$(function(){
function scroll(direction) {
var scroll, i,
positions = [],
here = $(window).scrollTop(),
collection = $('.part');
collection.each(function() {
positions.push(parseInt($(this).offset()['top'],10));
});
for(i = 0; i < positions.length; i++) {
if (direction == 'next' && positions[i] > here) { scroll = collection.get(i); break; }
if (direction == 'prev' && i > 0 && positions[i] >= here) { scroll = collection.get(i-1); break; }
}
if (scroll) {
$.scrollTo(scroll, {
duration: 350
});
}
return false;
}
$("#next,#prev").click(function() {
return scroll($(this).attr('id'));
});
$(".scrolltoanchor").click(function() {
$.scrollTo($($(this).attr("href")), {
duration: 350
});
return false;
});
});
