我要说我不够聪明,不能把这个搞清楚。我正在使用Twitter的bootstrap的spacelab版本。刷新页面的50%的时间看起来像这样。另一半时间加载罚款。什么可能导致这??? ??? http://i.imgur.com/8rhDZ.png
当我禁用JS时似乎没有发生。哪个脚本可能是罪魁祸首?
<script>
$(document).scroll(function(){
// If has not activated (has no attribute "data-top"
if (!$('.subnav').attr('data-top')) {
// If already fixed, then do nothing
if ($('.subnav').hasClass('subnav-fixed')) return;
// Remember top position
var offset = $('.subnav').offset()
$('.subnav').attr('data-top', offset.top);
}
if ($('.subnav').attr('data-top') - $('.subnav').outerHeight() <= $(this).scrollTop())
$('.subnav').addClass('subnav-fixed');
else
$('.subnav').removeClass('subnav-fixed');
});
</script>
