我会说我不够聪明，无法解决这个问题。我正在使用 Twitter 引导程序的 spacelab 版本。我刷新页面的 50% 时间看起来像这样。另一半时间加载正常。这可能是什么原因？？？http://i.imgur.com/8rhDZ.png

当我禁用 JS 时似乎不会发生。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>
