我在将平滑滚动JS集成到一个简单的网页http://www.asiweb.com/iPad/demo/index.html
时遇到了一些麻烦让我感到困扰的是，我使用完全相同的代码完美地在不同的网站上工作。我带来了相同的文件并在代码中复制，但不是滚动它只是捕捉到锚链接。我知道创建原始文件的人已经更新了它，我尝试以各种形式使用更新，但没有成功。我想知道是否有什么东西妨碍了脚本，所以我删除并放回代码的不同部分也没有成功。你有任何建议都会很棒！

看起来您在链接到actuall smoothscroll脚本之前尝试运行smoothscroll。
尝试相反的方式
<script src="js/jquery-1.11.1.min.js"></script>
<script defer src="../jquery.flexslider.js"></script>
<script src="js/smooth-scroll.js"></script>
<script>
smoothScroll.init();
</script>

对于其他感兴趣的人，我无法获得我曾经工作的代码，但我能够使用css-tricks.com中的这个位找到不同的解决方案：
$(function() {
$('a[href*=#]:not([href=#])').click(function() {
if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {
var target = $(this.hash);
target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
if (target.length) {
$('html,body').animate({
scrollTop: target.offset().top
}, 1000);
return false;
}
}
});
});
