我正在尝试使滚动到顶部平滑，但我提供的代码似乎不起作用。滚动只是不顺利...
$(function() {
$('a[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) {
var targetOffset = $target.offset().top;
$('html,body').animate({
scrollTop: targetOffset
}, 1000);
return false;
}
}
});
});<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<a name="top" id="top"></a>
<div style="height:2000px">
a hell lot of content here
</div>
<a href="#top">back to top</a>
为什么它不起作用？

您必须使用||代替&amp;&amp;并进行一些细微更改
校正：
$(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;
}
}
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
