此代码最初用于在页面加载时平滑滚动到锚点。
尝试添加一个监听器,使其可以单击以滚动到同一页面上的锚点,但是我被卡住了。
// <!--smooth scroll to anchors-->
(function(jQuery){
var jump=function(e){
if (e){
e.preventDefault(); //prevent the "normal" behavior which would be a "hard" jump
var mytarget = jQuery(this).attr("href"); //get the target
}else{
var mytarget = location.hash; //sets the target to the anchor part of a URL
}
jQuery('html,body').animate( //perform animated scrolling
{
scrollTop: jQuery(mytarget).offset().top - 100 //get top-position of target-element and set it as scroll target and move down 100px for fixed nav
}, 1000,function(){ //scrolldelay: 2 seconds
location.hash = mytarget; //attach the hash (#jumptarget) to the pageurl
});
}
jQuery('html, body').hide()
// on load
jQuery(document).ready(function(){
jQuery('a[href^="#"]').bind("click", jump);
if (location.hash){
setTimeout(function(){
jQuery('html, body').scrollTop(0).show()
jump()
}, 0);
}else{
jQuery('html, body').show()
}
});
// on click
var inpage-nav =document.querySelectorAll('.in-page-nav');
for(var i=0;i<cell.length;i++){
inpage-nav[i].addEventListener('click',jump);
}
})(jQuery)
// <!--End smooth scroll-->
页面导航中的HTML:
<div class="just-a-nav">
<ul>
<li class="filter"><a class="in-page-nav" href="#item1">Item 1</a></li>
<li class="filter"><a class="in-page-nav" href="#item2">Item 2</a></li>
<li class="filter"><a class="in-page-nav" href="#item3">Item 3</a></li>
</ul>
</div>

示例HTML:希望这会有所帮助;这是我的小提琴:https://jsfiddle.net/Ledg92c7/
<a href="#goto-1" class="in-page-nav">Go-Target-1</a> | <a href="#goto-2" class="in-page-nav">Go-Target-2</a>
<div id="goto-0" style="height:1200px;background:green">
.....Demo Content 0....
</div>
<div id="goto-1" style="height:300px;background:red">
.....Demo Content 1....
</div>
<div id="goto-2" style="height:400px;background:blue">
.....Demo Content 2....
</div>
