篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用带有固定位置标题的scrollIntoView相关的知识，希望对你有一定的参考价值。
我有一个标题设置为position: fixed的网站。在我的一个页面上，我在一个元素上使用scrollIntoView(true)。我的问题是，当调用scrollIntoView时，元素位于标题下方。我如何解决这个问题，以便元素显示在标题下方？
我使用的是Bootstrap框架，标题用navbar navbar-fixed-top设计。
答案
这有点hacky但这是一个解决方法。
var node = 'select your element';
var yourHeight = 'height of your fixed header';
// scroll to your element
node.scrollIntoView(true);
// now account for fixed header
var scrolledY = window.scrollY;
if(scrolledY){
window.scroll(0, scrolledY - yourHeight);
}
另一答案
您可以使用CSS解决此问题，方法是将padding-top和负margin-top应用于要滚动到的元素。
Demo
document.querySelector('.scroll-to-working-inline').addEventListener('click', function() {
document.querySelector('.working-inline').scrollIntoView();
});
document.querySelector('.scroll-to-working-block').addEventListener('click', function() {
document.querySelector('.working-block').scrollIntoView();
});
document.querySelector('.scroll-to-broken').addEventListener('click', function() {
document.querySelector('.broken').scrollIntoView();
});body {
margin: 0;
padding-top: 60px;
}
header {
position: fixed;
top: 0;
background-color: tomato;
color: white;
width: 100%;
height: 60px;
line-height: 60px;
text-align: center;
}
[class^='working'],
[class^='broken'] {
font-size: 3rem;
}
.working-inline {
padding-top: 60px;
margin-top: -60px;
}
.working-block {
padding-top: 60px;
margin-top: -60px;
}<header>
scroll to...
<button class="scroll-to-working-inline">working inline element</button>
<button class="scroll-to-working-block">working block element</button>
<button class="scroll-to-broken">broken element</button>
</header>

以下代码生成一个平滑滚动到元素的顶部，并带有固定标题的偏移量：
var topOfElement = document.querySelector('#targetElement').offsetTop - XX;
window.scroll({ top: topOfElement, behavior: "smooth" });
其中XX是固定标题的高度。
另一答案
如果有任何人遇到问题，你的容器div的上边距在scrollIntoView之后被忽略，那么不要将你的元素滚动到视图中，而是相对于其父滚动容器执行scrollTop，如下所示：
var topOfElementToView= $('#elementToScroll').position().top;
$('#parentScrollingContainer').scrollTop(topOfElementToView);
