现在我正在建立一个咨询网站，我正在使用Bootstrap，网站只包含一个页面，为了更加实用，我将一些按钮放在导航栏中固定顶部和目标那就是当你点击按钮，页面滚动到主题，但我有一个问题，当我点击两次它似乎有一个错误，当我在一个特定的主题，我想改变点击另一个按钮，页面滚动错误，像几个像素更高（?????）。我真的不知道发生了什么，我尝试了每一个js修复，没有任何帮助我。
这是我的代码：
$(document).ready(function() {
setBindings();
});
function setBindings() {
$("nav a").click(function(e) {
//e.preventDefault();
e.preventDefault();
var sectionID = "conteudo-" + e.currentTarget.id;
$("html body").animate({
scrollTop: $("#" + sectionID).offset().top
}, 1000)
})
}html,
body,
.capa {
height: 100%;
overflow: auto;
width: 100%;
}
body {
background-attachment: fixed;
font-family: Helvetica, Arial, sans-serif;
overflow-x: hidden;

非常有趣的行为......我花了一段时间才弄清楚，但罪魁祸首是css ..删除css你给它的高度和宽度100％，它工作正常。
<style>
body {
background-attachment: fixed;
font-family: Helvetica, Arial, sans-serif;
overflow-x: hidden;
}
</style>
$(document).ready(function() {
$("nav").find("a").click(function(e) {
e.preventDefault();
var section = $(this).attr("href");
$('html, body').animate({
scrollTop: $(section).offset().top
}, 2000);
});
});
