Question

基本上所有锚点href都有效，除了scrollspy不起作用。数据偏移也不起作用。只有点击第一个li'主页'正在改变其背景，其他所有人都无法正常工作。当向下滚动到#search-nav #obqvi #about时，与它们相关的菜单按钮也不会变色，这意味着我的scrollspy根本不起作用。

此外，当我单击其中一个锚点时，整个标题菜单按钮重新加载它会发生大约0.1秒，但它很难看。

HTML：

    <body data-spy="scroll" data-target=".navbar" data-offset="0">
            <header>
                <nav class="navbar navbar-fixed-top">

使用Jquery脚本编辑但是当我点击“a”时它仍然无法正常工作我可以顺利滚动到正确的位置但是当我使用滚轮滚动时，与该部分相关的按钮不会变色并且在点击时它也不会变色

JS：

<script>
            $(document).ready(function(){

                $('.btn-information').click(function(){
                    $('#myModal').modal('show');
                });             
                 // Add scrollspy to <body>
            $('body').scrollspy({ target: ".navbar", offset: 50 });

            // Add smooth scrolling on all links inside the navbar
            $("#myNavbar a").on('click', function (event) {

                // Prevent default anchor click behavior
                event.preventDefault();

                // Store hash
                var hash = this.hash;

                // Using jQuery's animate() method to add smooth page scroll
                // The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
                $('html, body').animate({
                    scrollTop: $(hash).offset().top
                }, 800, function () {

                    // Add hash (#) to URL when done scrolling (default click behavior)
                    window.location.hash = hash;
                });
            });
            });

我不知道它是否会有所帮助，但是当我使用滚动间谍功能时，我必须在我的js中包含以下内容。另外 - 检查你是否有滚动间谍所需的文件，并且jquery已加载并首先调入页面。

// jQuery for page scrolling feature - requires jQuery Easing plugin
$(function() {
    $('a.page-scroll').bind('click', function(event) {
        var $anchor = $(this);
        $('html, body').stop().animate({
            scrollTop: $($anchor.attr('href')).offset().top
        }, 1500, 'easeInOutExpo');
        event.preventDefault();
    });
});

// Highlight the top nav as scrolling occurs
$('body').scrollspy({
    target: '.navbar-fixed-top'
})
