百度百科右侧js效果

假设页面上有有几个内容块：

<div id="content1">

<h3>家庭情况</h3>

<div>...</div>

</div>

<div id="content2">

<h3>人物评价</h3>

<div>...</div>

</div>

<div id="content3">

<h3>作品</h3>

<div>...</div>

</div>

控制逻辑 ：


                         var content1 = document.getElementById(‘content1‘);
  
                         var content2 = document.getElementById(‘content2‘);

var content3 = document.getElementById(‘content3‘);

window.addEventListener(‘scroll‘, function() {

// 拿到滚动位置

var scrollY = window.pageYOffset || window.scrollY || document.documentElement.scrollTop;

// 计算悬浮层高亮

if (content3.getBoundingClientRect().top > scrollY) {

// 改变右侧悬浮层高亮content3标题

} else if (content2.getBoundingClientRect().top > scrollY) {

// 改变右侧悬浮层高亮content2标题

} else if (content1.getBoundingClientRect().top > scrollY) {

// 改变右侧悬浮层高亮content1标题

}

}, false);
