默认情况下，如何使容器中的滚动从某个链接开始

https://codepen.io/jimjamjom/pen/oBoEgz

请参阅上面的代码笔。基本上，当有人访问该页面时，默认情况下应将容器设置为"第 3 节"，然后他们需要向上或向下滚动以查看其余部分。

我已经尝试过了，但失败了。

<li class="active">
<a href="#section3">Section 3</a>
</li>

您可以在 DOM 准备就绪时使用此代码

$(document).ready(function(){
  window.location.hash = "#" + "section3";
});

检查笔

有两种方法。

1. 创建永久链接。

将要访问的 URL 设置为www.myawesomesite.com/#section3

2. 使用 javascript 在加载时滚动页面。

将此代码添加到脚本中。

$(window).load(function() {
   $('html, body').animate({
      scrollTop: $('#section3').offset().top}, 1000);
});

它会在页面加载时将页面滚动到 #section3 的顶部位置。

如果您确定您的内容位于页面的最底部，则可以将其添加到页面的onload函数中

window.scrollTo(0,document.body.scrollHeight);

您有两个选择，第一个选项使您的初始 http 请求包含这样的#section3

您也可以将其添加到您的身体中

<body onload="window.location.href="#section3">
