javascript - 导航到页面的某个部分

标签 javascript html css

我正在开发一个静态页面并使用 id 和 href 引用导航到各个部分。选择一个部分后，滚动条不会滑入该部分的开头。它隐藏了该部分的标签部分。有人可以帮我弄这个吗。页面中的一些图片无法正常工作，请忽略它们。

var menuObject = document.getElementById("open-menu");
menuObject.addEventListener('click', function() {
  var asideObject = document.getElementById('offcanvas');
  asideObject.classList.add('open');
})
var closeBtn = document.getElementById('close-btn');
closeBtn.addEventListener('click', function() {
  var asideObject = document.getElementById('offcanvas');
  asideObject.classList.remove('open');
  event.preventDefault();
})

最佳答案

您可以像这样向每个部分添加一些填充:

var menuObject = document.getElementById("open-menu");
menuObject.addEventListener('click', function() {
  var asideObject = document.getElementById('offcanvas');
  asideObject.classList.add('open');
})
var closeBtn = document.getElementById('close-btn');
closeBtn.addEventListener('click', function() {
  var asideObject = document.getElementById('offcanvas');
  asideObject.classList.remove('open');
  event.preventDefault();
})
