jQuery:返回上一页时如何返回到完全相同的滚动位置 [英] JQuery: How to return to the exact same scroll position when going back to previous page

问题描述

我的项目列表很长，当我单击每个项目并返回到主列表时，滚动位置丢失了.

I have a long list of items and when I clicked into each item and return to the main list, the scroll position was lost.

如何使用jQuery返回相同的确切滚动位置?有什么简单的方法吗?

How can I return to the same exact scroll position using jQuery? Is there any easy way to do it?

$(document).ready(function() {

  $('.update-button').click(function (){
    sessionStorage.scrollPos = $(window).scrollTop();
    console.log(sessionStorage.scrollPos);
  });
});

var init = function () {
    //get scroll position in session storage
    $(window).scrollTop(sessionStorage.scrollPos || 0)
};
window.onload = init;

以上是我的代码的样子.我尝试记录位置，sessionStorage.scrollPos为0.我很确定我将页面滚动到某个位置.

Above is what my code looks like. I tried to log the position and sessionStorage.scrollPos was 0. I am pretty sure I scrolled the page to somewhere.

非常感谢您的帮助.

推荐答案

您需要将滚动位置的值存储在sessionStorage(或任何存储)中，并在页面加载时再次使用它.

You need to store value of scroll position in sessionStorage(or any storage) and re use it again on page load.

$(window).scroll(function () {
    //set scroll position in session storage
    sessionStorage.scrollPos = $(window).scrollTop();
});
var init = function () {
    //get scroll position in session storage
    $(window).scrollTop(sessionStorage.scrollPos || 0)
};
window.onload = init;
