JQuery simplePagination.js浏览器历史记录

我最近将JQuery的simplePagination.js集成到了我的html中，我很高兴。一切正常。。。。除了浏览器历史记录部分。当点击分页中的页码时，我可以看到浏览器的url栏会根据用户所在的页面而变化。不幸的是，我注意到，当点击浏览器上的"返回"时，url确实会变回上一页，但所选网站的内容和页码不会变回。即1 2 3 4 5接下来是分页按钮。。。如果我按顺序单击它们，并且当前处于4。如果我在浏览器上单击"返回"，突出显示的按钮仍然是4，与4相关的内容也是如此。它没有变回3。唯一变回3的是url。

我最初（几乎）用这个stackoverflow帖子来处理我的代码>>如何使用SimplePagination jquery

在那篇帖子中，用户2unco建议了一些代码，然后附上了一个工作示例。

为了方便起见，我将包括我的例子中提到的所有代码：

要分页的HTML内容：（如果没有翻译成实际内容，就无法找到如何发布html代码）…请参阅这篇文章的HTML代码示例。如何使用SimplePagination jquery建议添加到HTML:的javascript

jQuery(function($) {
    // consider adding an id to your table,
    // just incase a second table ever enters the picture..?
    var items = $("table tbody tr");
    var numItems = items.length;
    var perPage = 2;
    // only show the first 2 (or "first per_page") items initially
    items.slice(perPage).hide();
    // now setup your pagination
    // you need that .pagination-page div before/after your table
    $(".pagination-page").pagination({
        items: numItems,
        itemsOnPage: perPage,
        cssStyle: "light-theme",
        onPageClick: function(pageNumber) { // this is where the magic happens
            // someone changed page, lets hide/show trs appropriately
            var showFrom = perPage * (pageNumber - 1);
            var showTo = showFrom + perPage;
            items.hide() // first hide everything, then show for the new page
                 .slice(showFrom, showTo).show();
        }
    });
});

它"工作"的例子如下：http://bilalakil.me/bin/simplepagination/

如果你尝试一下，你就会看到我的问题。单击第1页，然后单击第2页，再单击第3页。然后单击后退按钮。url将更改，但页面上的内容和突出显示的分页按钮将保持不变。

如何解决这个问题？需要修复它，这样当按下浏览器上的后退按钮时，内容实际上会发生变化，而不仅仅是url字符串。

附言：我已经在Firefox和Chrome中尝试过了。所以我不认为这是浏览器的问题。
