Question

我正在使用指令在从详细信息页面返回主页时保留滚动位置。当我按下chrome的后退按钮但当我在详细信息页面中使用“后退”链接时，该指令不起作用。我应该改变什么？这是一些代码：

// Detail.cshtml

    Layout = null;

我通过改变＆＃34; Back＆＃34;解决了这个问题。来自

的链接

 <a class="back" href="/">Back</a>

到

 <a class="back" href="javascript:void()" onclick="window.history.back(1)">Back</a>

角度js保持滚动位置
