Jquery 暂存服务器上的LocalStorage为空。IIS7

当页面长时间处于空闲状态（例如10-15分钟）时，页面上的localstorage显示“null”

我的密码是

LocalStorageFunc

函数正在调用documentready

function LocalStorageFunc(MenuTitle, LinkName) {
   // alert('MenuTitle--' + MenuTitle + 'LinkName----' + LinkName);
    localStorage.setItem("PageTitle", MenuTitle);
    localStorage.setItem("PageName", LinkName);
}

我还没有找到任何特定的原因来解释为什么页面名称和页面标题的localStorage值变为null。虽然我从来并没有打开过多个标签页，但对于登录的用户，会话也不会过期。

浏览器：chrome最新版本

  $(document).ready(function () {
        if (localStorage.getItem("PageTitle") != null || localStorage.getItem("PageName") != "") {
            $("#pageTitle").text(localStorage.getItem("PageTitle"));
            $("#PageName").text(localStorage.getItem("PageName"));
        }
    });

在页面加载上创建菜单项，然后单击菜单更新本地存储值

最后两行何时调用？更新的代码请检查调用LocalStorageFunc函数的位置。它没有在代码中显示为document.ready函数。您是否检查了chrome资源？我已经更新了代码，我正在从json对象创建页面加载菜单，当我单击菜单项时，我调用LocalstorageFun根据菜单单击更新页面名称和标题。
