登台服务器上的LocalStorage为空。 IIS7

Question

虽然让页面闲置很长时间，比如说10-15分钟，页面上的localstorage显示为“null＆＃39;。

我的代码就是那个

LocalStorageFunc函数正在调用文档。

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

我没有找到任何特殊原因，为什么localStorage值为页面名称和页面标题获取null。虽然我从来没有打开带有多个标签的页面，但登录用户的会话也不会过期。 Browser: chrome latest version。

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

在页面加载时创建菜单项，然后单击菜单以更新本地存储值
