通知用户JavaScript中是否有新内容 [英] Notify user if there is something new in JavaScript

问题描述

我想用Javascript创建类似的东西，如果我可以使用Extjs来做的话，它会更好:

I would like to create something like this in Javascript, and its better if i can do it with Extjs:

当页面包含新内容时，在按钮上显示一个小的通知图标，然后当用户单击此按钮并打开页面时，该图标消失了.

showing a small notification icon on a button when the page contains something new, then when the user click this button and open the page, the icon gone.

这是简单的HTML5/JavaScript.我每周都会更新网页，希望用户注意到这些更新.

It's simple HTML5/JavaScript. I update the web page weekly and would like users to notice the updates.

推荐答案

这是可能的.您必须在您的计算机中保存 Cookie 用户单击按钮后浏览器.如果设置了Cookie，则可以隐藏通知.

This is possible. You have to save a Cookie in your browser once the user click the button. If the Cookie is set, then you can hide the notification.

这里有个例子:

var myCookie = Ext.util.Cookies.get("YourCookieName");
if(!myCookie){
    // show notification
}

然后在按钮上单击:

Ext.util.Cookies.set("YourCookieName", 1);
