如何在javascript中最小化浏览器

问题描述

我有通知 div（divNotify）包含一些信息和主页中的计时器

Hi i have notification div(divNotify) with some information and a timer in masterpage

   Protected Sub Timer_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
       Try
           Me.GetNotification_Stats()

           ScriptManager.RegisterClientScriptBlock(Me.Page, GetType(String), "Alert", "Show_NotifyDiv();", True)

       Catch ex As Exception
           Me.lblError.Visible = True
           Me.lblError.InnerText = ex.Message
       End Try
   End Sub

divNotify 将在某段时间内显示。

这里我需要当用户最小化浏览器时，他会通过闪烁浏览器通知他并改变颜色浏览器

divNotify will display in some interval of time.
here i need when the user will minimize the browser he will be notified by blinking browser and change color of browser

但首先我如何知道浏览器是否在javasript中最小化
这里我使用jquery for show div tag

but first of all how do i know if the browser is minimized or not in javasripthere i am using jquery for show div tag

  function Show_NotifyDiv() {
            $("#div_NotificationOuter").show(1000);
            $("#div_NotificationOuter").animate({ bottom: '+=30px' }, 4000);
    }

推荐答案

无法确定是否该页面通过JavaScript 最小化，但您可以使用 ，以确定该网页是否可见。

Its impossible to find out whether the page is minimized via JavaScript, but you can use Visibility API to determine, whether the page is visible to user or not.

目前可在Chrome，Mozilla和IE10中使用。

Currently available in Chrome, Mozilla and IE10.
