js和jquery 实现网站来消息网站标题闪动提示

 

 

 js版

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
  <meta charset="UTF-8">
    <title>无标题页</title>
   <script>


//页面激活判断
var hiddenProperty = 'hidden' in document ? 'hidden' :    
    'webkitHidden' in document ? 'webkitHidden' :    
    'mozHidden' in document ? 'mozHidden' :    
    null;
var visibilityChangeEvent = hiddenProperty.replace(/hidden/i, 'visibilitychange');
var onVisibilityChange = function(){
    if (!document[hiddenProperty]) {    
        console.log('页面非激活');
    }else{
        alert('页面激活')
        console.log('页面激活');
    }
}
document.addEventListener(visibilityChangeEvent, onVisibilityChange);



//网站标题闪动提示
var g_blinkid = 0;
var g_blinkswitch = 0;
var g_blinktitle = document.title;
var g_onlineuser = "";
var g_sysmsg_sound = null;
var g_newmsg_sound = null;
var g_app_num = 0;
var g_appnum = 0;
var g_bappmore = false;
var g_inputtime = 0;
function blinkNewMsg()
{

 document.title = g_blinkswitch % 2==0 ? "【　　　】 - " + g_blinktitle : "【新消息】 - " + g_blinktitle;
 g_blinkswitch++;
 


}

 g_blinkid = setInterval(blinkNewMsg, 1000);

function stopBlinkNewMsg()
{

    if (g_blinkid)
    {
        clearInterval(g_blinkid);
        g_blinkid = 0;
        document.title = g_blinktitle;
    }
}

</script>


</head>
<body>
    <form id="form1" runat="server">
    <div>
        <input id="Button1" type="button" value="button" onclick="stopBlinkNewMsg();" />
    </div>
    </form>
</body>
</html>

 

 

jquery版，记得要引入jquery.js

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
<html> 
<head> 
  <meta charset="UTF-8">
<base href="<%=basePath%>"> 
<title>网页标题</title> 
</head> 
<body> 
<p style="text-align: center;"> 
请看网页标题处效果！ 
<br /> 
隔10秒后提示消失 
</p> 
<script type="text/javascript" src="jquery-3.1.1.min.js"> 
</script> 
<script type="text/javascript"> 

(function($) { 
$.extend( { 
/** 
* 调用方法： var timerArr = $.blinkTitle.show(); 
* $.blinkTitle.clear(timerArr); 
*/ 
blinkTitle : { 
show : function() { //有新消息时在title处闪烁提示 
var step = 0, _title = document.title; 
var timer = setInterval(function() { 
step++; 
if (step == 3) { 
step = 1 
} 

if (step == 1) { 
document.title = '【　　　】' + _title 
} 

if (step == 2) { 
document.title = '【新消息】' + _title 
} 

}, 500); 
return [ timer, _title ]; 
}, 
/** 
* @param timerArr[0], timer标记 
* @param timerArr[1], 初始的title文本内容 
*/ 
clear : function(timerArr) { //去除闪烁提示，恢复初始title文本 
if (timerArr) { 
clearInterval(timerArr[0]); 
document.title = timerArr[1]; 
} 

} 
} 
}); 
})(jQuery); 

jQuery(function($) { 
var timerArr = $.blinkTitle.show(); 
setTimeout(function() { //此处是过一定时间后自动消失 
$.blinkTitle.clear(timerArr); 
}, 10000); 
//若认为操作消失，只需如此调用： $.blinkTitle.clear(timerArr); 
}); 
</script> 
<br />

如不能显示效果，请按Ctrl+F5刷新本页
