The editor was fortunate enough to see such code on a certain awesome technology blog, based on the jquery framework.

<head> 
<base href="<%=basePath%>"> 
<title>My JSP 'test.jsp' starting page</title>

请看网页标题处效果！

<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>
