<button id="tip1" class="tip1">显示通知</button>
<script>
$(function() {
var timer = null,
title = $('title').text();
$('#tip1').on('click', function() {
showMsgNotification('这是标题-》来自开心洋葱', '这里是消息内容，来源自开心洋葱网站，百度搜索《开心洋葱》，网址http://75271.com');
return false;
});
$('body').on('click', function() {
clearInterval(timer);
$('title').text(title);
});
function showMsgNotification(title, msg) {
var Notification = window.Notification || window.mozNotification || window.webkitNotification;
if(Notification) {//支持桌面通知
if(Notification.permission == "granted") {//已经允许通知
var instance = new Notification(title, {
body: msg,

});
instance.onclick = function() {
$('body').css({'background': 'red'});
console.log('onclick');
instance.close();
};
instance.onerror = function() {
console.log('onerror');
};
instance.onshow = function() {

};
instance.onclose = function() {

};
}else {//第一次询问或已经禁止通知(如果用户之前已经禁止显示通知，那么浏览器不会再次询问用户的意见，Notification.requestPermission()方法无效)
Notification.requestPermission(function(status) {
