html5桌面通知(Web Notifications)实例解析Html5中的桌面通知Notification的实现HTML5实现桌面通知 提示功能HTML5实现Notification API桌面通知功能 突袭HTML5之Javascript API扩展5—其他扩展(应用缓存/服务端消息/桌面HTML5中的Web Notification桌面通知功能的实现方法

window.addEventListener('load', function () {
// At first, let's check if we have permission for notification
if (Notification && Notification.permission !== "granted") {
Notification.requestPermission(function (status) {
if (Notification.permission !== status) {
Notification.permission = status;
}
});
}
});

Not a Bug, Feature.

Desktop Notifications can only be triggered via a user action. Typing into the
JavaScript console has the same effect as raw javascript code embedded into the web
page (no user action). Typing the javascript into the location bar, however,
represents a user-action (the user is intentionally visiting a javascript link to
enable notifications, probably for sites that tend to use href="javascript：" instead
of onclick="".

I'm pretty sure this is a non-issue.

function showMsgNotification(title, msg){
var Notification = window.Notification || window.mozNotification || window.webkitNotification;

if (Notification && Notification.permission === "granted") {
var instance = new Notification(
title, {
body: msg,
icon: "image_url"
}
);

instance.onclick = function () {
// Something to do
};
instance.onerror = function () {
// Something to do
};
instance.onshow = function () {
// Something to do
// console.log(instance.close);
setTimeout(instance.close, 3000);
};
instance.onclose = function () {
// Something to do
};
}else if (Notification && Notification.permission !== "denied") {
Notification.requestPermission(function (status) {
if (Notification.permission !== status) {
Notification.permission = status;
}
// If the user said okay
if (status === "granted") {
var instance = new Notification(
title, {
body: msg,
icon: "image_url"
}
);

instance.onclick = function () {
// Something to do
};
instance.onerror = function () {
// Something to do
};
instance.onshow = function () {
// Something to do
setTimeout(instance.close, 3000);
};
instance.onclose = function () {
// Something to do
};

}else {
return false
}
});
}else{
return false;
}

}
