HTML 5 通知在 chrome 中本地不起作用？
jan*_*jan 5 html javascript google-chrome
我找到了以下 HTML 通知示例，它在 Chrome 和 Firefox 中运行良好。下载并在本地尝试后，它不再在 Chrome 中工作。这是预期的行为（Chrome 出于某种原因在本地阻止通知）还是有任何其他原因导致这不起作用？
<!DOCTYPE html>
<html>
<body>
<button onclick="notifyMe()">Notify me!</button>
<script>
function notifyMe() {
// Let's check if the browser supports notifications
if (!("Notification" in window)) {
alert("This browser does not support desktop notification");
}
// Let's check if the user is okay to get some notification
else if (Notification.permission === "granted") {
// If it's okay let's create a notification
var notification = new Notification("Hi there!");
}
// Otherwise, we need to ask the user for permission
// Note, Chrome does not implement the permission static property
// So we have to check for NOT 'denied' instead of 'default'
else if (Notification.permission !== 'denied') {
Notification.requestPermission(function (permission) {
// Whatever the user answers, we make sure we store the information
if(!('permission' in Notification)) {
Notification.permission = permission;
}
// If the user is okay, let's create a notification
if (permission === "granted") {
var notification = new Notification("Hi there!");
}
});
}
}
</script>
</body>
</html>
