How to write (number of notifications) in the address bar when a notification is found
Does any of you k开发者_高级运维now how most of the websites today show the number of notifications in the title bar when a new notification is found? Like if you have a notification on Facebook you get (1) Facebook in the title bar. How could I do that?
This uses simple Javascript. First, the title of the document is stored somewhere so when the title is written to multiple times, it doesn't prepend multiple (1)
s to the title (i.e., you wouldn't want (3) (1) Facebook
). Then it sets document.title
to that original title while putting some bit of information on the front, something like this:
original_title = document.title
// time passes
document.title = "(" + update_count + ") " + original_title;
You can access the title bar by setting it explicitly:
document.title = document.title + ' (' + notificationCount+ ')'
If you mean the title bar, then you can use JavaScript:
var notifications = 2;
document.title = "("+ notifications +") ...";
