So, that's the settings in there and shows the ask permission does work. I can set it to deny and I can remove it. I can see it now lists MacMost and has it set to allow. I'm going to hit allow and one of the things I am going to look at now is under preferences in notifications. So let's try the first one which is going to ask permission and you can see it comes up with the dialog box. So here I am at this page in Safari and I've got my two links. So I'm I am going to have that call back and let's go and take a look when we go this page in Safari 6. 'On close' is when they dismiss it and 'on show' is when it appears and there may be a delay if the system does not show it immediately and it is good to have that call back and of course 'on error' is self explanatory. So it is the most logical one to use for something in Java Script. On click is what will then happen when they select that. Now 'on click' is what happens when the user gets a little alert and it says close or show me the notification. So you have on click, on show, on close, and on error. So basically it is an ID for the notification and then you can have various functions that react to events. So in this case it will be called test0 if the page for some reason sends test0 more than one time it is not going to list it multiple times. Now this is good because it prevents multiple notifications being sent. The tag is some sort of number or key word that you will use to identify that notification. You also want to have something called the tag.

In this optional set of parameters you have going to have body which is the actual bit of text that will display under the title. Then you have this object here, and it has to be an object with different parameters in it. You use new notification to create notification and the parameters are pretty straight forward. Now here I am testing the permission level so it should be granted in order to continue or otherwise this next command won't have any effect. It will log the permission level as well which should be granted.

The second function is to actually send a notification and this will also test for windows dot notification. It has to have a function in here as the parameter so in this case I am just going to create a simple function that sends again the log to the console so that you can see that they have changed it so the perfect thing would be that it starts off saying default and then it goes and says granted.

So if somebody is going to a browser other than Safari 6 right now then the code inside here won't work and the key thing here is that notification.request permission which will basically put up a dialog box that we will look at soon that will ask the user if the web page can send them notifications. This is testing windows dot notification tells you whether or not the browser has the ability. That's not part of the regular code of course. The third is granted which means they are going to allow notifications so notifications will work.

The second is denied which means they have said no. So it what you are going to get when the user clicks this. The first one is the default which means the user has never done anything to enable to disable notification from this page. Now there are three different permission levels that you need to be concerned about. So the ask function basically it will send to the console here just the permission level so that I can see what the permission level is. Then I've got here at the bottom some very simple links here to trigger either one of these. The first is going to ask the user permission to send notification from this web page. Of course this would be in a dot JS file normally. It is just a matter of knowing the right Java Script to put in there. Using Java Script on your web pages you can use the Mountain Lion notifications feature along with Safari 6.

On today's episode let's look how to implement notifications using Safari 6 and Java Script.
