Question

I’m using pines notify (somewhat irrelevant to my issue, I imagine) to create notifications on the change event of a drop down list. On the server side, the change is saved to a database, then when the save is complete – I wish to remove the notification (or do something else depending on the result).

The problem is in creating the notification object in a way that I can later reference it (to remove it).

My intended solution would obtain the id of the dropdownlist, prepend ‘pn’ to it and use that as the variable name, much like

var pnid = 'pn' + $('#mydropdown').attr('id');
notifications[pnid] = createNotification();

In the codebehind I can create javascript code knowing what the notification object will be called. However I’m struggling with my ‘notifications’ object.. I’ve tried this[notifications], window[notifications] etc. to no avail (ie I cannot later reference this object to interact with it) . I’m creating that object outside of any functions like so

var notifications = {};

Am I going about this the completely wrong way?

Answer 1

You can use this line before reaching notifications object.

window.notifications = window.notifications || {};

This will help you create the object if it is undefined and it will also prevent you from overriding it if it already exists.

Note : I assume you have to use this object as a global variable.
