Bootstrap Sticky Notifications AngularJS Service

In this article we will learn about Bootstrap 3.0 Sticky Alerts using Angular JS service.

Introduction

Let's face it, your users need sweet little notifications to keep them all warm and fuzzy inside. The following angualrJs code snippet allows you to send such messages with ease and class. Quickly notify a user of software updates, process completions, or annoy them with registration reminders. This AngularJS directive handles notifications that are easy to create; alert, success, error, warning, information and confirmation messages as an alternative to the standard alert dialogue. Each notification is added to a queue. (Optional). The notifications can be positioned anywhere with ease using CSS.

Points of Interest

 

  1. The same type of notifications is only active on the screen once in case there are multiple clicks.
  2. The Close button results in the removal of the notification from the queue.
  3. A Timeout value can be increased or decreased depending on needs.
