Introduction

In my recent MEAN stack project, I wanted to notify the end-user based on events. While researching further on this, I came across toastr.js. This library, I found to be very simple and easy to use. Importantly in today’s world of responsive sites, these notification are also responsive.

How to use toaster in short?

  • Add a reference to toastr.js from CDN or from the downloaded package.
  • Add a link to toastr.css and toaster-responsive.css to the HTML page.
  • In JavaScript, to generate toaster notification use below command,
toastr.success('Welcome to toaster notifications!', 'Toastr Notification').
This will show the following toaster notification on your Html page,
  • While displaying these notifications, the toaster library provides us various options e.g. Toastr Type as Success, Warning, Info, Error, etc. And positions can also be decided in a simplistic manner. You can refer to detailed toaster options at toastr.js.
  • Refer to the following section for the demonstration of toaster types and positions.
JSFiddle based sample code
If you want to just play with sample implementation, JSFiddle based implementation can be seen here.
Detailed Code Implementation goes as below,
  1. Create HTML page, toastrsample.html, and copy-paste below code to it.
    1. <!DOCTYPE html>
    2. <html>
    4. <head>
    5. <meta http-equiv="content-type" content="text/html; charset=UTF-8">

  2. Create JavaScript file (toastrsample.js) and add the following code,
    1. $(function()
    2. {
    3. $('#showtoast').click(function()
    4. {
    5. toastr.options =
    6. {
    7. "debug": false,
    8. "positionClass": $("#toastrPositionGroup input:radio:checked").val(),
    9. "onclick": null,
    10. "fadeIn": 300,
    11. "fadeOut": 100,
    12. "timeOut": 3000,
    13. "extendedTimeOut": 1000
    14. }
    16. var d = Date();
    17. toastr[$("#toastrTypeGroup input:radio:checked").val()](d, "Current Day & Time");
    18. });
    19. });
  3. Create Stylesheet file (toastrsample.css) and add the following code,
    1. body
    2. {
    3. font - family: Verdana;
    4. font - size: small;
    5. }
    After running the code and on click of button ‘Show Toastr Notification’, you should see toaster notifications appearing based on Toastr Type and Position you choose.
