The toast component is recently proposed in Bootstrap 4. Additionally, toasts are opt-in for performance cause, like a tooltips, so you must subscribe them yourself with toast() method. Also, toasts will directly hide after 500 milliseconds (0.5 second), if you do not specify autohide: false. Now ,you can look how to designed a toast in any web page.

Step 1: Adding the Toast Markup

Toasts markups are pretty straightforward. The following example will explain you how to make a toast component with a header, body, and a close button. <script> $(document).ready(function(){ $(“.show-toast”).click(function(){ $(“#myToast”).toast(‘show’); }); }); </script>

Step 2: Triggering the Toasts

Toasts can be triggered via JavaScript — just call thetoast() Bootstrap method commonly used with the class, id or any CSS selector or any CSS selector of the target element in your JavaScript code.. <script> $(document).ready(function(){ $(“#myToast”).toast(‘show’); }); </script>

Stacking Toasts Vertically

Multiple toasts are vertically stacked in a readable manner automatically. Here’s an example:

Code:-

Example:-

 Hello, Gurukul Zone SRCS!Online×These are simple toast text. Hello,Gurukul Zone SRCS!5 minutes ago×See? This is other toast message.

Placement of Toasts

You can place toasts anywhere on your web page using custom CSS. However, the top right or top middle side is recommended for notifications. Also, if you only want to show one toast at a time, put the positioning styles inline i.e. directly on the .toast element. Hello, Gurukul Zone SRCS!just now×This is a easy toast message. Hello,Gurukul Zone SRCS!5 minutes ago×See? This is one more toast message.

Options

There are certain options which may be passed to toast() functionality of a toast. Options can be passed via data attributes or JavaScript.

Data attributes provides an easy way for setting the toast options, however JavaScript is the more preferable way as it prevents you from repetitive work. See the .toast(options) method in the section below to know how to set the options for toasts using JavaScript.For setting the toast options via data attributes, just append the option name to data-data-autohide=”false”, data-delay=”3000″, etc. etc.

 Methods
