Bootstrap 4 Modal Video Autoplay and Stop When Closed

The video modal can be created using the Bootstrap modal class. The modal video popup consists of a video in a dialog box.

Prerequisite: Create a Modal

To create a modal, add the following code:

  • First, add a “<div>” element with the class “container”.
  • Inside it, add an “<img>” element with the “src”, “width”, “data-toggle”, “data-src”, and “data-target” attributes.
  • After that, include a “<div>” element with the classes “modal” and “fade”. The “modal” class creates the modal window and the “fade” class adds fade animation
  • Add a “<div>” element with the class “modal-dialog”.
  • Then, specify a “<div>” element with the class “modal-content”.
  • Use the class “modal-body” for the modal body.
  • Add the close button by using the class “close”. The “&times;” entity code is utilized to add a cross symbol.
  • Then, add the “<iframe>” element in the “<div>” tag and assign the class “embed-responsive” and “embed-responsive-16by9” for responsive video.
  • Associate the “id”, “width”, “height”, “src”, “title”, “frameborder”, “allow”, and “allowfullscreen” attributes with the “<iframe>” element. The “autoplay” keyword is utilized to start the video automatically:
<div class="container">

<img src="/img/play-2297762_1280.png" width="100" class="video-play-btn" data-toggle="modal" data-src="" data-target="#myModal">

<div class="modal fade" id="myModal">

<div class="modal-dialog">

<div class="modal-content">

<div class="modal-body">

<button type="button" class="close" data-dismiss="modal">

<span aria-hidden="true">&times;</span></button>

<div class="embed-responsive embed-responsive-16by9">

<iframe id="video" width="640" height="360" src="" title="Futuristic HUD" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe>



Add the JavaScript Code

To add proper functionality, add the JavaScript code by following the instructions:

  • Add a “<script>” element.
  • Inside it, add a “$(document).ready()” which runs only once the DOM executes the JavaScript.
  • Create a variable “videoPath” and assign the “src” of the data to the variable on click.
  • Then, access the element by id and apply “”. This will display the modal and trigger the function. The function assigns the src of the “videoPath” variable to the “<iframe>” element’s id. In our scenario, the “src” of the “videoPath” variable is assigned to the id “video”.
  • To hide the modal window, the “” is used with the function. This function assigns the empty value to the “<iframe>” element’s id “video”:

 $(document).ready(function () {
var videoPath;
 $(".video-play-btn").click(function () {
  videoPath = $(this).data("src");
 $("#myModal").on("", function (e) {
  $("#video").attr("src", videoPath);
 $("#myModal").on("", function (e) {
  $("#video").attr("src", "");
