Or you can create buttons with a click function to show the modal or hide the modal.

<button type="button" class="btn btn-success" id="modalOpen">Open</button>

<button type="button" class="btn btn-warning" id="modalClose">Close</button>

On document ready wait for the button clicks:

$(document).ready(function () {
    $("#modalOpen").click(function () {
    $("#modalClose").click(function () {

toggle can also be used, this will show if hidden and hide if shown. However, using this method means you don’t always know or have control of what state the modal is in.

A method to check if a modal is active (shown) or not:

if ($("#theModal").hasClass("show")) {
    alert('is shown');

This checks if the modal has the class show.
