Modal Popup In JavaScript With Source Code

The Modal Popup in JavaScript is widely used on many system development for user interactivity in storing and updating data.

The modal will be generic, allowing you to utilize it for whatever reason you see fit.

We will make a simple modal with CSS and JavaScript. In fact, for the feedback option at the end of this lesson, we’ll use the same code and structure as the modal used.

We also tackle on How To Create JavaScript Popup Modals (popup windows) without using a framework or a third-party library.

Lastly, we will create everything from the ground up, allowing us complete control over how it functions and appears.

What is Modal In JavaScript

In JavaScript, Modal is a (popup window or a dialog box) which is displayed on the top of the current web page.

In addition, they are commonly used to drive newsletter signups, display notifications/alerts, and manage register and login forms, among other things.

How To Call Modal Popup In JavaScript?

In the same way, a page can have several open triggers (elements with the data-open attribute).

The related modal dialog should become visible with a fade-in animation each time a trigger is clicked. Keep in mind that the data-open attribute value must match the modal’s ID.

How To Close Modal Popup In JavaScript?

The <button> inside the header has a data-dismiss = “modal” overlay attribute which closes the modal if the user click on it.

Furthermore, you can also use the JS (hide method) to open the modal, just click the launch button and the modal will automatically popup, if you want it too close you just need to click the backdrop button.

Modal Popup In JavaScript With Source Code : Steps on how to create the project

The code given below is for the html module

<button class="trigger">Click here to trigger the modal!</button>

    <div class="modal">

        <div class="modal-content">

              <!-- html markup and event listener-->

            <span class="close-button">&times;</span>

            <h1>Hello, I am a modal!</h1>

        </div>

    </div>

The first is a basic button that, when clicked, causes the modal to appear. Then there’s the modal’s parent container, which is where the modal is stored. Finally, we have the content for the modal, as well as a close button.

The code given below is for the css module

<style>
      .modal {
        position: fixed;
        left: 0;
        top: 0;
        width: 100%;
        height: 100%;
        background-color: rgba(0, 0, 0, 0.5);
        opacity: 0;
        visibility: hidden;
        transform: scale(1.1);
        transition: visibility 0s linear 0.25s, opacity 0.25s 0s, transform 0.25s;
    }
    .modal-content {
         <!-- width and height, width 100 height -->
        position: absolute;
        top: 50%;
        left: 50%;
        transform: translate(-50%, -50%);
        background-color: white;
        padding: 1rem 1.5rem;
        width: 24rem;
        border-radius: 0.5rem;
    }
    .close-button {
        float: right;
        width: 1.5rem;
        line-height: 1.5rem;
        text-align: center;
        cursor: pointer;
        border-radius: 0.25rem;
        <!-- display flex align items center justify content center -->
        background-color: lightgray;
    }
    .close-button:hover {
        background-color: darkgray;
    }
    .show-modal {
        opacity: 1;
        visibility: visible;
        transform: scale(1.0);
        transition: visibility 0s linear 0s, opacity 0.25s 0s, transform 0.25s;
    }
    </style>

The styles should be straightforward, but if you need a refresher, here’s a nice lesson on CSS.

The code given below is for the javascript module

<script>
      const modal = document.querySelector(".modal");
    const trigger = document.querySelector(".trigger");
    const closeButton = document.querySelector(".close-button");

    function toggleModal() {
        modal.classList.toggle("show-modal");
    }

    function windowOnClick(event) {
        if (event.target === modal) {
            toggleModal();
        }
    }

    trigger.addEventListener("click", toggleModal);
    closeButton.addEventListener("click", toggleModal);
    window.addEventListener("click", windowOnClick);
    </script>

Great! The modal should now seamlessly animate between the states if we press the trigger or close button. It’s all about the beautiful animations here.
