Creating a `Yes/No` Question in Javascript

When building web applications, user interaction is key to creating a seamless experience. One common scenario developers encounter is the need to ask a Yes/No question to users. However, the standard confirm() function in Javascript, while functional, only provides OK/Cancel buttons. So, what can be done to create a more tailored modal box that presents users with clear Yes/No options?

Javascript offers a few built-in modal boxes: alert, confirm, and prompt. However, none of these provide an explicit Yes/No option. Here’s a quick rundown of these options:

alert(): Displays a message to the user with an OK button. Useful for notifications, but does not ask questions.
confirm(): Asks a yes/no question and returns a Boolean (true or false). However, it uses OK/Cancel buttons instead of Yes/No.
prompt(): Allows for user input but isn’t suited for yes/no interactions and only has OK/Cancel buttons.

These built-in functions might not fulfill your specific needs, leading us to explore custom solutions.

To create a Yes/No question prompt, many developers opt for third-party libraries that allow for more customizable dialog boxes. One such solution is ModalBox. Here’s a quick overview of how to implement it:

Using ModalBox

Installation: First, include ModalBox in your project. You can find the library on GitHub here.

HTML Structure: Set up your modal box HTML format. Here’s an example of a simple structure for your modal:

<div id="myModal" class="modal">
    <div class="modal-content">
        <span class="close">&times;</span>
        <p>Are you sure you want to proceed?</p>
        <button id="yesButton">Yes</button>
        <button id="noButton">No</button>
    </div>
</div>

Styling the Modal: Don’t forget to add styles to your modal for better user experience. Here’s a simple CSS example:

.modal {
    display: none; 
    position: fixed; 
    z-index: 1; 
    left: 0;
    top: 0;
    width: 100%; 
    height: 100%;
    overflow: auto; 
    background-color: rgb(0,0,0);
    background-color: rgba(0,0,0,0.4);
}

.modal-content {
    background-color: #fefefe;
    margin: 15% auto; 
    padding: 20px;
    border: 1px solid #888;
    width: 80%;
}

Javascript Functionality: Finally, add the Javascript that will open the modal when needed and handle button clicks:

document.getElementById('myModal').style.display = "block"; // Open the modal

document.getElementById("yesButton").onclick = function() {
    console.log("User clicked Yes");
    // Add your action for "Yes" here
    document.getElementById('myModal').style.display = "none"; 
}

document.getElementById("noButton").onclick = function() {
    console.log("User clicked No");
    // Add your action for "No" here
    document.getElementById('myModal').style.display = "none"; 
}

document.getElementsByClassName("close")[0].onclick = function() {
    document.getElementById('myModal').style.display = "none"; 
}

Conclusion

Creating a customizable Yes/No question in Javascript is possible by utilizing modal box libraries instead of relying solely on built-in functions. Whether you opt for ModalBox or another alternative, these custom solutions provide a better user experience while enhancing interaction on your web applications.

Explore the available libraries and choose the one that fits best with your project’s style and functionality needs, and soon you will be able to engage users with clear, accessible Yes/No questions.
