In today's digital age, user experience is more important than ever. As developers, it is our responsibility to ensure that our users have a seamless and intuitive experience while using our websites and applications. One aspect of user experience that often gets overlooked is the use of pop-up dialogs. These small windows can serve as important prompts or warnings for users, but they can also disrupt the flow of the user's interaction with our website or app. In this article, we will explore how to create a custom "confirm" dialog and pause JavaScript execution until the user clicks the confirmation button.
First, let's define what a "confirm" dialog is. It is a type of pop-up window that asks the user to confirm an action before proceeding. For example, when a user clicks on the "delete" button, a "confirm" dialog will appear asking them if they are sure they want to delete the selected item. This is a common practice in web development to prevent accidental or irreversible actions.
To create our custom "confirm" dialog, we will need to use HTML, CSS, and JavaScript. Let's start with the HTML. We will need a container element to hold our dialog and two buttons - one for confirming the action and one for canceling it.
<div id="confirm-dialog">
<p>Are you sure you want to delete this item?</p>
<button id="confirm-btn">Confirm</button>
<button id="cancel-btn">Cancel</button>
</div>
Next, we will use CSS to style our dialog and buttons to make them visually appealing and fit in with the overall design of our website or app.
#confirm-dialog {
width: 300px;
height: 150px;
background-color: #fff;
border: 2px solid #000;
border-radius: 5px;
padding: 20px;
text-align: center;
font-size: 18px;
}
#confirm-btn, #cancel-btn {
background-color: #4285F4;
border: none;
border-radius: 5px;
color: #fff;
font-size: 16px;
padding: 10px 20px;
margin: 10px;
cursor: pointer;
}
#confirm-btn:hover, #cancel-btn:hover {
background-color: #3367D6;
}
Now, let's add some JavaScript to make our dialog functional. We will use the built-in "confirm" function in JavaScript, which displays a default "confirm" dialog with a message and two buttons - "OK" and "Cancel". We will also add an event listener to our custom "confirm" button to execute the action only if the user clicks on the "confirm" button.
const confirmBtn = document.getElementById("confirm-btn");
const cancelBtn = document.getElementById("cancel-btn");
confirmBtn.addEventListener("click", confirmAction);
function confirmAction() {
// Execute the action
}
cancelBtn.addEventListener("click", cancelAction);
function cancelAction() {
// Close the dialog without executing the action
}
Now, we have a functional custom "confirm" dialog that will pause JavaScript execution until the user clicks on the "confirm" or "cancel" button. But what if we want to display our own custom message instead of the default "confirm" message? We can do that by using the "window.prompt" function in JavaScript. This function takes two arguments
