When developing modern web applications, it's common to require user confirmation for certain actions, especially when they involve critical changes or deletions. The DevExtreme library provides a flexible way to implement confirmation dialogs, including the ability to add custom text fields for additional user input. This article will guide you through creating a confirmation dialog using DevExtreme that includes a text field.
Setting Up DevExtreme
Before you start, ensure that you have DevExtreme installed in your project. You can include it via a CDN link or install it through npm:
npm install devextreme
Creating a Confirmation Dialog
Step 1: Include Necessary Scripts and Styles
In your HTML file, make sure to include the necessary DevExtreme styles and scripts:
<link rel="stylesheet" href="https://cdn3.devexpress.com/jslib/21.2.6/css/dx.light.css">
<script src="https://cdn3.devexpress.com/jslib/21.2.6/js/dx.all.js"></script>
Step 2: HTML Structure
Create a basic HTML structure for your confirmation dialog. You can use a div as a container for the dialog:
<div id="confirmDialog" style="display: none;">
<p>Are you sure you want to proceed?</p>
<input type="text" id="confirmationInput" placeholder="Type something..." />
</div>
Step 3: Initialize the Confirm Dialog
Now, you can initialize the dialog using JavaScript. This setup involves configuring the dialog options and handling user input.
$(function() {
$("#confirmDialog").dxDialog({
title: "Confirmation",
visible: false,
width: 400,
height: 250,
buttons: [
{
text: "Cancel",
onClick: function() {
$("#confirmDialog").dxDialog("hide");
}
},
{
text: "OK",
onClick: function() {
const userInput = $("#confirmationInput").val();
if (userInput) {
console.log("User input:", userInput);
// Proceed with the action
} else {
alert("Please provide input before proceeding.");
}
$("#confirmDialog").dxDialog("hide");
}
}
]
});
});
// Function to show the dialog
function showConfirmDialog() {
$("#confirmDialog").dxDialog("show");
}
Step 4: Triggering the Dialog
You can trigger the confirmation dialog by calling the showConfirmDialog() function when a user clicks a button or performs an action:
<button onclick="showConfirmDialog()">Delete Item</button>
Conclusion
Using DevExtreme's capabilities, you can create a confirmation dialog that not only asks for user confirmation but also captures additional input through a text field. This is particularly useful for scenarios where user feedback or additional details are required.
Feel free to customize the dialog's appearance and behavior further by exploring additional properties and methods provided by DevExtreme. This example serves as a solid foundation for integrating interactive confirmation dialogs into your web applications.
