Native dialog UI elements enhance user interaction in applications by providing clear communication. In this article, we’ll explore how to use the Cordova plugin for dialogs, allowing you to create custom alerts, confirmations, and prompts in your app.

Getting Started

Before you can dive into creating dialogs, you need to install the Cordova Dialogs plugin. Follow these steps:

• Open your terminal or command prompt.
• Navigate to your project directory.
• Run the following command: cordova plugin add cordova-plugin-dialogs

Once installed, you can reference various dialog methods through the navigator.notification object, which becomes available only after the deviceready event.

Understanding the Dialog Methods

The plugin offers several useful methods:

• navigator.notification.alert
• navigator.notification.confirm
• navigator.notification.prompt
• navigator.notification.beep
• navigator.notification.dismissPrevious
• navigator.notification.dismissAll

How to Create a Custom Alert

Creating an alert is akin to putting a spotlight on an important message that requires the user’s attention. Here’s how you can implement it:

function alertDismissed() {
    // do something
}
navigator.notification.alert(
    'You are the winner!',   // message
    alertDismissed,          // callback
    'Game Over',             // title
    'Done'                   // buttonName
);

In this example, the alert displays a message, a title, and a button labeled “Done.” Once the alert is dismissed, the alertDismissed function is called.

Implementing a Confirmation Dialog

Think of a confirmation dialog as a traffic signal, guiding the user whether to proceed or stop. Use it like this:

function onConfirm(buttonIndex) {
    alert('You selected button ' + buttonIndex);
}
navigator.notification.confirm(
    'You are the winner!',  // message
    onConfirm,              // callback
    'Game Over',            // title
    ['Restart', 'Exit']     // buttonLabels
);

In this code, once the user presses a button, the index of the selected button triggers the onConfirm function, giving immediate feedback on the user’s choice.

Showing a Prompt

A prompt dialog allows users to input data, similar to a suggestion box. Here’s how to do it:

function onPrompt(results) {
    alert('You selected button number ' + results.buttonIndex + ' and entered ' + results.input1);
}
navigator.notification.prompt(
    'Please enter your name',  // message
    onPrompt,                 // callback
    'Registration',           // title
    ['Ok', 'Exit'],           // buttonLabels
    'Jane Doe'                // defaultText
);

This facilitates user input and provides feedback based on the entered value, making your app interactive.

Troubleshooting Common Issues

While working with dialogs, you may encounter some issues such as:

• Dialogs are not displaying: Ensure that you wait for the deviceready event before invoking dialog methods.
• Button functionality is limited: Remember that on Android, the maximum number of buttons is three, and any more will be ignored.
• Title length exceeded: Note that on some platforms, the title for dialogs has character limits which will truncate or ignore excess text.
