Frequently Asked Questions about window-alert-confirm

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
When should I use window.alert versus window.confirm for web application notifications?▼

Use window.alert for simple error notifications and window.confirm to verify destructive actions. For complex UX flows, choose custom modal dialogs to ensure better accessibility and cross-browser behavior.

How do I make browser dialogs accessible for screen reader and keyboard navigation?▼

To make browser dialogs accessible, ensure proper focus management and screen reader compatibility. Native alert and confirm dialogs handle focus automatically, but custom implementations require manual keyboard navigation and focus management.

What are the cross-browser behavior caveats when using JavaScript alert and confirm?▼

Cross-browser behavior caveats for JavaScript alert and confirm include differences in dialog styling, focus trapping, and blocking behavior. Test across browsers to ensure consistent UX for error notifications and destructive action confirmations.

Are native browser dialogs or custom modal dialogs better for UX?▼

Native browser dialogs are better for simple UX scenarios like basic error notifications. Custom modal dialogs are preferable for complex UX needs, offering controlled styling and consistent accessibility across browsers.

Why does window.confirm block browser execution and when should I avoid it?▼

window.confirm blocks browser execution because it operates synchronously. Avoid using window.confirm when you need non-blocking UX or when implementing custom modal dialogs for complex destructive action confirmations.
