syncfusion-javascript-popups

What problem does it solve?

Implementing production-ready popup/dialog UI with Syncfusion EJ2 in TypeScript can be error-prone and time consuming because of accessibility, event lifecycle, positioning, and theme integration concerns. This Skill consolidates authoritative patterns, API usage, and accessibility guidance so developers deliver consistent, accessible dialogs without guesswork.

Core Features & Use Cases

• Modal and Modeless Dialogs: guidance for isModal, overlay behavior, target scoping, and fullscreen display.
• Templates and Utilities: header/content/footer templates, footerTemplate vs buttons, and DialogUtility.alert/confirm usage for quick prompts.
• Advanced UX & Behavior: animations, drag and resize, nested dialogs, focus management, localization/RTL, persistence, and z-index control.
• Events & Validation: beforeOpen/beforeClose/open/close handlers, preventing close for validation, and refresh/dataBind patterns.
• Accessibility & Best Practices: WAI-ARIA roles/attributes, keyboard interaction, screen reader considerations, and WCAG compliance.
• Use case: add an accessible confirmation flow in a TypeScript app that uses a modal Dialog for form validation, shows a confirm prompt via DialogUtility, and persists dialog position between reloads.
