Overview

The JavaScript Modal Dialog is a useful user interface (UI) control for informing users about critical information, errors, warnings, and questions, as well as confirming decisions and collecting input from users. The control has a rich set of built-in features such as action buttons, positioning, animations, dragging, resizing, templating, and more with mobile dialog support. The dialog provides two different types: modal dialogs and non-modal dialogs (modeless) based on interactions.


The JavaScript dialog control comes with two different types of dialogs, modal and non-modal (modeless):

  • Modal dialogs force users to interact with them before continuing. So, it is used to show important interaction information and non-continuous process information (for example, a sign-up or login form).
  • Non-modal dialogs allow users to interact outside the dialog box even if it is in an active state, which is suitable for frequent and nonblocking dialogs (for example, find-and-replace dialogs).

Dialog UI elements

The JavaScript dialog control provides necessary UI elements (header (title), body (content), and action area/footer) for better customization.


Action buttons

The JavaScript dialog control provides built-in support to perform actions through buttons, which define necessary callback functions to handle user input.


Positioning

Users can position a dialog wherever they want in a page. It is easy to configure this through built-in positions or any custom axis value (for example, top left, bottom right, top right, bottom left, 100 75, etc.).


Draggable

The modal dialog can be moved anywhere in a page by dragging its header, which is performed by using the Draggable library.


Overlays

Modal dialogs create overlays on open modal windows that provide options for a user to control the closing behavior of a dialog while interacting with it.

Additional dialogs

Users can launch multiple dialogs simultaneously or one above the other based on their z-index (z-depth) to make additional dialogs (nested modal dialogs).


Animation

A variety of smooth, built-in animations are available to configure for the opening and closing of modal dialogs. They perform based on CSS3 animation from the Animation library.


Resizable

The modal dialog can resize from any of the edges or borders of the dialog within the target container by using its handle (grip) or hovering on it.


Close options

The modal dialog can be closed by clicking on a close icon, with an overlay click, or by pressing the ESC key. Users can also restrict the closing behavior of a dialog based on its callback function parameters.


Remote content via AJAX

Users can directly load content from a remote source (for example, an external webpage) to a dialog using the AJAX library.


Alert and confirmation dialogs

Create JavaScript alerts and confirmation dialogs by using built-in functions.


Right-to-left (RTL)

The JavaScript dialog control supports right-to-left (RTL) rendering. Users can change the text direction and layout of the dialog control from right to left. This improves the user experience and accessibility for those who use RTL languages.


JavaScript Modal Dialog covers web accessibility

Accessibility

  • Fully supports WAI-ARIA accessibility, which helps dialogs be accessed by on-screen readers and assistive devices.

  • Follows WAI-ARIA Best Practices for implementing keyboard interaction.

  • The UI element visuals–such as foreground color, background color, line spacing, text, and images–were designed based on the WCAG 2.0 standard.

JavaScript Dialog works well in touch devices

Responsiveness

The JavaScript dialog control is highly configurable to make mobile dialogs and better user experiences across phone, tablet, and desktop form factors.


Themes

The JavaScript dialog control has several built-in themes such as Material, Bootstrap, Fabric (Office 365), Tailwind CSS, and High Contrast. Users can customize any one of these built-in themes or create new themes to achieve their own desired look and feel either by simply overriding SASS variables or using our Theme Studio application.

Developer-friendly APIs

Developers can control the appearance and behaviors of a dialog, including its positioning, content, and animation, using a rich set of APIs.


Other supported frameworks

The Modal Dialog component is also available in Blazor, React, Angular, and Vue frameworks. Check out the different Modal Dialog platforms from the links below,
