| description | Implement and configure the Syncfusion EJ2 JavaScript Buttons components (ProgressButton, RadioButton, and SplitButton). Use this when adding interactive button controls, progress indicators, radio selections, or dual-action menus in a JavaScript or ES5 application. This skill covers component configuration, states, events, templates, accessibility, and common UI patterns. |

Syncfusion JavaScript Buttons
ProgressButton
The Syncfusion EJ2 JavaScript ProgressButton visualizes the progression of an operation, indicating to the user that a background process is running. It supports a background filler UI, spinner customization, content animation, progress events, and programmatic start/stop control.
Navigation Guide
Getting Started
📄 Read: references/getting-started.md
- Install
@syncfusion/ej2-splitbuttons and set up dependencies
- Initialize ProgressButton with
new ProgressButton({...})
- TypeScript setup via webpack quickstart
- Add CSS/theme references (local and CDN)
- Enable the background filler with
enableProgress: true
- Minimal working ES5 and TypeScript examples
Spinner and Progress
📄 Read: references/spinner-and-progress.md
- Change spinner position (
spinSettings.position: Left/Right/Top/Bottom/Center)
- Change spinner size (
spinSettings.width)
- Use a custom spinner template (
spinSettings.template)
- Animate button content during progress (
animationSettings.effect, duration, easing)
- Control progress step intervals via
ProgressEventArgs.step in the begin event
- Dynamically change progress percentage via
ProgressEventArgs.percent
- Start and stop progress programmatically with
start() and stop() methods
Events
📄 Read: references/events.md
begin — fires when progress starts, use to set initial stateprogress — fires at each step interval, use to update UIend — fires when progress completes, use to reset or show successfail — fires when progress is incompletecreated — fires after the component renders- Tracing all events and logging pattern
How-To Patterns
📄 Read: references/how-to.md
- Hide the spinner using
e-hide-spinner CSS class
- Change text content and styles of the button during progress
- Customize progress direction: vertical (
e-vertical), top (e-progress-top), reverse
- Use
dataBind() to apply property changes immediately
Accessibility
📄 Read: references/accessibility.md
- WCAG 2.2 and Section 508 compliance
- WAI-ARIA attributes (
aria-label, aria-disabled)
- Keyboard navigation (
Enter / Space to start progress)
- Screen reader, RTL, and mobile device support
API Reference
📄 Read: references/api.md
- All properties with types and defaults
SpinSettingsModel interface (position, template, width)AnimationSettingsModel interface (effect, duration, easing)ProgressEventArgs interface (percent, step, currentDuration, name)- All methods:
start(), stop(), dataBind(), progressComplete(), destroy()
- All events:
begin, progress, end, fail, created

Common Patterns
Download button with pause/resume
import { ProgressButton } from '@syncfusion/ej2-splitbuttons';
const progressBtn: ProgressButton = new ProgressButton({
content: 'Download',
enableProgress: true,
duration: 4000,
iconCss: 'e-btn-sb-icon e-download',
cssClass: 'e-hide-spinner',
end: (): void => {
progressBtn.content = 'Download';
progressBtn.iconCss = 'e-btn-sb-icon e-download';
progressBtn.dataBind();
}
});
progressBtn.appendTo('#progressbtn');
progressBtn.element.addEventListener('click', (): void => {
if (progressBtn.content === 'Download') {
progressBtn.content = 'Pause';
progressBtn.iconCss = 'e-btn-sb-icon e-pause';
progressBtn.dataBind();
} else if (progressBtn.content === 'Pause') {
progressBtn.content = 'Resume';
progressBtn.iconCss = 'e-btn-sb-icon e-play';
progressBtn.dataBind();
progressBtn.stop();
} else if (progressBtn.content === 'Resume') {
progressBtn.content = 'Pause';
progressBtn.iconCss = 'e-btn-sb-icon e-pause';
progressBtn.dataBind();
progressBtn.start();
}
});
Upload button with text state changes
import { ProgressButton } from '@syncfusion/ej2-splitbuttons';
const uploadBtn: ProgressButton = new ProgressButton({
content: 'Upload',
cssClass: 'e-hide-spinner',
enableProgress: true,
duration: 4000,
begin: (): void => {
uploadBtn.content = 'Uploading...';
uploadBtn.cssClass = 'e-hide-spinner e-info';
uploadBtn.dataBind();
},
end: (): void => {
uploadBtn.content = 'Success';
uploadBtn.cssClass = 'e-hide-spinner e-success';
uploadBtn.dataBind();
setTimeout((): void => {
uploadBtn.content = 'Upload';
uploadBtn.cssClass = 'e-hide-spinner';
uploadBtn.dataBind();
}, 500);
}
});
uploadBtn.appendTo('#progressbtn');
Spinner on the right with custom size
import { ProgressButton } from '@syncfusion/ej2-splitbuttons';
const progressBtn: ProgressButton = new ProgressButton({
content: 'Submit',
spinSettings: { position: 'Right', width: 20 }
});
progressBtn.appendTo('#progressbtn');
RadioButton
The Syncfusion EJ2 JavaScript RadioButton is a graphical UI element that lets a user select exactly one option from a group. It supports checked/unchecked states, label positioning, small size, disabled state, RTL layout, form integration via name/value, custom CSS appearance, full keyboard navigation, and WCAG 2.2 accessibility — all from the @syncfusion/ej2-buttons package.

Common Patterns
RadioButton group with change event
import { RadioButton, ChangeEventArgs } from '@syncfusion/ej2-buttons';
let rb1: RadioButton = new RadioButton({
label: 'Option 1',
name: 'group',
checked: true,
change: (args: ChangeEventArgs) => {
console.log('Selected: ' + (args.event.target as HTMLInputElement).value);
}
});
rb1.appendTo('#element1');
Small-size RadioButton
import { RadioButton } from '@syncfusion/ej2-buttons';
let rb: RadioButton = new RadioButton({ label: 'Small', name: 'size', cssClass: 'e-small' });
rb.appendTo('#element');
Disabled RadioButton
import { RadioButton } from '@syncfusion/ej2-buttons';
let rb: RadioButton = new RadioButton({ label: 'Disabled Option', name: 'group', disabled: true });
rb.appendTo('#element');
SplitButton
The Syncfusion EJ2 JavaScript SplitButton renders a dual-action button: the primary button triggers a default action, and the secondary arrow button opens a contextual popup menu with additional action items. It supports icons, separators, item/popup templating, RTL, disabled state, keyboard navigation, and full accessibility — all from the ej2-splitbuttons package.
