# Progress Bar
|
|
|
|
[component-header:sl-progress-bar]
|
|
|
|
Progress bars are used to show the status of an ongoing operation.
|
|
|
|
```html preview
|
|
<sl-progress-bar value="50"></sl-progress-bar>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlProgressBar } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => <SlProgressBar value={50} />;
|
|
```
|
|
|
|
## Examples
|
|
|
|
### Custom Height
|
|
|
|
Use the `--height` custom property to set the progress bar's height.
|
|
|
|
```html preview
|
|
<sl-progress-bar value="50" style="--height: 6px;"></sl-progress-bar>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlProgressBar } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => <SlProgressBar value={50} style={{ '--height': '6px' }} />;
|
|
```
|
|
|
|
### Labels
|
|
|
|
Use the `label` attribute to label the progress bar and tell assistive devices how to announce it.
|
|
|
|
```html preview
|
|
<sl-progress-bar value="50" label="Upload progress"></sl-progress-bar>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlProgressBar } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => <SlProgressBar value="50" label="Upload progress" />;
|
|
```
|
|
|
|
### Showing Values
|
|
|
|
Use the default slot to show a value.
|
|
|
|
```html preview
|
|
<sl-progress-bar value="50" class="progress-bar-values">50%</sl-progress-bar>
|
|
|
|
<br />
|
|
|
|
<sl-button circle><sl-icon name="dash"></sl-icon></sl-button>
|
|
<sl-button circle><sl-icon name="plus"></sl-icon></sl-button>
|
|
|
|
<script>
|
|
const progressBar = document.querySelector('.progress-bar-values');
|
|
const subtractButton = progressBar.nextElementSibling.nextElementSibling;
|
|
const addButton = subtractButton.nextElementSibling;
|
|
|
|
addButton.addEventListener('click', () => {
|
|
const value = Math.min(100, progressBar.value + 10);
|
|
progressBar.value = value;
|
|
progressBar.textContent = `${value}%`;
|
|
});
|
|
|
|
subtractButton.addEventListener('click', () => {
|
|
const value = Math.max(0, progressBar.value - 10);
|
|
progressBar.value = value;
|
|
progressBar.textContent = `${value}%`;
|
|
});
|
|
</script>
|
|
```
|
|
|
|
```jsx react
|
|
import { useState } from 'react';
|
|
import { SlButton, SlIcon, SlProgressBar } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => {
|
|
const [value, setValue] = useState(50);
|
|
|
|
function adjustValue(amount) {
|
|
let newValue = value + amount;
|
|
if (newValue < 0) newValue = 0;
|
|
if (newValue > 100) newValue = 100;
|
|
setValue(newValue);
|
|
}
|
|
|
|
return (
|
|
<>
|
|
<SlProgressBar value={value}>{value}%</SlProgressBar>
|
|
|
|
<br />
|
|
|
|
<SlButton circle onClick={() => adjustValue(-10)}>
|
|
<SlIcon name="dash" />
|
|
</SlButton>
|
|
|
|
<SlButton circle onClick={() => adjustValue(10)}>
|
|
<SlIcon name="plus" />
|
|
</SlButton>
|
|
</>
|
|
);
|
|
};
|
|
```
|
|
|
|
### Indeterminate
|
|
|
|
The `indeterminate` attribute can be used to inform the user that the operation is pending, but its status cannot currently be determined. In this state, `value` is ignored and the label, if present, will not be shown.
|
|
|
|
```html preview
|
|
<sl-progress-bar indeterminate></sl-progress-bar>
|
|
```
|
|
|
|
```jsx react
|
|
import { SlProgressBar } from '@shoelace-style/shoelace/dist/react';
|
|
|
|
const App = () => <SlProgressBar indeterminate />;
|
|
```
