# Pagination >> Use Cases ||20
|
|
|
|
```js script
|
|
import { html } from '@mdjs/mdjs-preview';
|
|
import '@lion/ui/define/lion-pagination.js';
|
|
```
|
|
|
|
## Without current defined
|
|
|
|
```js preview-story
|
|
export const withoutCurrentPage = () => {
|
|
return html` <lion-pagination count="20"></lion-pagination> `;
|
|
};
|
|
```
|
|
|
|
## Ensure a count value
|
|
|
|
Be sure to set a count value or you will get an "empty" pagination.
|
|
|
|
```js preview-story
|
|
export const ensureCount = () => {
|
|
return html` <lion-pagination></lion-pagination> `;
|
|
};
|
|
```
|
|
|
|
### Methods
|
|
|
|
There are the following methods available to control the pagination.
|
|
|
|
- `next()`: move forward in pagination
|
|
- `previous()`: goes back to pagination
|
|
- `first()`: to the first page
|
|
- `last()`: to the last page
|
|
- `goto(pageNumber)`: to the specific page
|
|
|
|
```js preview-story
|
|
export const methods = ({ shadowRoot }) => {
|
|
setTimeout(() => {
|
|
shadowRoot.getElementById('pagination-method-demo').innerText =
|
|
shadowRoot.getElementById('pagination-method').current;
|
|
});
|
|
|
|
return html`
|
|
<p>The current page is: <span id="pagination-method-demo"></span></p>
|
|
<lion-pagination
|
|
id="pagination-method"
|
|
count="100"
|
|
current="75"
|
|
@current-changed=${e => {
|
|
const paginationState = shadowRoot.getElementById('pagination-method-demo');
|
|
paginationState.innerText = e.target.current;
|
|
}}
|
|
></lion-pagination>
|
|
<section style="margin-top:16px">
|
|
<button @click=${() => shadowRoot.getElementById('pagination-method').previous()}>
|
|
Previous
|
|
</button>
|
|
<button @click=${() => shadowRoot.getElementById('pagination-method').next()}>Next</button>
|
|
<br />
|
|
<br />
|
|
<button @click=${() => shadowRoot.getElementById('pagination-method').first()}>First</button>
|
|
<button @click=${() => shadowRoot.getElementById('pagination-method').last()}>Last</button>
|
|
<br />
|
|
<br />
|
|
<button @click=${() => shadowRoot.getElementById('pagination-method').goto(55)}>
|
|
Go to 55
|
|
</button>
|
|
</section>
|
|
`;
|
|
};
|
|
```
|
|
|
|
### Event
|
|
|
|
`lion-pagination` fires an event on button click to notify the component's current state. It is useful for analytics purposes or to perform some actions on page change.
|
|
|
|
- `@current-changed`: triggers when the current page is changed
|
|
|
|
```js preview-story
|
|
export const event = ({ shadowRoot }) => {
|
|
setTimeout(() => {
|
|
shadowRoot.getElementById('pagination-event-demo-text').innerText =
|
|
shadowRoot.getElementById('pagination-event-demo').current;
|
|
});
|
|
|
|
return html`
|
|
<p>The current page is: <span id="pagination-event-demo-text"></span></p>
|
|
<lion-pagination
|
|
id="pagination-event-demo"
|
|
count="10"
|
|
current="5"
|
|
@current-changed=${e => {
|
|
const paginationState = shadowRoot.getElementById('pagination-event-demo-text');
|
|
paginationState.innerText = e.target.current;
|
|
}}
|
|
></lion-pagination>
|
|
`;
|
|
};
|
|
```
