Examples
Infinite Scroll
export default class extends React.Component {
constructor(props) {
super(props);
this.state = {
items: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20],
allowInfinite: true,
showPreloader: true,
};
}
render() {
return (
<Page
infinite
infiniteDistance={50}
infinitePreloader={this.state.showPreloader}
onInfinite={this.loadMore.bind(this)}
>
<Navbar title="Infinite Scroll"></Navbar>
<BlockTitle>Scroll bottom</BlockTitle>
<List>
{this.state.items.map((item, index) => (
<ListItem title={`Item ${item}`} key={index}></ListItem>
))}
</List>
</Page>
)
}
loadMore() {
const self = this;
if (!self.state.allowInfinite) return;
self.setState({ allowInfinite: false });
setTimeout(() => {
const items = self.state.items;
if (items.length >= 200) {
self.setState({ showPreloader: false });
return;
}
const itemsLength = items.length;
for (let i = 1; i <= 20; i += 1) {
items.push(itemsLength + i);
}
self.setState({
items,
allowInfinite: true,
});
}, 1000);
}
};
Pull To Refresh
export default class extends React.Component {
constructor(props) {
super(props);
this.state = {
items: [
{
title: 'Yellow Submarine',
author: 'Beatles',
cover: 'https://cdn.framework7.io/placeholder/abstract-88x88-1.jpg',
},
{
title: 'Don\'t Stop Me Now',
author: 'Queen',
cover: 'https://cdn.framework7.io/placeholder/abstract-88x88-2.jpg',
},
{
title: 'Billie Jean',

},
],
songs: ['Yellow Submarine', 'Don\'t Stop Me Now', 'Billie Jean', 'Californication'],
authors: ['Beatles', 'Queen', 'Michael Jackson', 'Red Hot Chili Peppers'],
}
}
render() {
return (
<Page ptr onPtrRefresh={this.loadMore.bind(this)}>
<Navbar title="Pull To Refresh"></Navbar>
<List mediaList>
{this.state.items.map((item, index) => (
<ListItem
key={index}
title={item.title}
subtitle={item.author}
>
<img slot="media" src={item.cover} width="44" />
</ListItem>
))}
<BlockFooter>
<p>Just pull page down to let the magic happen.<br />Note that pull-to-refresh feature is optimised for touch and native scrolling so it may not work on desktop browser.</p>
</BlockFooter>
</List>
</Page>
);
}
loadMore(event, done) {
const self = this;
setTimeout(() => {
const { items, songs, authors } = self.state;
const picURL = `https://cdn.framework7.io/placeholder/abstract-88x88-${(Math.floor(Math.random() * 10) + 1)}.jpg`;
const song = songs[Math.floor(Math.random() * songs.length)];
const author = authors[Math.floor(Math.random() * authors.length)];
items.push({
title: song,
author,
cover: picURL,
});
self.setState({ items });
done();
