使用指南

import Watcher from 'mor-scroll-watcher'
const WatcherItem = Watcher.item

Watcher.init(options)
<WatcherItem ...>
	...
</WatcherItem>

你只需要将需要被滚动触发的节点设置为WatcherItem节点的children，就能达到滚动触发的目的。

代码演示

import React, { Component } from 'react'
import Watcher from 'mor-scroll-watcher'

const WatcherItem = Watcher.item

export default class Home extends Component {
	componentDidMount () {
		new Watcher({
			wrap: findDOMNode(this.refs.views)
			// bottomEmit: 100,
			// initEmit: false
		})
	}

	onWatcher (index) {
		// do something
		console.log(index)
	}

	render () {
		const list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
		return (
			<div className="wrap" ref="views">
				<For of={list} each="item" index="index">
					<WatcherItem
						className="w-full scroller-item"
						key={index}
						style={{
							height: '200px',
							background: 'yellow',
							margin: '20px 0'
						}}
						onWatcher={this.onWatcher.bind(this, index)}
					>
						{item}
					</WatcherItem>
				</For>
			</div>
		)
	}
}

高阶用法

当页面内存在多个需要被监听滚动的容器时，需要设置唯一ID

import React, { Component } from 'react'
import Watcher from 'mor-scroll-watcher'

const WatcherItem = Watcher.item

export default class Home extends Component {
	componentDidMount () {
		new Watcher({
			wrap: findDOMNode(this.refs.views)
			monaId: 'weiyiID_123456'
			// bottomEmit: 100,
			// initEmit: false
		})
	}

	onWatcher (index) {
		// do something
		console.log(index)
	}

	render () {
		const list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
		return (
			<div className="wrap" ref="views">
				<For of={list} each="item" index="index">
					<WatcherItem
						monaId: 'weiyiID_123456'
						className="w-full scroller-item"
						key={index}
						style={{
							height: '200px',
							background: 'yellow',
							margin: '20px 0'
						}}
						onWatcher={this.onWatcher.bind(this, index)}
					>
						{item}
					</WatcherItem>
				</For>
			</div>
		)
	}
}
