Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

2. 完整例子

import React from 'react';
import Luo from 'iscroll-luo';

class Test extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
    	data: [1, 2, 3], // 初始数据
	};
  }

  /** 下拉刷新 **/
  onDown() {
  	this.setState({
  		data: [1, 2, 3], // 覆盖原始数据
  	});
	/** 注意此处,就算没有数据或接口调用失败了等情况,也要刷一下原始数据,Luo内部才知道状态更新了 **/
  }

  /** 上拉加载更多 **/
  onUp() {
  	this.setState({
  		data: [...this.state.data, 1, 2, 3], // 在原始数据后面加更多数据
  	});
	/** 注意此处,就算没有更多数据了或接口调用失败了等情况,也要刷一下原始数据,Luo内部才知道状态更新了 **/
  }

  render() {
  	return (
		{/** 务必用一个具有高度的容器包裹iscroll-luo组件 **/}
  		<div style={{ position: 'relative', height: '100vh' }}>
  			<Luo
  				id='id'
  				onDown={() => this.onDown()}
            			onUp={() => this.onUp()}
  			>
  				{
	  				this.state.data.map((v, i) =>
	  					<div key={i}>{v}</div>
	  				)
  				}						
  			</Luo>
  		</div>
  	);
  }
}

noUp					# 可选 bool     是否关闭上拉加载 默认false

noUpStr					# 可选 string   关闭上拉加载后,上拉区域显示的文字 默认无
className				# 可选 string	额外的class,会添加到iscroll-luo组件的包裹元素上
detectionHeight       			# 可选 bool 	是否自动检测容器高度变化 默认false
iscrollOptions: {			# 可选 object	iscroll的原生参数,初始化时会作为iscroll的options

	pulldownReadyInfo: '松开刷新',	# 触发下拉刷新的文字
	pulldowningInfo: '刷新中…',	# 正在刷新中的文字
	pullupInfo: '加载更多',		# 上拉加载的文字
	pullupReadyInfo: '松开加载',	# 触发上拉加载的文字
	pullupingInfo: '加载中…',	# 正在加载中的文字
}

4. 特性

  • 传入iscroll-luo中的数据改变时,即this.props.children改变时,iscroll-luo认为已经成功刷新或成功加载更多了,iscroll-luo会刷新内部状态
  • 参数detectionHeight,设为true后,iscroll-luo会不停的检测容器的高度是否变化,如果变化了,则自动调用iscroll的refresh()方法一般不需要开这个,除非有手动改变高度的需求。window的大小改变、手机的横屏竖屏切换,会自动刷新
  • this.props.children、this.props.noDown(关闭下拉)、this.props.noUp(关闭上拉) 这几个属性的值被改变时,都会刷新Luo内部的状态
