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 🙏

Readme

tingle-load-more npm version

Load-more 是下拉加载更多插件。只控制「加载更多」状态条的显示隐藏,通知父元素进行加载。

Simple Usage

constructor(props) {
    super(props);
    this.state = {
        data: [],
        page: 1
    }
}


componentDidMount() {
    // 默认需要直接先初始化一次
    this.startLoad();
}

startLoad() {
    const t = this;
    let loadMore = t.refs.loadMore;

    // 告诉 LoadMore 开始加载了,LoadMore 会显示正在加载中
    loadMore.loading();

    $.getJSON(URL, {page: t.state.page}, function (d) {
        if (d.success) {
            let data = t.state.data.concat(d.data);
            t.setState({data: data, page: ++t.state.page});
            if(d.hasMore){
                // 告诉 LoadMore 加载完成 , 如果不告知 LoadMore 已经加载完成,LoadMore 不会再监听下一次的 inViewPort 事件
                loadMore.loaded();
            }else{
                // 告诉 LoadMore 已经没有更多了,LoadMore 会显示没有更多。
                loadMore.noMore();
            }
        }
    })
}

render() {
    return (
        <div>
            {this.state.data.map(function (d) {
                return (<p key={Context.getTID()} className="tDemoP tFAC">{d}</p>);
            })}
            <LoadMore className="tFAC" offset={50} onLoadMore={this.startLoad.bind(this)} ref='loadMore'>
            </LoadMore>
        </div>
    );
}

可用配置

| 配置项 | 必填 | 默认值 | 功能/备注 | |---|----|---|----| |offset|optional|50| 数据(注1)| |onLoadMore|required|Tingle.noop()| 触发加载之后的调用函数 (注2) | |loadingText|optional|正在加载中…| 加载中的文案 | |noMoreText|optional|没有啦!| 没有更多的文案 |

注1: offset 的 最小取值为 50 ,当传入的值小于 50 时,会自动传入 50 ,用以修复在某些 Android 机型上的兼容性问题。

注2: 每次当用户滑动到需要加载的位置时,load-more 会通知父级元素去加载数据,也就是通过这个函数传递。

API接口

.loading()

加载锁,防止重复触发 onLoadMore 事件。

.loaded()

changed in 0.2.1 : 如果不满一屏,loaded 执行自后会自动再次触发加载。

加载完成时调用的函数。

.noMore()

没有更多了。
