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 🙏

preact-dom-delegate

A preact plugin for DOM events delegate

Readme

preact-dom-delegate

NPM Version NPM Downloads

实现 preact 的 dom 事件委托

只支持 preact 8,Preact X 可以使用 preact-event-delegate

安装

$ npm i -S preact-dom-delegate

使用说明

在 JSX DOM 上设置 on 属性,值为委托处理方法,该方法会传入一个委托对象 delegate,仿照 jQuery 写法,使用 delegate.on(events, selector, handler) 方法就可以进行事件委托。

在事件处理函数中执行 return false,可以阻止该节点后续事件委托的执行,同时会停止事件冒泡。

支持的事件

参照 React 说明,https://reactjs.org/docs/events.html#supported-events,理论上可以对所有支持冒泡的事件进行委托。

事件名采用驼峰形式,如 touchstart 事件要用 touchStart 进行委托。

调用示例

// index.js
import 'preact-dom-delegate';

class App extends Component {
    render() {
        return (
            <article
                on={delegate =>
                    delegate
                        .on('click', '.btn', function(e) {
                            console.log('click .btn', this, e);
                        })
                        .on('touchStart', '.wrap', function(e) {
                            console.log('touchStart .wrap', this, e);
                            return false;
                        })
                        .on('touchMove', '.wrap', function(e) {
                            console.log('touchMove .wrap', this, e);
                        })
                        .on('touchEnd', '.wrap', function(e) {
                            console.log('touchEnd .wrap', this, e);
                        })
                        .on('click', 'header', function(e) {
                            console.log('click header', this, e);
                            return false;
                        })
                        .on('click', function(e) {
                            console.log('click this', this, e);
                        })
                }
            >
                <header>preact-dom-delegate</header>
                <section class="wrap">
                    <button class="btn">按钮</button>
                </section>
                <footer>
                    <a href="https://github.com/xingqiao">@xingqiao</a>
                </footer>
            </article>
        );
    }
}
