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 🙏

Radar Analytics JS SDK:exposure 集成文档(2022.03.30)

元素曝光pv打点插件

本功能是基于radar-analytic-js-sdk的插件功能实现的。每次页面展示的元素,需要某个元素曝光后,获取元素属性的数据功能。该功能使用插件方式集成。集成步骤如下:

1、集成第三方库IntersectionObserver。w3c官方提供了polyfill,兼容了主流浏览器版本。

npm install intersection-observer --save-dev

2、集成插件

npm i radar-analytic-js-exposure

<script src="https://s3.ssl.qhres2.com/!a1ad9a60/radar-analytic-js-exposure.umd.js"></script>

3、初始化插件

var expose = RADAR_MONITOR.use('exposure', '');

expose是插件对象, 用来调用实例化方法。

4、注册曝光元素

expose.observe(element);

5、配置元素上报事件名称

设置自定义属性:bk-expose

事例如下:

<div class="container">
    <div id="bk1000" bk-expose="商品1">第一件商品</div>
    <div id="bk1000" bk-expose="商品2">第二件商品</div>
</div>
<div class="container" >
    <div>
        <div bk-expose="商品3">第三件商品</div>
        <div bk-expose="商品4">第四件商品</div>
    </div>
</div>

js-classname实现获取元素方式

var elements = document.getElementsByClassName('container');
console.log("注册元素:",elements);
for (const el in elements) {
    if (Object.hasOwnProperty.call(elements, el)) {
        const element = elements[el];
        expose.observe(element);
    }
}

或者使用document.getElementById来获取元素。
