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 🙏

Demo

请打开控制台

https://q-jason.github.io/across-nodes-search-keywords/docs/

安装

npm i --save across-nodes-search-keywords

or

<script src="./dist/across-nodes-search-keywords.js"></script>

使用

var result = window.acrossNodesSearchKeywords({
  el: document.querySelector('body'),
  keywords: 'any text'
})

/**
 result 解析
 {
    // el 元素下的所有文本内容
    "fullText": "巴拉巴拉",
    // 搜索的关键词
    "keywords": "巴拉巴拉",
    // 匹配到的结果
    "matchResults": [
        // 代表一条匹配到的关键词数据
        {
            // 关键词出现的开始位置
            "startIndex": 266,
            // 关键词出现的结束位置
            "endIndex": 601,
            // 已经被 splitText 处理后的 nodeText 节点
            "textNodes": [
                {},
                {}
            ]
        }
    ]
}
 **/

注意

方法本身仅用 splitText 方法切分 nodeText 节点,并返回响应数据,除此之外不做任何其他处理 需要高亮等逻辑需手动处理,如下:

result.matchResults.forEach(function (item) {
  item.textNodes.forEach(function (node) {
    var font = document.createElement('font')
    font.innerHTML = node.textContent
    node.parentNode.replaceChild(font, node)
  })
})
