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 🙏

k-htmlpdf 是能将Dom一键配置输出pdf的包,

jspdf分页有个比较不好的地方就内容过长的时候虽然会虽然能做到分页,但是会把内容给截断,解决思路是给每个可能会被截断元素加上类,然后动态的计算该元素的位置是否在下一页和上一页之间,如果在的话就添加一个空白元素把这个元素给挤下去,这样就能实现了

1.安装依赖

    npm install c-htmlpdf

2.使用方法

    import PdfLoader from 'k-htmlpdf'

    let dom = document.querySelector("#pdfDom");
    let pdf = new PdfLoader(dom, "测试", "itemClass",'break_page');
    pdf.outPutPdfFn("测试");
  • 使用说明
 let pdf =  new PdfLoader(<ele>,<pdfFileName>,[width],[height],[orientation],[splitClassName],[breakClassName])
  • ele:需要导出pdf的容器元素(dom节点 不是id)
  • pdfFileName: 导出文件的名字 通过调用outPutPdfFn方法也可传参数改变
  • width: pdf宽度 默认为595
  • height: pdf高度 默认为842
  • orientation: pdf方向 默认为p,可选值为p和l,或者portrait和landscape
  • splitClassName: 避免分段截断的类名 当pdf有多页时需要传入此参数 , 避免pdf分页时截断元素 如表格
  • 调用方式 先 let pdf = new PdfLoader(ele, 'pdf' ,'itemClass');
  • 若想改变pdf名称 pdf.outPutPdfFn(fileName); outPutPdfFn方法返回一个promise 可以使用then方法处理pdf生成后的逻辑
  • breakClassName:自定义分页符类名,默认为break_page,添加改类名的标签被自动分页到下一页
  • 获取jsPDF实例
    pdf.genPdf(jsPDF=>{
        console.log(jsPDF)
    })
  • 输出下载pdf
 pdf.outPutPdfFn([fileName]) 
  • 预览pdf
    pdf.previewPdf()
  • 效果演示
  1. 正常效果
  2. 分页符
  3. 自动换页,防止切割
