This article will give you a detailed explanation on how to generate PDF. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

1. Generate PDF at the backend

Thinkphp uses the MPDF plug-in

Sample code:

Public function pdf () {

/ / introduce the class library

Vendor ('mpdf.mpdf')

/ / set Chinese coding

$mpdf=new\ mPDF ('zh-cn','A4', 0,' Song style', 0,0)

/ / html content

$html=' a PDF file'

$mpdf- > WriteHTML ($html)

$mpdf- > Output ()

Exit

}

two。 Use the command line to link web pages to generate PDF

Download wkhtmltox

Tool command link generated PDF file

. / wkhtmltox/bin/wkhtmltopdf http://www.baidu.com test.pdf

3. Using js to generate PDF

Introduce the following two js plug-ins

Html2canvas.js

Jspdf.debug.js

Sample code:

Function explode () {

$(".ncap-order-details") .css ("background-color",'# FFFFFF')

Html2canvas ($(".ncap-order-details"), {

Onrendered:function (canvas) {

Var pageData = canvas.toDataURL (1. 0)

Var pdf = new jsPDF ('', 'pt', 'a4')

Pdf.addImage (pageData, 'JPEG', 0, 0, 595.28, 592.28/canvas.width * canvas.height)

Pdf.save ('stone.pdf')

}

})

}

Principle: first take screenshots, then insert screenshots into PDF

$(".ncap-order-details") is the div area to be screenshot. The screenshot defaults to a transparent background, so set the background color in advance, and then save the screenshot to PDF.
