Generate PDFs from HTML Divs Using JavaScript
<p>
Problem:
<p>Converting HTML content within a specific div element to a PDF using JavaScript. The generated PDF should automatically download with a preferred file name.
<p>
Solution Using jsPDF with Plugins:
-
<p>Include the following jsPDF plugins:
- jspdf.plugin.from_html.js
- jspdf.plugin.split_text_to_size.js
- jspdf.plugin.standard_fonts_metrics.js
-
<p>Ignore unwanted HTML elements by assigning them an ID and excluding them in the jsPDF element handler:
-
<p>Use doc.fromHTML to convert the HTML content to PDF:
var doc = new jsPDF();
var source = window.document.getElementsByTagName("body")[0];
doc.fromHTML(source, 15, 15, { width: 180, elementHandlers: elementHandler });
Copy after login
-
<p>Automatically open the PDF in a new window:
doc.output("dataurlnewwindow");
Copy after login
<p>
Additional Notes:
- Custom element handlers can only match elements with IDs.
- jsPDF loses CSS styles during conversion, but supports formatting of headings (h1, h2, etc.).
- Only text within text nodes will be printed, not the values of textareas or similar input fields.
