How Can I Generate a PDF from an HTML Div Using JavaScript and jsPDF?
Generate PDF from HTML in Div Using JavaScript
Problem
You have HTML code containing a div with an id of "pdf" that you want to print to a PDF file named "foobar.pdf" using JavaScript. However, jspdf only accepts string values and does not have a function to print HTML.
Solution
To enable jsPDF to print HTML, you need to include the following plugins in your project:
- jspdf.plugin.from_html.js
- jspdf.plugin.split_text_to_size.js
- jspdf.plugin.standard_fonts_metrics.js
Additionally, if you want to ignore certain elements in the HTML, you can mark them with an ID and then use a special element handler in jsPDF to exclude those elements from printing. For example, the updated HTML code with an ignored element:
<!DOCTYPE html>
<html>
<body>
<p>JavaScript Code
This JavaScript code will generate a PDF with the content of the "pdf" div and open it in a new window:
var doc = new jsPDF();
var elementHandler = {
'#ignorePDF': function (element, renderer) {
return true;
}
};
var source = window.document.getElementsByTagName("body")[0];
doc.fromHTML(source, 15, 15, {
'width': 180,
'elementHandlers': elementHandler
});
doc.output("dataurlnewwindow");Notes
- You can only use element IDs for exclusion in element handlers. Class selectors are not supported.
- jsPDF ignores CSS styles, but it can format headings (h1, h2, etc.) and text within text nodes. Elements like textareas are not supported for printing.

Demystifying JavaScript: What It Does and Why It Matters
Apr 09, 2025 am 12:07 AM
JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
The Evolution of JavaScript: Current Trends and Future Prospects
Apr 10, 2025 am 09:33 AM
The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.
JavaScript Engines: Comparing Implementations
Apr 13, 2025 am 12:05 AM
Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.
JavaScript: Exploring the Versatility of a Web Language
Apr 11, 2025 am 12:01 AM
JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.
Python vs. JavaScript: The Learning Curve and Ease of Use
Apr 16, 2025 am 12:12 AM
Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

From C/C to JavaScript: How It All Works
Apr 14, 2025 am 12:05 AM
The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.
