JavaScript Guide: The Basics of HTML to PDF

It is no secret that JavaScript has plenty of different uses that you can take advantage of. In fact, many people use their knowledge of JavaScript as the foundation for their entire careers.

However, you don’t need to be an expert with this programming language in order to make use of it. The below JavaScript guide has everything that you need to know about converting from HTML to PDF format.

Implement the jsPDF Library and jQuery

In order to get started with your HTML to PDF conversion, you’ll need to take the above action. For beginners, this might sound like a complicated process.

In reality, however, it’s as simple as including a few key lines of code. This information is as follows:

<script src=”js/jquery.min.js”></script>

<script src=”js/jsPDF/dist/jspdf.min.js”></script>

These two lines load jQuery and the jsPDF Library respectively. It’s also important to note that you don’t need to download the jsPDF library separately, something that helps streamline the process.

Instantiate a jsPDF Class

The following line of code will allow you to instantiate a jsPDF object for use in JavaScript:

var doc = new jsPDF();

This essentially “activates” the above class so you can use it as a tool. Without this step, you won’t be able to properly convert HTML format to PDF format.

Generate a PDF File With JavaScript

After the class has been implemented, you can begin to use JavaScript itself to generate a PDF file.

First, you’ll want to specify the HTML content with the text() method of the jsPDF object. This will tell the program what text to import to the PDF file.

You can use the addPage() method to add an additional page to the PDF. When you are finished with this process, you can use the save() method to generate the PDF file and then download it.

What Does It Look Like in Context?

If you’re having trouble visualizing what your JavaScript code should look like, we’ve included an example below. The following code is what you would typically find during your average HTML to PDF conversion:

var doc = new jsPDF();

var elementHTML = $(‘#contnet’).html();

var specialElementHandlers = {

‘#elementH’: function (element, renderer) {

     return true;

}

};

doc.fromHTML(elementHTML, 20, 20, {

‘width’: 190,

‘elementHandlers’: specialElementHandlers

});

 

doc.save(‘sample-document.pdf’);
