Conclusion

♣️ I decide to write the whole code in index.html, feel free to refactor it to your convenience. The invoice template is gotten from Bootsnip written by heidilux. I made a little tweaking to the template to tailor it to this project.

🎯 First of all, add the html2pdf CDN script to the head of your HTML boilerplate.

🎯 Also, add this to the head

<link href="//netdna.bootstrapcdn.com/bootstrap/3.1.0/css/bootstrap.min.css" rel="stylesheet" id="bootstrap-css">
<script src="//netdna.bootstrapcdn.com/bootstrap/3.1.0/js/bootstrap.min.js"></script>
<script src="//code.jquery.com/jquery-1.11.1.min.js"></script>

🎯 Next, Let's flesh out our div container in index.html that holds all the data contained in the invoice.
📝 Ensure you wrap the content to display in the div.

🎯 We write our button onclick event

<button onclick="generatePDF()">Generate Invoice</button>

🎯 Lastly, we write our JavaScript function.

<script>
    function generatePDF() {
        const element = document.getElementById('invoice');
        html2pdf()
            .from(element)
            .save();

    }
</script>

Click on the Generate Invoice button to test.
