jsPDF Tutorial to Draw Colored & Filled Rectangle and Write Some Text Over It in PDF Document Using Javascript

Welcome folks today in this blog post we will be drawing a colored and filled rectangle and write some text over it in pdf document using jspdf in javascript. All the full source code of the application is shown below.

Get Started

In order to get started you need to make an index.html file and copy paste the following code

index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Document</title>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.5.3/jspdf.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf-autotable/3.2.3/jspdf.plugin.autotable.min.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/1.4.1/html2canvas.min.js"></script>
  </head>
  <body>
 
  </body>
</html>

<!DOCTYPE html>

<head>

<title>Document</title>

</head>

<body>

</body>

</html>

And now inside the html5 code we are including the jspdf library cdn and also we are including the html2canvas library cdn. And now we need to write the html code as shown below

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

1	<button onclick="generatePDF()">Generate PDF</button>

Now as you can see we have added a button which is used to generate the pdf document. Now we have added the onclick event listener which is the method called generatePDF() now we need to define this method in javascript.

function generatePDF() {
   
        
          var doc = new jsPDF();
   
  doc.setFontSize(17);
   
  doc.setFillColor(0,0,0);
  doc.rect(100, 20, 60, 10, 'F');
   
  doc.setTextColor(255, 255, 255);
  doc.text(100,28, 'USD.00');
   
          doc.save("output.pdf")
      }
   
      </script>

function generatePDF() {

var doc = new jsPDF();

doc.setFontSize(17);

doc.setFillColor(0,0,0);

doc.rect(100, 20, 60, 10, 'F');

doc.setTextColor(255, 255, 255);

doc.text(100,28, 'USD.00');

doc.save("output.pdf")

}

</script>

As you can see we are using the methods to set the font size and the background fill color and then we are drawing the rectangle shape inside the pdf document and then inside it we are writing the text which is usd inside it. And then we are saving the pdf document using the save() method
