I wanted to convert my HTML page to a PDF file with a button click. After I click this "Download" button, I want the PDF to be automatically downloaded.

I tried this:

<button onclick="printFunction()">Download</button>
<script>
      function printFunction() { 
        window.print(); 
      }
</script>

But this can only generate a print page, which I need to save the PDF file manually.

I searched online and find a lot of answers that suggest we add a third-party plug-in. Is there an easier way to do that?

I found a similar example here: /download-html-page-as-pdf-using-javascript/

I'd use html2pdf

<body id="body">
<button id="button">Click me!</button>

<script src="html2pdf.bundle.min.js"></script>
<script>
const btn = document.getElementById("button");

btn.addEventListener("click", function(){
var element = document.getElementById('body');
html2pdf().from(element).save('filename.pdf');
});
</script>
</body>

here are the docs https://www.npmjs./package/html2pdf.js/v/0.9.0 You can change filename.pdf to whatever you want (aside from the extension)

This code worked for me:

<body id="body">

<script src="https://cdnjs.cloudflare./ajax/libs/html2pdf.js/0.10.1/html2pdf.bundle.min.js"></script>
<script>
    // Function to handle download
    function downloadFunction() {
        hideButtons();
        const element = document.getElementById('body');
        const formattedDate = new Date().toLocaleDateString('en-GB').replace(/\//g, '-');
        const options = {
            margin: 10,
            filename: 'FileName_' + formattedDate + '.pdf',
            image: { type: 'jpeg', quality: 1.0 },
            html2canvas: { scale: 4 },
            jsPDF: { unit: 'mm', format: 'a4', orientation: 'portrait' }
        };
        html2pdf(element, options);
        showButtons();
    }
</script>

<button onclick="downloadFunction()">Download this WebPage as PDF</button>
