Printing PDF using JavaScript

For printing the PDF using JS we need to use the following code. In which we have used a input tag and onClick of that input we have called the div id which we want to print.

<div id="printContent">
Lorem ipsum dolor sit, amet consectetur adipisicing elit. Cum quisquam
esse natus error beatae tempore perspiciatis maxime, doloremque dicta quo
obcaecati officia amet. Reiciendis necessitatibus qui voluptatem excepturi
mollitia provident at hic quia earum, architecto odio quidem doloremque
atque officia porro.

value="Click me to get the PDF!"

function printDiv(divName) {
var printContents = document.getElementById(divName).innerHTML;
var originalContents = document.body.innerHTML;
document.body.innerHTML = printContents;
document.body.innerHTML = originalContents;

Hide a div from printing a webpage using CSS

@media print {
.noprint *
display: none !important;
height: 0;

We can also use :
1. [ visibility: hidden; ]
2. Bootstrap 5 class : [ .d-print-none ]
3. If you don't want to use CSS you can use show/hide with JavaScript.


Appending a div to the body of a webpage using JavaScript

"<div style='position:absolute;width:100%;height:100%;z-index:1000;top:0;left:0;'></div>"

Use Case : When we want to disable something at the time of AJAX Call.
