We have crating pdf dynamically with the help of itextsharp.Now I want to show popup window on button click with the help of JavaScript fuction.How we can create this window in pdf.
You can use the window.open() method to create a popup in javascript, including a link in the url parameter, along with the name and any optional parameters.
<button class="popup" onclick="createPopup()"/>
function createPopup(url, name) {
let popup = open(url, name, 'width=500,height=500')
popup.focus();
}
You can then use window.opener() to return values from the popup to the parent.
Hope this helps.
