I have a problem with a PHP page that uses TCPDF.
Everything works fine, but after the Output command I need to ask the user if he wants to repeat the calculation or change the data to be processed.
To do this I add some HTML tags
echo "<p>Click to confirm or choose other data to repeat the calculation.</p>";
echo "<button onclick='myFunction()'>Confirm</button>";
echo "<p id='response'></p>";
myFunction is a javascript function:
function myFunction() {
let text = "Press the button!nYes to confirm or nCancel to perform another calculation.";
if (confirm(text) == true) {
text = "The calculation is no longer available!";
setTimeout(window.history.go(-2),30000);
} else {
text = "You Canceled! You will be redirected to the page for another calculation!";
setTimeout(window.history.go(-1),30000);
}
document.getElementById("response").innerHTML = text;
}
The HTML code and no message are displayed.
I wrote a test page without TCPDF and everything works fine.
Where am I going wrong? o What doesn’t TCPDF like?
Thanks for the help
Andrea
I hope to find out where I’m going wrong.
This is the test page.

<html>
<head>
<script>
function myFunction() {
let text = "Premi il bottone!n Sì per confermare o nAnnulla per eseguire un altro calcolo.";
if (confirm(text) == true) {
text = "La ricevuta non è più modificabile!";
setTimeout(window.history.go(-2),30000);
} else {
text = "Hai Anullato! Verrai indirizzato alla pagina per un altro calcolo!";
setTimeout(window.history.go(-1),30000);
}
document.getElementById("risposta").innerHTML = text;
}
</script>
