target =“ _ blank”的表单-新窗口和加载页面

Question

After submiting a form, a new page should open to be printed as pdf. But by doing it like that <form action="page.php" method="POST" target="_blank"> the form with all the information still exists which is very, very bad. Instead of still showing the page with the form, I would now like to load another page within this windows/tab AND open the print-window. With php and headers it's not possible, but with javascript should be right? But how? I'm not used to javascript, so I have no idea how to handle this problem, but do you have an idea?

Answer 1

You can attach an onsubmit event to the form, f.ex:

document.getElementById('form').onsubmit = function() {
    window.location = '/anotherpage.html';
}

This assumes that the form has an ID of "form".
