Javascript, Make a loop between 2 Pages and set a timer on 1-CodePudding

I want to create a while loop between 2 html page (Or a prompt where I can ask a question) and make so that if I give the wrong answer I get redirected to another HTML page that will remain for 5 seconds before getting back to the prompt.

I am trying the following code

<!DOCTYPE html>
<html>
<body>
    <script>
        var pass;
            pass = prompt("The corret answer is 1");
        if (pass == "1") {
            document.location.href = "https://stackoverflow.com/questions/40539097/redirect-user-to-another-html-page-if-the-condition-is-true";
        } else {
            setTimeout(function(){
              window.location.href = 'prova2.html';
         }, 5000);
        }
</script>
    <body>
</html>

The Problem is that the page "prova2.html" came out after 5 second. Instead I want that it remain visible for 5 seconds.

CodePudding user response：

But that's exactly what your code does: if the result of prompt is '1' it redirects to SO, otherwise you start a timer that redirects to prova2 after 5 seconds.

If you want the behaviour you're describing, you need to redirect to prova2.html immediately and in the code for prova2.html you need to set a timeout that redirects you back after 5 seconds:

in original.html (or whatever it's called for you):

<!DOCTYPE html>
<html>
  <body>
    <script>
      var pass = prompt("The corret answer is 1");
      if (pass == "1") {
        document.location.href = "https://stackoverflow.com/questions/40539097/redirect-user-to-another-html-page-if-the-condition-is-true";
      } else {
        document.location.href = 'prova2.html';
      }
    </script>
  <body>
</html>

in prova2.html:

<!DOCTYPE html>
<html>
  <body>
    <script>
      setTimeout(() => {
        document.location.href = 'original.html';
      }, 5000)
    </script>
  <body>
</html>

CodePudding user response：

This example of prova2.html does not rely on filenames, it uses the session history of the browser:

<!DOCTYPE html>
<html>
<body>
    <script>
      document.addEventListener("DOMContentLoaded", function(event) {
        setTimeout(function(){
            history.back();
            //window.location.href = 'previous.html';
          }, 5000);
        });
    </script>
      <p>5 sec after pageload you should get redirected back</p>
    <body>
</html>
