Node DOM Manipulation On The Page After A POST

Can i change the webpage the user is currently at after he forms a POST request? I am using Node serverside (maybe that is relevant). The problem is that i can only do one response

Solution 1:

I finally did this. You put both pages inside the one page. The two contents go to separate divs.

Then you use something like this code:

<script>
    document.querySelector('.div2').style.display = "none";
    document.querySelector('form').addEventListener("submit", function(e){
            document.querySelector('.div1').style.display = "none";
            document.querySelector('.div2').style.display = "block";
    });
</script>
