How Can I Refresh A Form Page After The Form Submits To _blank?

I have an HTML form which targets _blank. I would like the page that form is on to reload after submitting. So here's some sample markup:

Solution 1:

Not sure why window.location.reload() doesn't work. I think it should. However, this does seem to work:

onsubmit="setTimeout(function () { window.location.reload(); }, 10)"

Solution 2:

There are two ways to do this, one that you may not want to hear about.

FIRST:

In the form init tag, if you set action="" then the form will submit to the same page (to itself).

<form action="" method="post">

This allows you to add server-side code to the top of the page, like this (using PHP, for example):

<?php
    If (empty($_POST)===false) {
        //server side scripting to handle the submitted form
    }else{
?>
    //HTML to create/show the page with form for user input
<?php
    //Close the if statement
    }
?>

SECOND:

Use AJAX (javascript or jQuery) to "submit" the form, and then -- in the AJAX function's callback -- carry on with whatever changes you want to make to the page, including redirecting to a new page.

Solution 3:

It should work if a callback is passed to the onsubmit event attribute. For example,

(Traditional anonymous function)

onsubmit="function() {location.reload()}"

or

(Arrow function)

onsubmit="() => location.reload()"

Solution 4:

location.refresh(true);

will help
