完成表单操作后如何自动重新加载页面

Question

I want to auto-reload the page after completion of the action of the form.

The code for my form is:

<form method="post" enctype="multipart/form-data" id="upload" action="<%=(String)request.getAttribute("base_url")%>files/upload/">

Answer 1

The browser will load whatever URL you specify in the action attribute.

If you want to reload the previous page then your server side code should output an HTTP redirect back to the previous page.

Location: http://example.com/page/with/form/on/it/

Answer 2

PHP Solution

Very simple solution with PHP

<?php
    if(isset($_POST['Submit']))
    {
    header("Location: http://yourpagehere.com");
    }
?>

Javascript Solution

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

Answer 3

Use the header() function.

To redirect to another page using this function, simply put in quotations

'Location: $desired_file'

• An example of a header function used to redirect to another page could be: header('Location: example.php'); .

For further instruction/help please see this link: http://php.net/manual/en/function.header.php

If you are trying to send data to a page using the action attribute, you WILL be redirected to that page. I'd like to help more but your question is not very clear.
