警报框陷入无限循环

Question

I have an alert box which is supposed to refresh the page when the user clicks OK. Instead of this happening, the alert box disappears and then reappears when the user clicks OK.

It's stuck in an endless loop of re-appearing!

<?php
if(isset($_POST['submit'])) {
  echo'
  <script>
  alert(\'Reply successfully flagged!\');
  window.location.reload();  
  </script>
  ';
}
?>

<form method="post">
<input type="submit" name="submit">
</form>

Note: I need the alert to be in the if statement - I can't just use pure Javascript (such as onclick )!

Answer 1

The problem here is, when you make a reload, it will trigger the POST parameters to be sent, ie, the $_POST['submit'] will be set . It is better to set a SESSION flag instead.

<?php
if(isset($_POST['submit'])) {
  echo'
  <script>
  alert(\'Reply successfully flagged!\');
  location.href = location.href;  
  </script>
  ';
}
?>

Answer 2

change

window.location.reload(); 

with

location.href = window.location.href;
