PHP JavaScript表单弹出窗口

Question

I am trying to have my script be able to use a popup to enter one of the textboxes, which works, but when I go to calculate the values it does not calculate them. 我试图让我的脚本能够使用弹出窗口输入其中一个文本框，该文本框有效，但是当我去计算值时，它不会计算它们。 I think it has something to do with the form id, but I do not know specifically what to change. 我认为这与表单ID有关，但是我不知道具体要更改什么。

 <script type="text/javascript">



 function resetPassword() {    
    var email = prompt("Search Value", "");

if (email != null) {
  document.getElementById("email1").value = email; 
  document.getElementById("frm1").submit();
}


}
</script>

<?php
$emitter = 0;
$rings = 0;
$wave = 0;
$gls = 0;
$tiles = 0;
$fov = 0;
if(isset($_POST['calculate'])) 
{
    $rings = $_POST['rings'];
    $wave = $_POST['wave'];
    $emitter = $_POST['emitter'];
    $gls = round(22 * sin($wave / ($emitter / tan ($emitter / 4))), 2);
    $tiles = round(5 * $rings, 2);
    $fov = round((90 / M_PI) * $gls * (sqrt(9) / 4) * $rings, 2);
}
?>
