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，这是有效的，但当我去计算值它不计算它们。我认为它与表单id有关，但我不知道具体要改变什么。
<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);
}
?>
