javascript - 确认框不显示并自动删除

Question

请帮帮我。我创建了一个删除过程，其中有一个确认框询问用户是否确定。 但确认框没有出现，并自动删除数据，甚至没有重定向我。请帮助我!

我需要显示确认框(“你确定吗”)以及输入是否正确。它将删除数据并重定向到其他页面。

 <?php
 require_once('connect/connect.php');
 ?>
 <script>
 var r = confirm("Are you sure?");
 if (r == true)
 {
 alert(' item successfuly deleted!!');
 </script>
 <?php

 if(isset($_GET['pid'])){
$sql ='Select * FROM product where pid = '.$_GET['pid'];
$qry = mysql_query($sql);
$data = mysql_fetch_array($qry);
$pname = $data['pname'];
$pstock = $data['pstock'];
}
$sq3="INSERT INTO report VALUES('NULL','".$pname."', '" .$pstock. "', 'Item Deleted' )";
$qry3 = mysql_query($sq3);

$sql2 = 'DELETE FROM product where pid = '.$_GET['pid'];
$qry2 = mysql_query($sql2);
?>
<script>
 window.location.assign('products.php');    
 }
 </script>
 <script>
 else
 {
window.location.assign('products.php');
 }
</script>

Answer 1

您错过了 if 条件的右大括号 }

 <script>
 var r = confirm("Are you sure?");
 if (r == true)
 {
 alert(' item successfuly deleted!!');
 }
 </script>
