Question

我在单独的javascript文件中有一个用于表单提交的确认对话框。该文件的链接包含在php文档中。但确认框没有响应。代码如下。

javascript代码。

function getConfirm() {
  var retVal = confirm("Do you want to continue ?");
  if (retVal == true) {
    document.write("User wants to continue!");
    return true;
  } else {
    Document.write("User does not want to continue!");
    return false;
  }
}

下面是php代码

<?php require "config.php"; $requests=a rray(); $sql="SELECT activity_type FROM activity" ; foreach ($dbo->query($sql) as $row) { $requests[] = $row['activity_type']; } ?>

在表单标签上使用onsubmit而不是onclick on submit按钮来触发提交事件。

<!DOCTYPE html>

<html>

<head>
  <meta charset="UTF-8">
  <link rel="stylesheet" type="text/css" href="layout.css">
  <script language="javascript" type="text/javascript">
  function getConfirm() {
  var retVal = confirm("Do you want to continue ?");
  if (retVal == true) {
    document.write("User wants to continue!");
    return true;
  } else {
    Document.write("User does not want to continue!");
    return false;
  }
}
  </script>

  <title>Title of the document</title>
</head>
<div>

  <body>
    <?php include( '/templates/header.php'); ?>


    <section id="sidebar">
