Question

我的程序的场景是当我提交表单时，表单操作转到xyz.php。在xyz.php中，我只是使用了 INCLUDE("abc.html")重定向到另一个HTML页面，现在abc.html包含一些HTML标签以及“ JAVASCRIPT” ，但是当我的表单提交后，页面重定向到了{{ 1}}。 abc.html包含HTML和Javascript代码。 HTML内容可见，但javascript无法正常工作，

我是PHP新手。谢谢

下面是“ student.php”文件

abc.html

这里是“ teachdata.html”

    </div>
</body>
</html>

Answer 1

好的，这是最简单的解决方案，但不好保留。

在主脚本中包含js：

<html>
<head>
   <title>Marks Entering</title>
   <link rel="stylesheet" type="text/css" href="teachdata.css">
   <script src="teachtab.js"></script>
</head>  
<!-- keep the rest -->

在teacherdata.html中，摆脱<html>，<body>，<head>的所有内容，

<h1> Welcome teacher section.....</h1>

<!-- to -->

</div>

但是，重定向到teachdata.html（或使其成为php脚本teachdata.php并在其中包含一条消息）会更好。

    if($run1 == true) {
        header("Location: teachdata.php?msg=success");
    } else {
    //....

在teacherdata.php中，您现在可以将消息内嵌显示为普通的html

   <?php
   if (isset($_GET['msg'])) {
       echo "<div>Message: " . $_GET['msg'] . "</div>";
   }
   ?>

，或者如果您确实希望这样做，则发出普通的旧JavaScript警报：

   <?php
   if (isset($_GET['msg'])) {
       echo "<script> alert('" . $_GET['msg'] . "'); </script>";
   }
   ?>

请查看准备好的角色。您的代码不安全，开放到sql注入（Google“ Bobby Tables”和“ Sql Injection”）。
您确定您的应用需要3个不同的数据库吗？

包含的HTML文件javascript无法正常工作
