jQuery没有使用php include运行 - jQuery didn't run by using php include

当我包含文件header.php时，我面临着 jQuery 的问题，index.php无法运行。导航侧边栏包括在内，但是当我按下 V 形时，什么也没发生？它仅在我直接包含header_user.php而不检查header.php中的UserType时才有效。我不能直接包含header_user.php，因为我需要根据UserType显示页面。在此代码中，假设当前UserType是USER。请帮忙。我不知道问题出在哪里。

索引.php

发现在我按如下方式更改查询后，jQuery 起作用了。有人可以解释为什么会这样吗？

标头.php

<?php
    $UType = $_SESSION['UserType'];
        if($UType == "USER")
        {
            include 'header_user.php';
        }
        else if ($UType == "SUPERIOR")
        {
            include 'header_superior.php';
        }
        else if ($UType == "ADMIN")
        {
            include 'header_admin.php';
        }
        else 
        die("Not a Valid User Type.");
?>

我刚刚收集了所有源代码并在本地测试了您的 HTML。我遇到了一些错误，所以我建议将您的代码更改为：

index.php （将 JS 代码移到 jQuery 和 Bootstrap 脚本标签下）

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<?php
    require_once 'session.php';
    require_once 'connection.php';
?>
<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>Nav Sidebar</title>
        <link href="bootstrap/css/bootstrap.min.css" rel="stylesheet">
        <link href="bootstrap/css/dashboard.css" rel="stylesheet">
    </head>
    <body>
        <?php include 'header/header.php'; ?>
        <script src="jquery-1.11.1.min.js"></script> 
        <script src="bootstrap.min.js"></script>
        <script>
            var change = true;
            $(document).ready(function () {
                $('[data-toggle=offcanvas]').click(function () {
                    $('.row-offcanvas').toggleClass('active');
                });
            });
            function toggle_caret() {
                $("#caret1").toggleClass("glyphicon-chevron-down", change);
                $("#caret1").toggleClass("glyphicon-chevron-left", !change);
                change = !change
            }
        </script>
    </body>
</html>

header.php （删除了数据库代码，因为这似乎是问题的根源）

<?php
$UType = $_SESSION['UserType'];
if($UType == "USER")
{
    include 'header_user.php';
}
else if ($UType == "SUPERIOR")
{
    include 'header_superior.php';
}
else if ($UType == "ADMIN")
{
    include 'header_admin.php';
}
else
{ 
    die("Not a Valid User Type.");
}
?>

header_user.php（添加缺少的结束div标记）

<div class="container-fluid">
    <div class="row">
        <div class="col-sm-3 col-md-2 sidebar">
            <ul class="nav nav-sidebar">

                <li onclick="toggle_caret()"><a href="#" data-toggle="collapse" data-target="#sub1"><span class="glyphicon glyphicon-list-alt"></span>&nbsp;&nbsp;Requisition<small><span style="float:right" id="caret1" class="glyphicon glyphicon-chevron-down"></span></small></a>
                </li>
                <ul class="nav collapse" id="sub1">
                    <li><a href="#"><span class="glyphicon glyphicon-file"></span>&nbsp;&nbsp;Form</a>

                    <li><a href="#">Status</a>

                    <li><a href="#"><span class="glyphicon glyphicon-ok"></span>&nbsp;&nbsp;Approved</a>
                    </li>
                    <li><a href="#"><span class="glyphicon glyphicon-remove"></span>&nbsp;&nbsp;Rejected</a>

                    <li><a href="#"><span class="glyphicon glyphicon-refresh"></span>&nbsp;&nbsp;In Process</a>
                    </li>
