当我包含文件index.php时，我遇到header.php中的jQuery没有运行的问题。包括导航侧边栏，但当我按下雪佛龙时，什么都没发生？仅当我直接包含header_user.php而未检查UserType中的header.php时，它才有效。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为USER。请帮忙。我不知道是什么问题。
的index.php

修改
我发现在我更改了下面的查询后，jQuery工作了。有人可以解释为什么会这样吗？
的header.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.");
?>
答案 0 :(得分：0)
我刚收集了所有来源并在本地测试了您的HTML。我收到了一些错误，因此我建议您将代码更改为：
index.php （在jQuery和Bootstrap脚本标记下移动了JS代码）
<!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，因为这似乎是您问题的根源）
<?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代码）
<div class="container-fluid">
<div class="row">
<div class="col-sm-3 col-md-2 sidebar">
<ul class="nav nav-sidebar">
<li class="active"><a href="#"><span class="glyphicon glyphicon-dashboard"></span> Dashboard<span class="sr-only">(current)</span></a>
</li>
<li onclick="toggle_caret()"><a href="#" data-toggle="collapse" data-target="#sub1"><span class="glyphicon glyphicon-list-alt"></span> Requisition<small><span style="float:right" id="caret1" class="glyphicon glyphicon-chevron-down"></span></small></a>

<ul class="nav collapse" id="sub1">
