错误|Help当我试图修改nav-link上的类时，jquery没有正确启动。可能是被其他js阻塞了？

我正在创建我的index.php文件，其中包括once header.php，sidebard.php，和footer.php 一些页面被从工具条菜单中选择的条件调用。我试图改变活动的导航链接，当另一个项目被点击，并添加“活动”到类。
以下是我的sidebar.php的内容

<!-- Sidebar -->
<div class="sidebar">
  <!-- Sidebar Menu -->
  <nav class="mt-2">
    <ul class="nav nav-pills nav-sidebar flex-column" data-widget="treeview" role="menu" data-accordion="false">

      </li>
    </ul>
  </nav>
  <!-- /.sidebar-menu -->
</div>
<!-- /.sidebar -->

'
这是我的footer.php，其中包含了触发该操作的jquery。

<!-- script to change the selected active nav-link -->

<script>$(document).ready(function () { 
$('.nav-link').click(function(e) {
$('.nav-link').removeClass('active');        
$(this).addClass("active");

});
});
</script>

环境

AdminLTE版本：[例如，版本3.0.4]
操作系统：[例如微软 windows 10]
浏览器（版本）：[例如Chrome（最新）]

我错过了什么吗？请帮帮我。

用于管理员LTE 3

如果要输入URL，例如：网址/编辑/3

这个代码对我有效 *

/*** add active class and stay opened when selected ***/
var url = window.location;

// for sidebar menu entirely but not cover treeview
$('ul.nav-sidebar a').filter(function() {
    if (this.href) {
        return this.href == url || url.href.indexOf(this.href) == 0;
    }
}).addClass('active');

// for the treeview
$('ul.nav-treeview a').filter(function() {
    if (this.href) {
        return this.href == url || url.href.indexOf(this.href) == 0;
    }
}).parentsUntil(".nav-sidebar > .nav-treeview").addClass('menu-open').prev('a').addClass('active');
