如果让我猜的话,我会说这个文件在一个子文件夹中

确保使用相对于域根而不是当前文件的路径包含脚本:

<script src="/js/jquery.min.js"></script>
<script src="/js/scripts.js"></script>


这将确保您的脚本可以被找到,无论您在站点的何处。

您需要将代码包装到

$(function() {
  // your code here...
});
这将确保您的代码在您访问的所有DOM元素都已可用的情况下按预期工作。至于jQuery本身,尝试用include替换本地jQuery

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>


看看这是否有帮助。如果是这样,则本地文件未正确包含—可能是错误的文件夹/子文件夹。

每当您看到未定义
$时,
表示未加载jquery。添加以下内容:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.min.js"></script>


还要记住,此路径必须位于所有其他jquery文件或脚本之上。

请检查jquery文件路径 在“就绪事件”中编写脚本


var$=jQuery
添加到脚本顶部,如

<script type='text/javascript'>
   var $ = jQuery;
   // your functions here...
</script>
推荐:

在关闭
标记之前添加脚本,如

<!DOCTYPE HTML>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
    <title>Your Website</title>
</head>
<body>
    <header>
    </header>

    <section>
    </section>

    <aside>
    </aside>

    <footer>
    </footer>


    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
    <script>window.jQuery || document.write('your_local_here/jquery.js"><\/script>')</script>
    <script src="custom.js"></script>
    <script>
        // or here
    </script>
</body>
</html>

你的网站
window.jQuery | | document.write('your_local_here/jQuery.js“>”)
//还是在这里

如果jQuery加载正确,原因可能在$-definition中。请尝试用以下方式覆盖它:

jQuery(document).ready(function($){
   //Now you can use $
});

看到了吗,我的朋友:jQuery没有被加载,请检查您的路径。
