我正在使用我在网上找到的一些代码，这将为我提供一个精美的文件上传按钮，该按钮还允许用户将文件拖放到放置区域中。它在 jsfiddle 中工作得很好但是当我通过 Cpanel 将代码添加到我的 Wordpress 文件时，它不起作用。我什么也没做，只是复制并粘贴文件。
错误:
未捕获类型错误:未定义不是函数
指向这个:$(window).load(function(){
未捕获类型错误:$container.imagesLoaded 不是函数 指出 5 件事:
$container.imagesLoaded(function(){- m.Callbacks.j @ jquery.js?ver=1.11.3:2
- m.Callbacks.k.fireWith @ jquery.js?ver=1.11.3:2
- m.extend.ready @ jquery.js?ver=1.11.3:2
- J@jquery.js?ver=1.11.3:2

最佳答案
您是否包含 jquery 库？如果您还没有添加，请添加
if (!is_admin()) add_action("wp_enqueue_scripts", "my_jquery_enqueue", 11);
函数 my_jquery_enqueue() {
wp_deregister_script('jquery');
wp_register_script('jquery', "http". ($_SERVER['SERVER_PORT'] == 443 ? "s": "") . ":https://ajax.googleapis.com/ajax/libs/angularjs/1.3. 15/angular.min.js", false, null);
wp_enqueue_script('jquery');
}
在functions.php文件中
如果您已经这样做了，请检查 var container 是否已在任何位置设置。我在您的示例中没有看到该变量的定义
