我在我的 WordPress 网站上遇到了这个错误“Uncaught TypeError: $ is not a function at (index):2”我找到了这个解决方案来添加var $ = jQuery.noConflict();之前$( document ).ready(function(){但是，我在网站的主题文件夹中找不到“$( document ).ready(function(){”代码来修复它。这是通过 Chrome 浏览器的检查、源窗口获得的确切代码<html class="no-js" itemscope itemtype="https://schema.org/WebPage"><head><meta charset="UTF-8" /><meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1" /><link rel="alternate" hreflang="en" href="https://ccsi.global/"/><link rel="shortcut icon" href="https://ccsi.global/wp-content/uploads/2018/05/imageedit_89_3942571748.png" type="image/x-icon" /><link type="text/css" media="all" href="https://ccsi.global/wp-content/cache/autoptimize/css/autoptimize_9668264b3a77ccf7dc30b539d4038dbc.css" rel="stylesheet" /><title>Comcapint – Home – Compliance and Capacity Skills International</title><link rel='dns-prefetch' href='//fonts.googleapis.com' /><link rel='dns-prefetch' href='//s.w.org' /><link rel="alternate" type="application/rss+xml" title="Comcapint » Feed" href="https://ccsi.global/feed/" /><link rel="alternate" type="application/rss+xml" title="Comcapint » Comments Feed" href="https://ccsi.global/comments/feed/" /> <script type="text/javascript">window._wpemojiSettings = {"baseUrl":"https:\/\/s.w.org\/images\/core\/emoji\/13.0.0\/72x72\/","ext":".png","svgUrl":"https:\/\/s.w.org\/images\/core\/emoji\/13.0.0\/svg\/","svgExt":".svg","source":{"concatemoji":"https:\/\/ccsi.global\/wp-includes\/js\/wp-emoji-release.min.js?ver=5.5"}};$(".nav-tabs a").click(function(){ $(this).tab('show');});$('.nav-tabs a').on('shown.bs.tab', function(event){ var x = $(event.target).text(); // active tab var y = $(event.relatedTarget).text(); // previous tab $(".act span").text(x); $(".prev span").text(y);});});

大多数 WordPress 模板已经调用 noConflict()
当您想$在代码中使用时，最好使用 IIFE 包装器
(function($){
// can use $ here
$(document).ready....
})(jQuery);
jQuery还要确保您在加载库之前没有尝试使用。使用wp_enqueue_script()将解决这个问题
