WordPress中TinyMCE插件初始化失败：r is not a constructor错误求助

问题描述 #

我有一个WordPress网站，设有用户创建文章的页面。已配置TinyMCE将表单内特定字段转换为TinyMCE编辑器字段，基础功能正常，但多数自带插件无法工作，反复出现错误：Failed to initialize plugin: wordcount TypeError: r is not a constructor。在全新WordPress安装环境中测试该问题仍存在。

当前使用的TinyMCE初始化代码 #

jQuery(document).ready(function($){
    
        tinymce.init({
          selector: '.tinymce>div>div>textarea',
          suffix: ".min",
          height: 200,
          plugins: "codesample autosave code image link lists media preview searchreplace textcolor wordcount hr",
          autosave_restore_when_empty: true,
          autosave_retention: '60m',
          codesample_languages: [
            {text: 'HTML/XML', value: 'markup'},
            {text: 'JavaScript', value: 'javascript'},
            {text: 'CSS', value: 'css'},
            {text: 'PHP', value: 'php'},
            {text: 'Ruby', value: 'ruby'},
            {text: 'Python', value: 'python'},
            {text: 'Java', value: 'java'},
            {text: 'C', value: 'c'},
            {text: 'C#', value: 'csharp'},
            {text: 'C++', value: 'cpp'},
            {text: 'Markup', value: 'markup'},
            {text: 'Arduino', value: 'arduino'},
            {text: 'ARM Assembly', value: 'armasm'},
            {text: 'Batch', value: 'batch'},
            {text: 'Bash', value: 'bash'},
            {text: 'ASP.NET (C#)', value: 'aspnet'},
            {text: 'Brainfuck', value: 'brainfuck'},
            {text: 'JSON', value: 'json'},
            {text: 'Markdown', value: 'markdown'},
            {text: 'TypeScript', value: 'typescript'},
            {text: 'ASP.NET (C#)', value: 'aspnet'},
            {text: 'Rust', value: 'rust'}
          ],
          toolbar: 'preview searchreplace | codesample image link | lists hr | bold italic textcolor | h1 h2 h3 h4 | alignleft aligncenter alignright | bullist numlist outdent indent | undo red | wordcount-',
          // content_style: 'body { font-family:Helvetica,Arial,sans-serif; font-size:14px }'
        });
});

核心困惑 #

特别重要：上述代码必须粘贴到浏览器控制台才能生效，原因是编辑器元素通过JS动态添加，初始化函数执行时元素尚未加载，不知道该如何处理这个时机问题。
