tinymce v5中的onNodeChange吗？

如何解决tinymce v5中的onNodeChange吗？

我在tinymce（https://moodle.org/plugins/tinymce_glatex）中添加了一个外部插件

我这样将其添加到tinymce.init中

plugins: ['glatex'],toolbar: ' glatex',external_plugins: {
  'glatex': '/images/glatex/tinymce/editor_plugin.js'
},

但是控制台出现错误

Failed to initialize plugin: glatex TypeError: Cannot read property 'add' of undefined

这是glatex中editor_plugin.js的代码

(function () {

        tinymce.create('tinymce.plugins.LatexPlugin',{

          
    init: function (ed,url) {
      ed.addCommand('LatexPlugin',function () {
          ed.windowManager.open({
              file: ed.getParam("moodle_plugin_base") + 'glatex/glatex.PHP',width: 640 + parseInt(ed.getLang('latex.delta_width',0)),height: 480 + parseInt(ed.getLang('latex.delta_height',inline: 1
          },{
              plugin_url: url
          });
      });

      // Register button
      ed.ui.registry.addButton('glatex',{
          title: 'LaTeX Plugin',cmd: 'LatexPlugin',image: url + '/img/latex.png'
      });

      // Node change events
      ed.onNodeChange.add(function (ed,cm,n) {
          cm.setActive('glatex',n.nodeName == 'IMG');
      });

    },getInfo: function () {
        return {
            longname: 'Latex plugin',author: 'Diego Caponera',authorurl: 'http://www.diegocaponera.com',infourl: 'http://www.diegocaponera.com',version: "1.0"
        };
    }
    });

// Register plugin
       tinymce.PluginManager.add('glatex',tinymce.plugins.LatexPlugin)
})();

有人知道这个错误吗？我一直在搜索它，但是没有找到解决方法

解决方法

您所引用的插件似乎是在TinyMCE 5发行之前编写的，因此它很可能使用TinyMCE 4的API。

要使该插件与TinyMCE 5配合使用，需要对其进行更新以与TinyMCE 5的API配合使用。

此处提供了有关从TinyMCE 4迁移到5的文档：https://www.tiny.cloud/docs/migration-from-4x
