插件:从模态访问toolbarEvent

My plugin inserts a button in the composer toolbar. This toolbar opens a modal, and when the modal is closed I want to add text to the post. Everything works perfectly except the last step, because I’m struggling to give the modal access to the composer.

If I put the button under a menu in the toolbar, everything works fine:

      api.modifyClass("controller:composer", {
        pluginId: "discourse-n8n-wf",
        actions: {
          showWfModal2() {
            showModal("discourse-n8n-wf").setProperties({"toolbarEvent": this.toolbarEvent});
          },
        },
      });
      api.addToolbarPopupMenuOptionsCallback(() => {
        return {
          action: "showWfModal2",
          icon: "network-wired",
          label: "n8n workflow"
        };
      });

But if I put it on the top level, I don’t seem to have access to the toolbarEvent to pass to the modal

      Composer.reopen({
        actions: {
          showWfModal: function () {
            console.log(this.toolbarEvent); // undefined
            showModal('discourse-n8n-wf', {title:'Insert n8n workflow'});
          }
        }
      });

      api.onToolbarCreate(toolbar => {
        toolbar.addButton({
          id: 'discourse-n8n-wf',
          group: 'extras',
          icon: 'network-wired',
          action: 'showWfModal',
          title: 'Insert workflow'
        });
      });

Any tips?

The toolbarEvent should be available in your modal controller (discourse-n8n-wf), you don’t need to pass it. You can also look at how other modals do this, for example, see discourse-post-event-builder.js.es6 in the poll plugin.

Thanks, Penar! I’m not quite there yet though:

I found the file you referenced in the discourse-calendar plugin (couldn’t find it in the poll one), but there it seems like the toolbarEvent is indeed being passed in the action (through setProperties())?

Was just wondering whether you had any more thoughts here, @pmusaraj?

不确定你是否还在纠结这个问题,但我深入研究了如何从模态框访问工具栏事件,并发现你可以像这样将事件作为参数传递:

action: (event) =>

所以我这样使用了它:

  const composerController = api.container.lookup('controller:composer');

  api.onToolbarCreate((toolbar) => {
    toolbar.addButton({
      id: 'math-editor',
      group: 'extras',
      icon: 'square-root-alt',
      sendAction: (event) => composerController.send('showMathEditor', event),
      title: themePrefix('insert_equation'),
    });
  });

然后你可以在你的 action: {} 方法 中像这样使用它:

@action
showMathEditor(event) {
   showModal('matheditor-modal').set('toolbarEvent', event);
}

多年后,我也遇到了同样的问题(在模态框中无法访问 toolbarEvent),这个解决方案也帮到我了。

      api.onToolbarCreate((toolbar) => {
        toolbar.addButton({
          ...
          sendAction: (event) =>
            toolbar.context.send("triggerMyModal", event),
          ...
        });
      });

      api.modifyClass("component:d-editor", {
        modal: service(),
        pluginId: "poll",
        actions: {
          triggerMyModal(toolbarEvent) {
            this.modal.show(MyCustomModal, {
              model: {
                toolbarEvent,
              },
            });
          },
        },
      });

感谢 Keegan 的帮助。
