vue3中update:modelValue的使用与不生效问题解决

<ChildComponent v-model:title="title" />
//或者
<ChildComponent :modelValue = "title" @update:modelValue = "title = $event">
// 或者
<ChildComponent :title="title" @update:title = "title = $event" />

<wm-tinymce
  ref="editor"
  v-model="data.introduction"
  :min-height="400"
  name="职能管理"
  placeholder="请编辑职能大类"
/>

<div class="tinymce-container">
    <editor
      v-model="tinymceData"
      :api-key="key"
      :init="tinymceOptions"
      :name="name"
      :readonly="tinymceReadOnly"
    />
</div>
