简介vue自定义富文本组件WangEditor

组件文件.vue
```
<template>
  <div style="border: 1px solid #ccc">
    <Toolbar
      style="border-bottom: 1px solid #ccc"
      :editor="editorRef"
      :defaultConfig="toolbarConfig"
      :mode="mode"
    />
    <Editor
      style="min-height: 300px; overflow-y: hidden"
      v-model="valueHtml"
      :defaultConfig="editorConfig"
      :mode="mode"
      @onCreated="handleCreated"
      @onChange="onChange"
    />
  </div>
</template>

import { onBeforeUnmount, ref, shallowRef, onMounted } from "vue";
import { Editor, Toolbar } from "@wangeditor/editor-for-vue";
import { store } from "@/store";
export default {
  name: "WangEditor",
  modelValue: {
    type: String,
    default: "",
  },
  emits: ["update:modelValue"],
  components: { Editor, Toolbar },
  props: {
    editorHtml: "",
    modelValue: {
      type: String,
      default: "",
    },
  },
  methods: {
    onChange(editor) {
      this.$emit("update:modelValue", this.valueHtml);
    },
  },
  setup(res) {
    const token = store.getters["user/token"];
    const user = store.getters["user/userInfo"];

// 编辑器实例，必须用 shallowRef
    const editorRef = shallowRef();
    // 内容 HTML
    let valueHtml = ref("");
    if (res.modelValue !== undefined) {
      valueHtml = ref(res.modelValue);
    }
    // 模拟 ajax 异步获取内容
    // onMounted(() => {
    //   setTimeout(() => {
    //     valueHtml.value = "<p>模拟 Ajax 异步设置内容</p>";
    //   }, 1500);
    // });

// 组件销毁时，也及时销毁编辑器
    onBeforeUnmount(() => {
      const editor = editorRef.value;
      if (editor == null) return;
      editor.destroy();
    });

const handleCreated = (editor) => {
      editorRef.value = editor; // 记录 editor 实例，重要！
    };

return {
      editorRef,
      valueHtml,
      mode: "default", // 或 'simple'
      toolbarConfig,
      editorConfig,
      handleCreated,
    };
  },
};
</script>

使用.vue
```
<el-form-item label="内容：" prop="content">
	<WangEditor v-model="form.content" />
</el-form-item>
```
