【vue3】wangEditor 5在vue3中的使用

article 2024/11/21 1:31:27

实现效果：

将wangEditor富文本编辑器进行封装，父组件可以使用子组件富文本编辑器中的数据用于api对接。

1.安装

官网：https://www.wangeditor.com

# Vue2 安装
yarn add @wangeditor/editor-for-vue
# 或者 npm install @wangeditor/editor-for-vue --save
 
# Vue3 安装
yarn add @wangeditor/editor-for-vue@next
# 或者 npm install @wangeditor/editor-for-vue@next --save

2.创建编辑器vue文件

commonEdit.vue

<template>
  <div style="border: 1px solid #ccc">
    <Toolbar
      :editor="editorRef"
      :defaultConfig="toolbarConfig"
      :mode="mode"
      style="border-bottom: 1px solid #ccc"
    />
    <Editor
      v-model="valueHtml"
      :defaultConfig="editorConfig"
      :mode="mode"
      @onCreated="handleCreated"
      @onChange="handleChange"
      style="height: 500px; overflow-y: hidden;"
    />
  </div>
</template>
 
<script setup lang="ts">
 
  import { watch,onBeforeUnmount,nextTick, ref, shallowRef, onMounted,onBeforeMount } from 'vue'
  //@ts-ignore
  import { Editor, Toolbar } from '@wangeditor/editor-for-vue'
  import '@wangeditor/editor/dist/css/style.css' // 引入 css
 
  // Props：使用属性，子组件接收父组件传递的内容
  const props = defineProps({
    content: { type: String, default: '' }
  })
 
  // Emits：使用事件，将子组件内容传递给父组件。父组件使用 update(content: string) 
  const emit = defineEmits<{ (e: 'update', content: string): void }>()
 
  const mode = ref('default')
 
  // 编辑器实例，必须用 shallowRef
  const editorRef = shallowRef()
 
  // 内容 HTML
  const valueHtml = ref('')
 
  const toolbarConfig = {}
 
  const editorConfig = { 
    placeholder: '请输入内容...' ,
    MENU_CONF:{} as any
  }
 
  // 上传图片配置
  editorConfig.MENU_CONF['uploadImage'] = {
    // form-data fieldName ，默认值 'wangeditor-uploaded-image'。传给后端接口的参数名，重要!
    fieldName: 'file',
    server: 'http://localhost:8080/files/wangEditorUpload'
  }
 
  const handleCreated = (editor:any) => {
    editorRef.value = editor // 记录 editor 实例，重要！
  }
 
  const handleChange = () => { 
    valueHtml.value  = editorRef.value.getHtml()
    emit('update', valueHtml.value) 
  }
 
  // 监听 props 变化，监听父组件传来的content
  watch(() => props.content, (newVal:string) => {
      nextTick(() => {
        if (editorRef.value) {
          // console.log(" 当前编辑器的状态：", editorRef.value); 
 
          // 富文本编辑器按 html 格式回显
          editorRef.value.setHtml(newVal)
          valueHtml.value = newVal
        }
      })
    }
  )
 
  onMounted(async() => {
    await nextTick(); // 延迟渲染，确保 DOM 更新完成
    if(props.content) {
      valueHtml.value = props.content 
    }
  })
 
  // 组件销毁时，也及时销毁编辑器
  onBeforeUnmount(() => {
      const editor = editorRef.value
      if (editor == null) return
      editor.destroy()
  })
 
</script>

3.父组件中引用

<template>
  <el-form :model="form" label-width="auto" style="max-width: 800px">
    <el-form-item label="文章标题">
      <el-input v-model="form.title" />
    </el-form-item>
	<el-form-item label="文章内容">
	  <commonEdit :content="form.html" @update="update"/>
	</el-form-item>
   
    <el-form-item label="文章简介">
      <el-input v-model="form.desc" type="textarea" />
    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="onSubmit(form)">提交</el-button>
      <el-button>取消</el-button>
    </el-form-item>
  </el-form>
</template>

<script lang="ts" setup>
import commonEdit from '../components/commonEdit.vue';
import { reactive } from 'vue'
import { addArticle } from '../api';
import router from '../router';
// do not use same name with ref
const form = reactive({
  title: '',
  desc: '',
  html:'',
})

const onSubmit = (data:any) => {
	console.log(data);
  addArticle(data)
  router.push('/article')
}

// 更新富文本编辑器内容
  const update = (content:string) => {

    form.html=content
  };

</script>
