需要引入的界面
//引入文件 import { formatRichText } from '../../utils/text.js' //獲取數據接口 async getActicle(){ const mydata=await this.$myRequest({ url:"/api.php/grow/chengzhang_info", method: 'POST', data:{ id:25 } }) //formatRichText 調用方法
this.showaticle=formatRichText(mydata.data.data.this_info.content); },
//頁面中顯示
<rich-text :nodes="showaticle"></rich-text>
