热消息:Vue3 +element-plus+ wangEditor 富文本编辑器+前端七牛云上传

来源:博客园


【资料图】

我用的vue3,element-plus ,没用ts 搭建wangEditor参考 地址https://www.cnblogs.com/xbxxf/p/16791084.html 七牛云安装参考地址https://blog.csdn.net/ldoit/article/details/121533204本来就是抄大佬的,就不复制粘贴了 主要是整理关于七牛云部分的代码,秉着复制就能用的原则,我把自己封装好的组件复制过来,改改参数即可使用 新建tokenTools.js文件

wangEditor 封装组件wangEditor_qiniu.vue 里面注释我感觉还行,更改里面的参数啥的就行了

使用 <script setup> import wangEditor from "@/components/wangEditor_qiniu.vue" const assemblyWditor = ref(null) assemblyWditor.value.updateHtmlPlay() // 若要清空 则调用子组件方法 鼠标必须要在富文本里面才能生效 </script >
