Vue3.0 Vite + windicss + ...实战项目

二十六.如何实现一个全局的自定义指令, 实现权限管理

当后端返回一个数组里面有权限管理对应的数据,我想实现用自定义指令去实现某个按钮或者图表显示隐藏,该怎么做了?

1. 创建一个directives/directivePermission.js 文件
import store from "~/store";
const hasPermission = (value, el = false) => {
  if (!Array.isArray(value)) { // 从指令上传递过来的必须要要是一个数组,不然抛出异常
    throw new Error(`需要配置权限,例如 v-permission="['getStatistics3,GET']"`);
  }
  const hasAuth = value.findIndex((i) => store.state.ruleNames.includes(i)) != -1;
  console.log(hasAuth); // true
  if (el && !hasAuth) {
    el.parentNode && el.parentNode.removeChild(el); // 用父节点移除当前父节点的子节点
  }

  return hasAuth
};

export default {
  install(app) {
    app.directive("permission", {
      mounted(el, binding) {
        // console.log(el); // 拿到的是当前调用指令的标签元素
        // console.log(binding); // 具体数据 binding.value 是你在页面传递过来的参数
        hasPermission(binding.value, el);
      },
    });
  },
};

2. 需要使用的父页面 index.vue
 <!-- 图表渲染 用自定义指令实现后端权限匹配 显示隐藏 -->
  <CheckEChart v-permission="['getStatistics3,GET']" />

二十八.修改浏览器滚动条的样式

/* 修改浏览器滚动条的样式 */
::-webkit-scrollbar {
  width: 4px;
  height: 6px;
}
::-webkit-scrollbar-corner {
  display: block;
}
::-webkit-scrollbar-thumb {
  border-radius: 8px;
  background-color: rgba(0, 0, 0, 0.2);
}
::-webkit-scrollbar-thumb,
::-webkit-scrollbar-track {
  border-right-color: transparent;
  border-left-color: transparent;
  background-color: rgba(0, 0, 0, 0.1);
}

二十九.引入富文本

一 .安装两个包:
 1. 1.  npm i tinymce 
 1. 2. npm i @tinymce/tinymce-vue
二. 从node_modules/tinymce 拷贝样式文件到public 目录下
中文包zh-Hans.js下载地址: https://www.tiny.cloud/get-tiny/language-packges/

    <editor v-model="content" tag-name="div" :init="init" />
</template>
<script setup>
