注册全局组件:

directives.js

function permissionBtns(el, binding) {
  let data = binding.value.data,
    prop = binding.value.prop,
    val = binding.value.val;
  if (data[prop] == val) {
    el.style.display = "block";
  } else {
    el.style.display = "none";
  }
}

export { permissionBtns };

在main.js中注册

//全局自定义指令
import * as directives from "./js/directives/directives";
Object.keys(directives).forEach((key) => {
  Vue.directive(key, directives[key]);
});

在页面中使用

v-permissionBtns: permissionBtns是注册的名称,

{data: row.data, prop: 'state', val: 2}是参数

<div v-permissionBtns="{ data: row.data, prop: 'state', val: 2 }">

</div>
