vue 禁止按钮重复点击请求接口自定义指令

1.新建repeatStop.js文件

import Vue from 'vue'
// 阻止按钮重复提交
Vue.directive("repeatStop", {
  bind: function (el, binding) {
    function clickHandler (e) {
      if (el.contains(e.target)) {
        if (!el.disabled) {
          el.disabled = true
          setTimeout(() => {
            el.disabled = false
          }, binding.value || 3000)
        }
        return false;
      }
    }
    el.bffClick = clickHandler;
    document.addEventListener('click', clickHandler);
  },
  unbind (el) {
    document.removeEventListener('click', el.bffClick);
    delete el.bffClick;
  },
})

2.main.js中引入

import './util/repeatStop.js'

3.页面模板中使用，v-stopBtnRepeat="毫秒"

<el-button @click="onSubmit" v-repeatStop="5000">提交</el-button>
