/**
 * Implement the custom directive
 * Make sure the `onClick` method only gets triggered once when clicked many times quickly
 * And you also need to support the debounce delay time option. e.g `v-debounce-click:ms`
 *

  mounted:(el,binding)=>{
      let timer;
    el.addEventListener('click',()=>{
