directives: {
      preventReClick: {
        inserted(el, binding) {
          el.addEventListener('click', () => {
            if (!el.disabled) {
              el.disabled = true
              setTimeout(() => {
                el.disabled = false
              }, binding.value || 3000)
            }
          })
        }
      },
    },
