import { onMounted, onUnmounted } from "vue";

//vue实例挂载后调用
onMounted(() => {
  document.addEventListener("keydown", (event) => {
    if (event.keyCode == 72) {
      location.reload();
    }
  });
});

//vue实例销毁时调用
onUnmounted("keydown", (event) => {
  document.removeEventListener("keydown", () => {});
