export default getWeek (){
    let newNum = new Date(newStr).getDay();
    let week =
      newNum === 0
        ? "周日"
        : newNum === 1
        ? "周一"
        : newNum === 2
        ? "周二"
        : newNum === 3
        ? "周三"
        : newNum === 4
        ? "周四"
        : newNum === 5
        ? "周五"
        : newNum === 6
        ? "周六"
        : "";
        return week
}

把文件放入src/utils/utils.js 中

引入并使用

import { getWeek } from "@/src/utils/utils.js";
export default {
  methods: {
    do() {
      getWeek();
    },
  },
};
