this.$xx是零碎定义的属性,罕用的: this.$message,this.$route,this.$router,this.$ref(已写过),this.$confirm,this.$emit,this.$store,this.$loading...

### 1.this.$confirm , this.$messageremoveQuestion(id) {      this.$confirm("确定删除吗？", "提醒", {        confirmButtonText: "确定",        cancelButtonText: "勾销",        type: "warning",      }).then(() => {        AdminApi.library          .removeQuestion({            id: id,            pageName: this.pageName,          })          .then((res) => {            if (res.status == "200") {              this.popVisible = false;              this.$message.success("操作胜利！");              this.getQuestionDict();            }          });      });    },
### 2.this.$router,this.$routesetTimeout(() => {              this.$router.push("/enterprise/info/" + this.eid);            }, 3000);$this.$router.push()获取参数：this.$route.params.userId

3.this.$emit组件之间的通信(模态框点击确定提交并敞开模态框)
### 4.this.$store  数据缓存store/index.jsimport Vue from 'vue'import Vuex from 'vuex'Vue.use(Vuex)const store = new Vuex.Store({    state: {        userId: localStorage.getItem('userId'),        userEmail: localStorage.getItem('userEmail'),        userMobile: localStorage.getItem('userMobile'),    },    getters: {        isLogin(state) {            return state.userId && state.userId > 0        },        userId(state) {            return state.userId;        },        userEmail(state) {            return state.userEmail;        },        userMobile(state) {            return state.userMobile;        }    },    mutations: {        login(state, user) {            state.userId = user.id;            state.userEmail = user.email;            state.userMobile = user.mobile;            localStorage.setItem('userId', user.id);            localStorage.setItem('userEmail', user.email);            localStorage.setItem('userMobile', user.mobile);        },        logout(state) {            state.userId = 0;            state.userEmail = '';            state.userMobile = '';            localStorage.removeItem('userId');            localStorage.removeItem('userEmail');            localStorage.removeItem('userMobile');        }    }})export default store应用：this.$store.commit("login", user);     this.$store.getters.isLogin ? "是" : "否";     this.form.operatorName = this.$store.getters.adminName;
