自己首先是想到先把接口寫到一個方法里, 然后在別的地方調(diào)用, 但是自己又不知道如何入手
methods: {

/* 把接口寫在方法里 */
getData() {
  this.$http.get(this.$api.dataChart).then(rsp => {
    this.data = rsp.data.data; // tab欄所有圖表數(shù)據(jù)
    console.log("555555", window.data);
  });
},

  this.$http
    .get(this.$api.dataChart)
    .then(rsp => {
      console.log(rsp);

      if (rsp.status == 200) {
        window.data = this.data;
        this.resData = rsp.data.data.device_1;
        let key = "土壤溫度_1";
        let xAxisData = this.resData[key].names;

感覺自己的代碼還有很大的優(yōu)化空間
