element select 实现从服务器搜索 模糊查询

效果如下：

代码：

data中定义：

 optionsMatching: [],
      scanBlurry: [],
      loading: false,

  remoteMethod(query) {
      let _this = this;
      if (query !== "") {
        _this.loading = true;
        searchMatching(query).then((res) => {
          _this.loading = false;
          _this.optionsMatching = res.map((item, index) => {
            return {
              value: item,
              label: item,
              index: index,
            };
          });
          console.log(_this.optionsMatching, "_this.optionsMatching");
        });
      } else {
        this.optionsMatching = [];
      }
    },
