getData() {
      this.$ajax.get('/api/commodityCategory/list')
        .then(response => {
          let list = response.data;
          this.tag1 = list;
          for(let i = 0;i < this.tag1.length;i++){
            this.tag1[i].visible1 = 'false';
          }
          console.log(this.tag1);
          console.log(response.data.data);
        })
        .catch(function(response) {
          console.log(response);
        });
          
    }

在create中执行getData方法后数据中的visible1并没有改变,怎么解决
