                id: 0,
                param:[]
            };
        },
        
        //开始的加载数据（用于加载项目分类）
        onLoad() {
            this.loadData()
        },
        
        methods: {
            loadData: function() {
                this.param = {
                    url: 'sort/getSortlist'
                };
                this.$xuehu.request(this.param).then(res=>{
                    this.diaryList = res.data.data;
                })
            },
