 data: {
        level: 1,
        page: 1,
        list: [],
        status:true
    },

myTab: function(e) {
        
        if(!this.data.status){
            return
        }
        var a = this, i = t.pdata(e).level;
        a.setData({
            level: i,
            page: 1,
            list: [],
            status:false
        }), a.getList();
        setTimeout(a.setStatus,1500)
