			return {
    
    
				 navbar: ['古代诗词', '网络小说', '网上段子','日常生活'],//导航栏类目
				 currentTab: 0,//当前选中的导航类目
				 swiperHeight:0//动态给定swiper的高度
			}
		},
		onLoad(option) {
    
    
			this.swiperHeight = uni.getSystemInfoSync().windowHeight-25;
			console.log(this.swiperHeight);
		},
		methods: {
    
    
		  tabClick(index){
    
    
			  this.currentTab=index
		  },
		  swiperTab(e) {
    
    
			this.currentTab = e.detail.current; //获取索引
			console.log("this.currentTab",this.currentTab)
		  }
