vue.js 分页加载,向上滑动,依次加载数据。

export default { layout: 'default', data(){ return{ page:1, pageSize:10, orderListArr:[], prodListLoadingOver:false, prodListLastPage: false, } }, mounted(){ window.addEventListener('scroll', this.handleScroll); }, created(){ this.fetchOrderListAction(); }, methods:{ fetchOrderListAction(){ let reqBody = {}; reqBody.page = this.page; reqBody.pageSize = this.pageSize; this.prodListLoadingOver = false; fetchOrderList(JSON.stringify(reqBody)).then((res) => { let resData = res.data; if (resData.respHeader && resData.respHeader.resultCode === 0) { this.prodListLoadingOver = true; this.orderListArr = resData.respBody.subsList; if(this.page == 1){ this.orderListArr = resData.respBody.subsList; }else{ this.orderListArr = this.orderListArr.concat(resData.respBody.subsList); } if(resData.respBody.subsList.length < this.pageSize){ this.prodListLastPage = true; } }else{ Toast({ message: resData.respHeader.message || "网络异常", }); } }); }, handleScroll(){ let scrollTop = window.pageYOffset || document.documentElement.scrollTop || document.body.scrollTop; let h = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight; //屏幕的高度 let prodListHeight = document.querySelector('.myOrderListWrapper').offsetHeight-h-20; //.myOrderListWrapper 商品列表容器 console.log(scrollTop,":::",prodListHeight) if(scrollTop > prodListHeight && this.prodListLoadingOver && !this.prodListLastPage){ this.page = this.page + 1; this.fetchOrderListAction(); } }, }, destroyed(){ window.removeEventListener('scroll', this.handleScroll); } }
在mounted中注册滚动事件,在destroyed中销毁。。。其他鼠标事件也是如此。
