开始
关注列表里面的,上拉加载功能
首页做过,直接复制首页的上拉加载代码。
复制之前做好的loadMore组件
import loadMore from '@/components/common/load-more.vue';loadMore

使用 组件
<!-- 上拉加载 --><load-more></load-more>
把list放在新定义的关注里面

guanzhu:{loadtext:"上拉加载更多",list:[// 文字{userpic:"../../static/demo/userpic/12.jpg",username:"哈哈",sex:0, //0 男 1 女age:25,isguanzhu:false,title:"我是标题",titlepic:"",video:false,share:false,path:"深圳 龙岗",sharenum:20,commentnum:30,goodnum:20},// 图文{userpic:"../../static/demo/userpic/12.jpg",username:"哈哈",sex:0, //0 男 1 女age:25,isguanzhu:false,title:"我是标题",titlepic:"../../static/demo/datapic/13.jpg",video:false,share:false,path:"深圳 龙岗",sharenum:20,commentnum:30,goodnum:20},// 视频{userpic:"../../static/demo/userpic/12.jpg",username:"哈哈",sex:0, //0 男 1 女age:25,isguanzhu:false,title:"我是标题",titlepic:"../../static/demo/datapic/13.jpg",video:{looknum:"20w",long:"2:47"},share:false,path:"深圳 龙岗",sharenum:20,commentnum:30,goodnum:20},// 分享{userpic:"../../static/demo/userpic/12.jpg",username:"哈哈",sex:0, //0 男 1 女age:25,isguanzhu:false,title:"我是标题",titlepic:"",video:false,share:{title:"我是分享的标题",titlepic:"../../static/demo/datapic/14.jpg"},path:"深圳 龙岗",sharenum:20,commentnum:30,goodnum:20},]}
循环guan.list
<block v-for="(item,index) in guanzhu.list" :ket="index">

<load-more :loadtext="guanzhu.loadtext"></load-more>
监听处理事件
@scrolltolower="loadmore(index)"
复制首页上拉加载的代码
替换关键字
复制图文的数据到这里。
// 上拉加载loadmore() {if (this.guanzhu.loadtext != "上拉加载更多") {return;}// 修改状态this.guanzhu.loadtext = "加载中...";// 获取数据setTimeout(() => {//获取完成let obj = {userpic: "../../static/demo/userpic/12.jpg",username: "哈哈",sex: 0, //0 男 1 女age: 25,isguanzhu: false,title: "我是标题",titlepic: "../../static/demo/datapic/13.jpg",video: false,share: false,path: "深圳 龙岗",sharenum: 20,commentnum: 30,goodnum: 20};this.guanzhu.list.push(obj);this.guanzhu.loadtext = "上拉加载更多";}, 1000);// this.guanzhu.loadtext="没有更多数据了";}

啦到底部,加载了新的
会有回弹的效果。如果不喜欢可以禁用掉。
首页是在这里加的。
加上这句话就可以了。
"bounce": "none", // 关闭反弹效果
最终修改注意事项。
按照视频中编写代码后,无法触发触底的事件,
解决方法如下:
在scroll-view上加上scroll-top的属性。srcollTopValue这个是自定义的属性值。
同时给scroll-view也加上高度是页面加载后计算出来的高度。

scroll事件。滚动条以滚动 就更新滚动条的高度
