1. 在app.json中添加如下配置
renderer: skyline, // 声明渲染模式
lazyCodeLoading: requiredComponents, // 声明依赖注入
rendererOptions: { skyline: {defaultDisplayBlock: true, // 默认为块布局defaultContentBox: true, // 默认开启盒模型disableABTest: true // 禁用AB测试}
},
componentFramework: glass-easel // 使用的组件框架2. 由于在Skyline模式下不支持页面全局滚动也不支持原生导航栏所以在页面的json配置文件中还要添加如下配置
{usingComponents: {},disableScroll: true,navigationStyle: custom
} 2. 主要组件介绍
1. sticky-section 吸顶布局容器
仅支持作为 scroll-view typecustom 模式的直接子节点。
2. sticky-header 吸顶布局容器
仅支持作为 scroll-view typecustom 模式的直接子节点或 sticky-section 组件直接子节点。
3. grid-view 网格布局容器可实现网格布局、瀑布流布局等
仅支持作为 scroll-view typecustom 模式的直接子节点。按需渲染节点比 Webview 兼容实现具备更好的性能。 3. 所有代码实现

}
3. 以下是JavaScript文件代码
// index.jsimport { getLandscapeImages} from ./datafunction getNewList() {const newList new Array(20).fill(0);const imgUrlList getLandscapeImages();let count 0;for (let i 0; i newList.length; i) {newList[i] {id: i1,title: scroll-view,desc: 默认只会渲染在屏节点会根据直接子节点是否在屏来按需渲染,time: 19:20,like: 88,image_url: imgUrlList[(count) % imgUrlList.length],}};return newList;
}Page({data: {// 顶部列表数据topList: new Array(15).fill(0),// 底部列表数据bottomList: getNewList(),// 网络布局参数crossAxisCount: 2,crossAxisGap: 8,mainAxisGap: 8,// 顶部布局参数menuTop: 0,menuHeight:0,menuLeft:0},onLoad() {const res wx.getMenuButtonBoundingClientRect();this.setData({menuTop: res.top,menuHeight: res.height,menuLeft: res.width 10})},bindSrollToLower() {this.setData({bottomList: this.data.bottomList.concat(getNewList())})},})
4. 以下是上面JavaScript代码中引入的本地模拟数据文件data.js代码
