1.鸿蒙视图效果

 点击menu菜单一项，跳转页面，底部菜单栏和轮播布局和轮播图

2.js业务数据和事件

import prompt from '@system.prompt';
import router from '@system.router';
export default {
    data: {
        title: 'World',
        fundatas:[{"fathermenu":"员工管理","childmenu":[{"icon":"/common/emp.png","text":"查询员工"},{"icon":"/common/emp.png","text":"添加员工"},{"icon":"/common/emp.png","text":"删除员工"},{"icon":"/common/emp.png","text":"更新员工"}]},

        ]
    },
    clickitem(itemvalue)
    {

        if(itemvalue=="查询员工")
        {
            this.$element("menu").show({
                x: 360,
                y: 120
            });
            //this.$element("menu").show();

        }
        prompt.showToast({
            message:"点击了菜单"+itemvalue

        })
    },
    menuSelected(e) {
        prompt.showToast({
            message:"你选择查询的值是:"+e.value
        })

        router.push({
            uri:"pages/index/index"

        })


    }
}

3.页面视图代码

<div class="container">
    
    <list  class="listview">
       <block  for="{{fundatas}}">
           <list-item-group  class="groupview">
               <list-item class="listitem">
                   <text  class="tv1">{{$item.fathermenu}}</text>
               </list-item>
               <block  for="{{ (index,value)  in $item.childmenu}}">
                 <list-item class="listitemone" onclick="clickitem({{value.text}})">
                    <image  class="cimg"  src="{{value.icon}}"></image>
                    <text class="tv2">{{value.text}}</text>
