harmony 鸿蒙开发详情页
开发详情页
详情页以图表的形式展示一周内空气质量指标值。本页面由两部分组成：标题栏和图表栏；在图表栏，考虑显示效果，我们使用多个div替代chart组件来实现图表功能。
首先，添加一个根节点div，并设置flex-direction属性为column，使两栏纵向排列，代码结构如下：
<div class="container">
<div class="header" onclick="backMain">
<image class="back" src="common/ic_back.png"></image>
<text class="title">
历史记录
</text>
</div>
<list class="chart-list">
</list>
</div>
其中onclick=“backMain”为返回主页事件，detail.js中的代码实现如下：
import router from '@system.router'
export default {
backMain() {
router.replace({
//页面地址
uri: 'pages/index/index',
params: {
//返回主页时带的参数
selectedCityIndex: this.selectedCityIndex
}
});
}
}
其次，在list中添加div组件来实现图表效果。
详情页完整代码如下：
detail.hml
<div class="container">
<div class="header" onclick="backMain">
<image class="back" src="common/ic_back.png"></image>
<text class="title">
历史记录
