1、按照上方 知识点总结 模块,总结今天所学知识点;
2、有以下广告数据(实际数据命名可以略做调整)
ad_data = {
tv: [
{img: 'img/tv/001.png', title: 'tv1'},
{img: 'img/tv/002.png', title: 'tv2'},
{img: 'img/tv/003.png', title: 'tv3'},
{img: 'img/tv/004.png', title: 'tv4'},
],
phone: [
{img: 'img/phone/001.png', title: 'phone1'},
{img: 'img/phone/002.png', title: 'phone2'},
{img: 'img/phone/003.png', title: 'phone3'},
{img: 'img/phone/004.png', title: 'phone4'},
]
}
i) 有两个大标题,电视和手机,点击对应的标题,渲染对应的数据
ii) 一个字典作为一个显示单位,定义一个子组件进行渲染(涉及父子组件传参)
3、在第2题基础上,页面最下方有一个 h2 标签,用来渲染用户当前选择的广告(点击哪个广告就是选中哪个广告)
i)当没有点击任何广告,h2 标签显示:未选中任何广告
ii)当点击其中一个广告,如tv1,h2 标签显示:tv1被选中
