uniapp 小程序周选择器

这里贴出来的是子组件的代码，父组件只是打开了一下popup

//  打开了一下popup
$refs.popup.open('bottom')

如果不想用子组件的话，直接打开popup就可以用

<template><uni-popup ref="popup" type="bottom" background-color="#fff"><view class="my_popup"><view class="my_selectDeta"><view class="my_button" @click="iconClose">取消</view><view class="my_button" type="primary" @click="confirm">确定</view></view><picker-view :value="selectValue" class="picker-view" @change="pickerChange"><picker-view-column><view v-for="(item, index) in years" :key="index" class="year-item">{{ item }}年</view></picker-view-column><picker-view-column><view v-for="(item, index) in weeks" :key="index" class="weeks-item">{{ `第${index + 1}周(` + item + ')' }}</view></picker-view-column></picker-view></view></uni-popup>
