新建表

这里我加了几个测试字段 createTime、remark、money

// 文档教程: https://uniapp.dcloud.net.cn/uniCloud/schema
{"bsonType": "object","required": [],"permission": {"read": true,"create": true,"update": true,"delete": true},"properties": {"_id": {"description": "ID，系统自动生成"},"createTime":{"bosnType":"string"},"remark":{"bosnType":"string"},"money":{"bosnType":"number"}}
}

效果

完整代码

<template><view><input v-model="form.remark" placeholder="备注" type="text"><input v-model="form.money" type="number" placeholder="金额"><button @click="clickAdd">新增</button><view class="list" v-for="item in list" :key="item._id">{{item.remark}}<button style="width:2em;" @click="clickDelete(item._id)">删除</button></view></view>
