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

	<view>

		<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>

<script setup>

		money: 0
	})
	const list = ref([]);
	const db = uniCloud.database()

	// 新增
	function clickAdd() {
		db.collection('list').add({
			createTime: new Date(),
			remark: form.remark,

		}).then((res) => {
			getList()
			// uni.navigateBack()
		}).catch((err) => {
			uni.showModal({
				content: err.message || '请求服务失败',
				showCancel: false
			})
		})
	}

	onShow(() => {
		getList();
	})

	// 列表查询
	async function getList() {
		let {
			result
		} = await db.collection("list").get();
		console.log(result)
		list.value = result.data;
	}

	async function clickDelete(_id) {
		await db.collection("list").doc(_id).remove();
		getList()
	}
</script>

<style scoped>
	.list {
		color: #000;
