本文实例为大家分享了微信小程序云开发实现增删改查的具体代码，供大家参考，具体内容如下
首先按照微信小程序官方提示创建一个快速云开发小程序
大家可以点击此处下载源代码
实现效果如下：
在miniprogram->index的下修改下面三个文件
index.js如下：
Page({
data: {
id: '',//修改用来保存_id
iSshow: true,
inpVal: '',
inp2Val: '',
inp3Val: '',
list: []
},
onLoad: function () {
var that = this
that.getUserMsg()//读取信息
},
//获取文本框内容
getName(e) {
this.setData({
inpVal: e.detail.value
})
},
getAge(e) {
this.setData({
inp2Val: e.detail.value
})
},
getCreated(e) {
this.setData({
inp3Val: e.detail.value
})
},
//获取信息
getUserMsg() {
var that = this
const db = wx.cloud.database()
db.collection('datalist').get({
success: function (res) {
console.log(res)
that.setData({
list: res.data
})
}
})
},
//添加信息
setUserMsg() {
var that = this
const db = wx.cloud.database()
db.collection('datalist').add({
data: {
name: that.data.inpVal,
age: that.data.inp2Val,
created: that.data.inp3Val
},
success: function (res) {
console.log(res)
that.setData({
inpVal: "",
inp2Val: "",
inp3Val:""
})
console.log(that.data.inpVal + '--' + that.data.inp2Val + '--' + that.data.inp2Val)
that.getUserMsg()
}
})
},
//删除信息
delUserMsg(e) {
var that = this
const db = wx.cloud.database()
var id = e.currentTarget.dataset.id
db.collection('datalist').doc(id).remove({
success: function (res) {
console.log(res)
that.getUserMsg()
}
})
},
//修改回显
changeMsg(e) {
var that = this
var id = e.currentTarget.dataset.id
const db = wx.cloud.database()
db.collection('datalist').doc(id).get({
success: function (res) {
that.setData({
inpVal: res.data.name,
inp2Val: res.data.age,
inp3Val:res.data.created,
show: false,
id: res.data._id
})
}
})
},
//更新提交
updetMsg(e) {
var that = this
var id = e.currentTarget.dataset.id
const db = wx.cloud.database()
db.collection('datalist').doc(id).update({
data: {
name: that.data.inpVal,
age: that.data.inp2Val,
created:that.data.inp3Val
},
success: function (res) {
that.getUserMsg()
that.setData({
inpVal: '',
inp2Val: '',
inp3Val:'',
show: true
})
}
})
},
})
index.wxml如下：
<view class="container">
<view class='box' style='background:#FFFFFF'>
<label>姓名:</label>
<input data-value='{{inpVal}}' bindinput='getName' value='{{inpVal}}'></input>
</view>
<view class='box' style='background:#FFFFFF;margin-top:1rpx;'>
<label>年龄:</label>
<input data-value='{{inpVal}}' bindinput='getAge' value='{{inp2Val}}'></input>
</view>
<view class='box' style='background:#FFFFFF;margin-top:10rpx;'>
<label>手机号:</label>
<input data-value='{{inpVal}}' bindinput='getCreated' value='{{inp3Val}}'></input>
</view>
<button wx:if='{{show}}' bindtap='setUserMsg'>提交</button>
<button wx:if="{{!show}}" data-id="{{id}}" bindtap='updetMsg'>确认修改</button>
</view>
<view class='infoMsg'>
<view>
<label>姓名</label>
<label>年龄</label>
<label>手机号</label>
<label>操作</label>
</view>
<view wx:for="{{list}}">
<label>{{item.name}}</label>
<label>{{item.age}}</label>
<label>{{item.created}}</label>
<label>
<text data-id='{{item._id}}' bindtap='changeMsg'>修改</text>
</label>
</view>
</view>
index.wxss如下：
page {
background: #f6f6f6;
display: flex;
flex-direction: column;
justify-content: flex-start;
font-size: 30rpx;
}
.box{
width: 90%;
display: flex;
background: grey
}
button{
width: 90%;
height: 40px;
line-height: 40px;
margin-top: 20rpx;
background:#ffffff;
}
.infoMsg{
width: 90%;
margin: auto;
margin-top: 20rpx;
border: 1rpx solid #e2e2e2;
font-size: 28rpx;
}
.infoMsg view{
display: flex;
border-top: 1rpx solid #e2e2e2;
}
.infoMsg view>label{
flex: 1;
height: 80rpx;
line-height: 80rpx;
text-align: center;
overflow: hidden;
text-overflow: ellipsis;
white-space: nowrap;
}
.infoMsg view>label:not(:first-child){
border-left: 1rpx solid #e2e2e2;
}
.infoMsg view>label text{
margin-right: 10rpx;
border: 1rpx solid #e2e2e2;
}
