3、goods.js代碼
var goods_id
var myTime //計數器
Page({
data: {
goodsInfo: null,
publisher: null,
auctionRecord: null,
clock: '',
changePrice: null //出價
},
onLoad(options) {
let goodsId = options.goodsid
//將id存起來給onshow用
goods_id = goodsId
//獲取商品信息
this.getGoodsInfo(goodsId)
//倒計時
this.countdown(goodsId)
},
onShow() {
this.getGoodsInfo(goods_id)
this.getAuctionRecord()
},
onUnload() {
//清楚計時器
clearInterval(myTime)
},
onHide() {
//清楚計時器
clearInterval(myTime)
},
//查詢所有商品
getGoodsInfo(goodsId) {
wx.cloud.database().collection('goods').doc(goodsId).get({
success: (res) => {
this.setData({
goodsInfo: res.data,
changePrice: res.data.current_price + 1
})
//根據發佈者id去用戶表中查詢商品發佈者信息
wx.cloud.database().collection('userInfo').doc(res.data.publisher_id).get({
success: (res) => {
this.setData({
publisher: res.data
})
}
})
}
})
},
//底部加減價格
addPrice() {
var price = this.data.changePrice
price++
this.setData({
changePrice: price
})
},
downPrice() {
var price = this.data.changePrice
if (price > this.data.goodsInfo.current_price + 1) {
price--
this.setData({
changePrice: price
})
} else {
wx.showToast({
title: '出價應當高於當前價!',
icon: 'none'
})
}
},
//競拍者出價
putPrice() {
//獲取出價
let price = this.data.changePrice
//獲取出價用戶
let userInfo = wx.getStorageSync('userInfo')
//獲取出價時間
let nowTime = new Date().getTime()
//轉化為時間格式
var util = require("../../util/time_transform.js")
let timeFormat = util.js_date_time(nowTime)
//彈窗確認
wx.showModal({
title: '確認出價',
content: '價高者得,競拍結束價高者可在競拍記錄中查看賣家聯繫信息,感謝您的參與!',
success: (res) => {
if (res.confirm) {
wx.showLoading({
title: '正在出價...',
})
//保存競拍記錄到資料庫
wx.cloud.database().collection('goodsAuctionRecord').add({

auctionTimeFormat: timeFormat
},
success: res => {}
}),
//更新當前價
wx.cloud.database().collection('goods').doc(goods_id).update({
data: {
current_price: price
}
})
let _this = this
setTimeout(function () {
wx.hideLoading({
success: (res) => {
//刷新頁面數據
_this.onShow()
}
})
}, 1000)
} else {
console.log('取消')
}
}
})
},
//獲取商品用戶競拍記錄
getAuctionRecord() {
wx.cloud.database().collection('goodsAuctionRecord').where({
goodsID: goods_id
}).get({
success: (res) => {
this.setData({
auctionRecord: res.data
})
}
})
},
//獲取競拍結束時間,並計算倒計時
countdown(goodsId) {
wx.cloud.database().collection('goods').doc(goodsId).get({
success: res => {
//取出競拍結束時間,精確到秒
let auctionEndtime = res.data.end_time
console.log(res)
//獲取當前系統時間,只精確到秒
var nowTime = new Date().getTime() / 1000
//剩餘時間總的秒數
var totalSecond = Math.floor(auctionEndtime - nowTime)
console.log('剩餘秒數', totalSecond)
//計算倒計時
this.doCountdown(totalSecond)
}
})
},
//計算商品倒計時
doCountdown(totalSecond) {
let _this = this
//每隔一秒執行一次代碼
myTime = setInterval(function () {
//如果競拍已經結束
if (totalSecond < 0) {
_this.setData({
clock: '已經截止'
})
clearInterval(myTime)
return
} else {
//執行計算
var time = _this.formatTime(totalSecond)
_this.setData({
clock: '剩餘' + time
})
}
totalSecond--;
}, 1000)
},
//倒計時時間格式化
formatTime(totalSecond) {
//剩餘天數
var day = Math.floor(totalSecond / 3600 / 24)
//n天後剩餘小時數
var hour = Math.floor(totalSecond / 3600 % 24)
//n天n小時後剩餘分鐘數
var min = Math.floor(totalSecond / 60 % 60)
//n天n小時n分鐘後剩餘秒數
var sec = Math.floor(totalSecond % 60)
return day + "天" + hour + "小時" + min + "分" + sec + "秒"
}
})
4、時間轉化js代碼
在util 下麵新建一個time_transform.js文件
//時間戳轉換成日期時間,傳入時間精確到毫秒
function js_date_time(unixtime) {
var date = new Date(unixtime)
var y = date.getFullYear();
var m = date.getMonth() + 1;
m = m < 10 ? ('0' + m) : m;
var d = date.getDate();
d = d < 10 ? ('0' + d) : d;
var h = date.getHours();
h = h < 10 ? ('0' + h) : h;
var minute = date.getMinutes();
var second = date.getSeconds();
minute = minute < 10 ? ('0' + minute) : minute;
second = second < 10 ? ('0' + second) : second;
return y + '-' + m + '-' + d + ' ' + h + ':' + minute + ':' + second;//年月日時分秒
// return y + '-' + m + '-' + d + ' ' + h + ':' + minute;
// return y + '-' + m + '-' + d;
}
module.exports = {
js_date_time: js_date_time
}
