var goods_id
var myTime //计数器
Page({
data: {
goodsInfo: null,
publisher: null,
auctionRecord: null,
clock: '',
changePrice: null //出价
},
onLoad(options) {
let goodsId = options.goodsid
//将id存起来给onshow用
goods_id = goodsId
//获取商品信息
this.getGoodsInfo(goodsId)
//倒计时
this.countdown(goodsId)
},
onShow() {

wx.cloud.database().collection('goods').doc(goodsId).get({
success: (res) => {
this.setData({
goodsInfo: res.data,
changePrice: res.data.current_price + 1
})
//根据发布者id去用户表中查询商品发布者信息
wx.cloud.database().collection('userInfo').doc(res.data.publisher_id).get({

var price = this.data.changePrice
if (price > this.data.goodsInfo.current_price + 1) {
price--
this.setData({
changePrice: price
})
} else {
wx.showToast({
title: '出价应当高于当前价！',
icon: 'none'
})
}
},
//竞拍者出价
putPrice() {
//获取出价
let price = this.data.changePrice
//获取出价用户
let userInfo = wx.getStorageSync('userInfo')
//获取出价时间
let nowTime = new Date().getTime()
//转化为时间格式
var util = require("../../util/time_transform.js")
let timeFormat = util.js_date_time(nowTime)
//弹窗确认
wx.showModal({
title: '确认出价',
content: '价高者得，竞拍结束价高者可在竞拍记录中查看卖家联系信息，感谢您的参与！',
success: (res) => {
if (res.confirm) {
wx.showLoading({

})
//保存竞拍记录到数据库
wx.cloud.database().collection('goodsAuctionRecord').add({

auctionTimeFormat: timeFormat
},
success: res => {}
}),
//更新当前价
wx.cloud.database().collection('goods').doc(goods_id).update({
data: {
current_price: price
}
})
let _this = this
setTimeout(function () {
wx.hideLoading({
success: (res) => {
//刷新页面数据
_this.onShow()
}
})
}, 1000)
} else {
console.log('取消')
}
}
})
},
//获取商品用户竞拍记录
getAuctionRecord() {
wx.cloud.database().collection('goodsAuctionRecord').where({
goodsID: goods_id
}).get({
success: (res) => {
this.setData({
auctionRecord: res.data

}
})
},
//获取竞拍结束时间，并计算倒计时
countdown(goodsId) {
wx.cloud.database().collection('goods').doc(goodsId).get({
success: res => {
//取出竞拍结束时间，精确到秒
let auctionEndtime = res.data.end_time
console.log(res)
//获取当前系统时间,只精确到秒
var nowTime = new Date().getTime() / 1000
//剩余时间总的秒数
var totalSecond = Math.floor(auctionEndtime - nowTime)
console.log('剩余秒数', totalSecond)
//计算倒计时
this.doCountdown(totalSecond)
}
})
},
//计算商品倒计时
doCountdown(totalSecond) {
let _this = this
//每隔一秒执行一次代码
myTime = setInterval(function () {
//如果竞拍已经结束
if (totalSecond < 0) {
_this.setData({
clock: '已经截止'
})
clearInterval(myTime)
return
} else {
//执行计算
var time = _this.formatTime(totalSecond)
_this.setData({
clock: '剩余' + time
})
}
totalSecond--;
}, 1000)
},
//倒计时时间格式化
formatTime(totalSecond) {
//剩余天数
var day = Math.floor(totalSecond / 3600 / 24)
//n天后剩余小时数
var hour = Math.floor(totalSecond / 3600 % 24)
//n天n小时后剩余分钟数
var min = Math.floor(totalSecond / 60 % 60)
//n天n小时n分钟后剩余秒数
var sec = Math.floor(totalSecond % 60)
return day + "天" + hour + "小时" + min + "分" + sec + "秒"
}
})
4、时间转化js代码
在util 下面新建一个time_transform.js文件
//时间戳转换成日期时间，传入时间精确到毫秒
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;//年月日时分秒
// return y + '-' + m + '-' + d + ' ' + h + ':' + minute;
// return y + '-' + m + '-' + d;
}
module.exports = {
js_date_time: js_date_time
