I want to merge some of the phonenumber data like 2555973055799 and 2555974235764, I the for example: they both have objects with date:2022-02-19 so, the resultant object after merging should be like:
{
"firstTime": "11:33:53",
"count": 149,
"date": "2022-02-19"
},
count should be sum of both objects from phonenumbers ad firstTime should be time which is first. and uid, phone number should be concatinated, lastTime should be which is greater of two times?
The remaining phonenumbers data should be unchanged, only these two objects data should be merged,
How should I do that?
can anyone please help with this?
CodePudding user response：
I am not sure if i understand your question correctly, but let's give it a try.
So, you would like to merge datas according to the date of usage. If 2 or more json objects was used on the same date, then you would like to to see the date, count and first time of use of these datas?
EDIT:
So, i created a prototype.
Maybe it is a little bit complicated solution, but i think it is good for a start. I separated every object with usage data, then i looked for date duplicates, i stored both uid and the same date. Then i looked up for the count's and compared the firstTime datas and everything stored in the result variable.
Check console log for result.
var result = [] // we will store the result here
var dataWithUsage = [];
for (var i in obj) // iterate thru every data
if (obj[i].usage) // if data has usage property
{
dataWithUsage.push(obj[i]) // separate it from the main data structure
}
// console.log(dataWithUsage)
var usages = [] // we will collect every usage here
dataWithUsage.forEach(data => {
// console.log(data.usage, data.uid)
data.usage.forEach(element => {
usages.push({ date: element.date, uid: data.uid })
});
});
// console.log(usages)
// we will compare every usage and we try to do it only once
for (let i = 0; i < usages.length; i ) {
for (let j = i 1; j < usages.length; j ) {
// console.log(usages[i], "vs" , usages[j])
if (usages[i].date == usages[j].date) {
result.push({ date: usages[i].date, uid1: usages[i].uid, uid2: usages[j].uid })
}
}
}
// at this point in the results we have our uid's with dates. Now we can do the data merge
result.forEach(element => {
var uid1Index = dataWithUsage.findIndex(object => object.uid == element.uid1)
var uid2Index = dataWithUsage.findIndex(object => object.uid == element.uid2) // we got the 2 objects for data merge
var count = 0
var firstTime
let usageIndexofuid1 = dataWithUsage[uid1Index].usage.findIndex(elem => elem.date == element.date)
let usageIndexofuid2 = dataWithUsage[uid2Index].usage.findIndex(elem => elem.date == element.date)
count = dataWithUsage[uid1Index].usage[usageIndexofuid1].count dataWithUsage[uid2Index].usage[usageIndexofuid2].count
// console.log(dataWithUsage[uid1Index].usage[usageIndexofuid1].firstTime, dataWithUsage[uid2Index].usage[usageIndexofuid2].firstTime)
// console.log(dataWithUsage[uid1Index].usage[usageIndexofuid1].firstTime > dataWithUsage[uid2Index].usage[usageIndexofuid2].firstTime)
firstTime = ((dataWithUsage[uid1Index].usage[usageIndexofuid1].firstTime < dataWithUsage[uid2Index].usage[usageIndexofuid2].firstTime) ? dataWithUsage[uid1Index].usage[usageIndexofuid1].firstTime : dataWithUsage[uid2Index].usage[usageIndexofuid2].firstTime)
// console.log(firstTime,"fistTime")
// console.log(count,"count")
element.count = count
element.firstTime = firstTime
});
console.log("result")
console.log(result)
