I would like to know how to get data between date range in javascript
I have object array obj and variables sdate and edate,
how to get array object if the cdate falls between the range sdate and edate
function getdate(){
var finals=[];
var result = obj.orders.filter(e=>{
if(e.cdate < sdate && e.cdate > edate){
finals.push(e);
}
})
}
var obj={
orders:[
{id:1, mode: "xyz", orderid: 123, cdate: "2017-2-13 07:33:30"},
{id:2, mode: "abc", orderid: 456, cdate: "2018-4-20 06:10:30"},
{id:3, mode: "xyz", orderid: 768, cdate: "2020-8-10 08:00:00"}
]
}
var sdate="11-5-2020"
var edate="20-2-2021"
Expected Output
[
{id:3, mode: "xyz", orderid: 768, cdate: "2020-8-10 08:00:00"}
]
In your attemot you are comparing your sdate and edate with cdate node from the onjects in array. This will berform only string comparison, since both of them are strings. To perform Date comparison, you have to convert both of them into Date objects. Your cdate is a standard date object, so new Date() will retun the date object for the string.
But your sdate and edate are not valid date strings. So I have splitted them and created new date object using that. Comparing the date objects will provide you the expected result.
Also I have set hours of endDate to 23, 59, 59, 999. This is to ensure that if a date in array comes with the same date as end date, that should be filtered out. Because that is the maximum value for end date for the particular day.
Also you dont need to push finals.push(e) inside the filter function. Instead you could simply return the status of that comparison inside your filter. This will generate a new array. This will be your expected result.
Your logic for calculating the value inbetween two dates is wrong. i have corrected that aswell.
var sdate = "11-5-2020";
var edate = "20-2-2021";
var obj = {
orders: [
{ id: 1, mode: "xyz", orderid: 123, cdate: "2017-2-13 07:33:30" },
{ id: 2, mode: "abc", orderid: 456, cdate: "2018-4-20 06:10:30" },
{ id: 3, mode: "xyz", orderid: 768, cdate: "2020-8-10 08:00:00" }
]
}
function getdate() {
var finals = [];
const [sDay, sMonth, sYear] = sdate.split('-');
const [eDay, eMonth, eYear] = edate.split('-');
const startDate = new Date(sYear, +sMonth - 1, sDay);
const endDate = new Date(eYear, +eMonth - 1, eDay, 23, 59, 59, 999);
var result = obj.orders.filter(e => (new Date(e.cdate) >= startDate && new Date(e.cdate) <= endDate));
return result;
}
console.log(getdate());Please Note You can perform string comparison with dates if they are in standard ISO format. If your want to make use of that, you need to make the start and end date to iso format and perfrom comparison. So the filter statement will be
var result = obj.orders.filter(e => e.cdate >= startDate.toISOString() && e.cdate <= endDate.toISOString());
You have several issues
Wrong test for between: date >= sdate && date <= edate is what you need
If you cannot change the sdate, edate and the object dates, you can still format and still do string manipulation which is faster and safer than date manipulation due to timezones and daylight savings times
let obj={
orders:[
{id:1, mode: "xyz", orderid: 123, cdate: "2017-2-13 07:33:30"},
{id:2, mode: "abc", orderid: 456, cdate: "2018-4-20 06:10:30"},
{id:3, mode: "xyz", orderid: 768, cdate: "2020-8-10 08:00:00"}
]
}
const getyyyymmdd = str => {
const parts = str.split(" ")[0].split("-")
return parts[0].length === 2 ? `${parts[2]}-${parts[1].padStart(2, '0')}-${parts[0].padStart(2, '0')}` : `${parts[0].padStart(2, '0')}-${parts[1].padStart(2, '0')}-${parts[2]}`
}
function getdate(sdate,edate){
sdate = getyyyymmdd(sdate)
edate = getyyyymmdd(edate)
return obj.orders.filter(({cdate}) => {
cdate = getyyyymmdd(cdate);
return cdate >= sdate && cdate <= edate
})
}
console.log(getdate("11-5-2020","20-2-2021"))Alternatively if you can change either of the dates, you can add leading 0s to the object and swap the order of the start and end date
let obj={
orders:[
{id:1, mode: "xyz", orderid: 123, cdate: "2017-02-13 07:33:30"},
{id:2, mode: "abc", orderid: 456, cdate: "2018-04-20 06:10:30"},
{id:3, mode: "xyz", orderid: 768, cdate: "2020-08-10 08:00:00"}
]
}
function getdate(sdate,edate){
return obj.orders.filter(item => {
return item.cdate.split(" ")[0] >= sdate && item.cdate.split(" ")[0] <= edate
})
}
console.log(getdate("2020-05-11","2021-02-20"))You can get the desired result by first converting the string into Date object by passing the string in right format using helper function createDateObj.
Then using filter and get the result as
return arr.filter((o) => {
const date = new Date(o.cdate);
return date - start > 0 && end - start > 0;
})
var sdate = "11-5-2020";
var edate = "20-2-2021";
function createDateObj(str) {
const [a, b, c] = str.split("-");
return `${b}-${a}-${c}`;
}
function getdate(arr) {
const start = new Date(createDateObj(sdate));
const end = new Date(createDateObj(edate));
return arr.filter((o) => {
const date = new Date(o.cdate);
return date - start > 0 && end - start > 0;
});
}
var obj = {
orders: [
{ id: 1, mode: "xyz", orderid: 123, cdate: "2017-2-13 07:33:30" },
{ id: 2, mode: "abc", orderid: 456, cdate: "2018-4-20 06:10:30" },
{ id: 3, mode: "xyz", orderid: 768, cdate: "2020-8-10 08:00:00" },
],
};
console.log(getdate(obj.orders));
