}else{z['valid_value_BLE']=z.valid_value;}
delete z.valid_value; return z;

How can i sort array with objects which have property with another array of objects but not with ES6 [duplicate]

This question already has answers here:
Sort nested array of object in javascript
(4 answers)
Closed 3 years ago.
I have this kind of array with objects. In each object except properties i have another array with objects called "secondary_fields". I need to access the last element in the secondary_fields array (secondary_fields[3]) where i have value of when it is created and after that to sort all of the objects
by the date time based on the value inside for example "2020-01-13 17:42:51";
But not with ES6 because i am using old platform where the ES6 version of Java Script is not supported
let arr =
[
{
"external": false,
"link": "--",
"direct": false,
"display_field": "new best article",
"id": "kb_knowledge:33",
"secondary_fields": [
{
"display_value": "Test Admin",
"name": "author",
"label": "Author",
"type": "reference",
"value": "xx"
},
{
"display_value": "25",
"name": "sys_view_count",
"label": "View count",
"type": "integer",
"value": "25"
},
{
"display_value": "2020-01-13 09:44:54",
"name": "sys_updated_on",
"label": "Updated",
"type": "glide_date_time",
"value": "2020-01-13 17:44:54"
},
{
"display_value": "2020-01-13 09:42:51",
"name": "sys_created_on",
"label": "Created",
"type": "glide_date_time",
"value": "2020-01-13 17:42:51"
}
],
},
{
"external": false,
"link": "--",
"direct": false,
"display_field": "How to connect the iPod to Wi-Fi",
"id": "kb_knowledge:11",
"secondary_fields": [
{
"display_value": "John",
"name": "author",
"label": "Author",
"type": "reference",
"value": "xxnnx"
},
{
"display_value": "16",
"name": "sys_view_count",
"label": "View count",
"type": "integer",
"value": "16"
},
{
"display_value": "2019-12-18 08:18:08",

"type": "glide_date_time",
"value": "2019-10-21 19:27:22"
}
],
}
]

You can make use of the array method's sort method and sort on display_value.
arr.sort(function(a, b) {
return new Date(a.secondary_fields[3].display_value) - new Date(b.secondary_fields[3].display_value)
})
Edit
Or I guess in your case,
return new Date(b.secondary_fields[3].display_value) - new Date(a.secondary_fields[3].display_value)

let arr =
[
{
"external": false,
"link": "--",
"direct": false,
"display_field": "new best article",

How to return a childobject from json with lodash?

Suppose I have the following json file and I would like to return the 'existing.primaryBundle.products' array preferrably with lodash:
{
"existing": {
"hasPlatinum": false,
"primaryBundle": {
"id": "2008",
"name": "TV - Entertainment, Sport",
"products": [
{
"name": "Entertainment",
"id": "100",
"price": 2600,
"gifted": false
},
{
"name": "Sport",
"id": "107",
"price": 2500,
"gifted": false,
"swappableProducts": [
{
"name": "Movies",
"id": "105",
"price": 2000,
"gifted": false
}
]
}
]
},
"extrasBundle": {
"id": "131",
"name": "Optional Extras - MUTV (Sports), LFCTV (Sports), Chelsea TV (Sports)",
"products": [
{
"name": "MUTV (Sports)",
"id": "665",
"price": 0,
"gifted": false
},
{
"name": "LFCTV (Sports)",
"id": "666",
"price": 0,
"gifted": false
},
{
"name": "Chelsea TV (Sports)",
"id": "667",
"price": 0,
"gifted": false
}
]
}
}
}
I have tried lodash and use this statement:
list2 = _.pick(existing,'primaryBundle.products')
But this returns an error and not the wanted result. How can I select this products array?

you could use _.get(nameOfObject, 'existing.primaryBundle.products') of course you would need to name your object like I've done below with sampleObject;
check out the lodash docs too
const sampleObject = {
"existing": {
"hasPlatinum": false,
"primaryBundle": {
"id": "2008",
"name": "TV - Entertainment, Sport",
"products": [{
"name": "Entertainment",
"id": "100",
"price": 2600,
"gifted": false
}, {
"name": "Sport",
"id": "107",
"price": 2500,
"gifted": false,
"swappableProducts": [{
"name": "Movies",
"id": "105",
"price": 2000,
"gifted": false
}]
}]
},
"extrasBundle": {
"id": "131",
"name": "Optional Extras - MUTV (Sports), LFCTV (Sports), Chelsea TV (Sports)",
"products": [{
"name": "MUTV (Sports)",
"id": "665",
"price": 0,
"gifted": false
}, {
"name": "LFCTV (Sports)",
"id": "666",
"price": 0,
"gifted": false
}, {
"name": "Chelsea TV (Sports)",
"id": "667",
"price": 0,
"gifted": false
}]
}
}
}
console.log(_.get(sampleObject, 'existing.primaryBundle.products'));

The main reason why it returns an error is because existing is not a global scoped object, you have to assign object to some variable like const obj = {...} and then pass the parameter to _pick method as obj.existing, yet I don't see a reason to use lodash in here, you can just reference the path to that object directly.

I and not able decode
"categorySpecificInfoV1": {
"keySpecs": [
"Passport Holder",
"Passport Wallet"
],
I have tried json_decode. This gives error
Warning: json_decode() expects parameter 1 to be string, array given.
$keySpecs=$product['categorySpecificInfoV1']['keySpecs'];
$ar = json_decode($keySpecs,true);
I am new to PHP, how can I print the keyspecs from keyspecs array?

The warning is pretty clear. You need to pass the entire string you obtained from Flipkart into the json_decode() function.
See Documentation
$ar = json_decode($flipkart_result, true);
print_r($ar); //to check the array.
print_r($ar['categorySpecificInfoV1']['keySpecs']);
This should do. Post more information if this does not help.

Knockout JS changing my viewmodel creation to use mapping pulgin

I am relatively new to Knockout.js and have a question regarding the creating of the view model.
What I am currently doing is:
viewModel = {
Menu: ko.observableArray(ko.utils.parseJson(data)),
editMenu: function (menu) {
ko.applyBindings(menu, document.getElementById("MenuCategories"));
$("#MenuCategories").bPopup();
}
There is more than one function, but trying to keep it short.
What I want to do is use the mapping plugin because my json data that I am using contains arrays of objects with each object containing an array and each object in that array also contains an array. What the JSON looks like:
[
{
"Id": 1,
"Name": "Test 5",
"Description": "Testing menu",
"BeveragesMenu": false,
"Active": true,
"Categories": [
{
"Id": 1,
"Name": "Test 1",
"Active": true,
"MenuItems": [
{
"Id": 1,
"Name": "Food",
"Description": "2 Eggs and Bread",
"Price": 50,
"DateBased": false,
"PriceOnRequest": false,
"DateFrom": null,
"DateTo": null,
"Active": true
}
]
},
{
"Id": 2,
"Name": "Test 2",
"Active": true,
"MenuItems": [
]
},
{
"Id": 1004,
"Name": "test",
"Active": true,
"MenuItems": [
]
},
{
"Id": 1005,
"Name": "Test 4",
"Active": true,
"MenuItems": [
]
}
]
},
{
"Id": 92,
"Name": "Test 4",
"Description": "",
"BeveragesMenu": false,
"Active": false,
"Categories": [
{
"Id": 1006,
"Name": "Test 1",
"Active": true,
"MenuItems": [
{
"Name": "Test",
"Description": "",
"Price": "",
"DateBased": false,
"PriceOnRequest": false
}
]
}
]
},
{
"Id": 93,
"Name": "Test 6",
"Description": "",
"BeveragesMenu": false,
"Active": false,
"Categories": [
]
},
{
"Id": 94,

},
{

"Categories": [
{

}
]
},
{

Sorry for the long JSON code paste.
So now I am running into problems when updating certain parts of the objects within arrays withing objects etc.
So I taught that the mapping plugin might solve my problem as it creates all arrays as observable and I am assuming that is my problem.
So I tried:
viewModel = {
Menu: ko.mapping.fromJSON(ko.utils.parseJson(data)),
//Menu: ko.observableArray(ko.utils.parseJson(data)),
editMenu: function (menu) {
ko.applyBindings(menu, document.getElementById("MenuCategories"));
$("#MenuCategories").bPopup();
},
But then none of my binding are working and I can't seem to find the cause, any advice or tips on this matter would be appreciated.
Here is a Fiddle of all the things I have tried. http://jsfiddle.net/armandvdwalt/pjJc2/3/
Thanks

Try this fiddle, I switched the order of the resources. You were referencing the mapping plugin before knockout which was generating a script error about not recognizing "ko." Also, you don't need to use ko.utils.parseJson when using fromJSON, as fromJSON expects JSON as an argument.
