Remove all duplicate object elements from array - javascript

This one's been giving me problems for a week, cross my fingers one of you can help me here...
This application was built on Laravel and the front scaffolded using Vue.
Thing is I have an array of objects that is supposed to be sent to the backend in order for it to be stored in a database. Thing is this is an editor and the idea is not reload the page every time something is changed, so here comes my problem...
The way of getting the information is through window.postMessage(), so it seems the information lingers on even after saving, since the page behavior is for it to not reload, I have tried emptying the array after firing the save function. Now it works the first time because the array is empty so there's nothing to compare it to, it also works the second time, but from the third time on, it duplicates some of the objects inside and stores them in DB.
Here's my code:
saveNewSettings() {
//THIS IS THE ARRAY I NEED TO EMPTY (ALREADY DECLARED IN THE DATA OBJECT)
/* this.newItems = [
{ id="123", name="a", otherProps="someProps" },
{ id="456", name="ab, otherProps="someProps" },
{ id="789", name="c", otherProps="someProps" },
]
*/
//THIS IS THE AN EMPTY ARRAY I'M USING TO COMPARE LATER ON... (ALREADY DECLARED IN THE DATA OBJECT)
// this.newlyCreatedItems = [];
if ( !this.newlyCreatedItems.length ) {
this.newlyCreatedItems = this.newItems;
} else {
for ( let i = 0; i < this.newItems.length; i++ ) {
for ( let j = 0; j < this.newlyCreatedItems.length; j++ ) {
if ( this.newItems[i].id == this.newlyCreatedItems[j].id ) {
this.newItems.splice( i, 1 );
}
}
}
}
//THIS IS THE SERVICE I USE TO SEND THE INFO TO THE BACK END
//THIS ONE HAS BEEN IMPORTED FROM AN SERVICE FILE
settingsService.save( this.newItems )
.then(response => {
//WHAT TO DO AFTER THE RESPONSE GOES HERE
});
}
So here's the thing, firing the function for the first time, since it's the first, doesn't duplicate anything in the database... For the second time, it works well and it only saves the new item, from the third time on, it starts duplicating.
If you need me to elaborate more, just let me know, I thank you all in advance...

Quick and dirty using jQuery:
var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];
var uniqueNames = [];
$.each(names, function(i, el){
if($.inArray(el, uniqueNames) === -1) uniqueNames.push(el);
});

You tagged vue.js but this problem statement is more like from JavaScript side. Basically, You are doing shallow copy of the newItems array into the newlyCreatedItems array which causing the updation issue as both are referencing to the same pointer address.
You can resolve this issue by deep copying with the help of structuredClone() method.
Live Demo :
let newItems = [
{ id: "123", name: "a", otherProps: "someProps" },
{ id: "456", name: "ab", otherProps: "someProps" },
{ id: "789", name: "c", otherProps: "someProps" }
];
let newlyCreatedItems = [];
function saveNewSettings() {
if (!newlyCreatedItems.length ) {
newlyCreatedItems = structuredClone(newItems);
} else {
for ( let i = 0; i < newItems.length; i++ ) {
for ( let j = 0; j < newlyCreatedItems.length; j++ ) {
if ( newItems[i].id == newlyCreatedItems[j].id ) {
newItems.splice( i, 1 );
}
}
}
}
}
saveNewSettings();
console.log(newlyCreatedItems);
console.log(newItems);
console.log('-------');
saveNewSettings();
console.log(newlyCreatedItems);
console.log(newItems);

Group objects in array by property

I have just started to pick up coding seriously. :)
I came across a problem that seems too complicated for me.
How to group the following products by promotions type?
var data = [
{
name:'product1',
price:'40',
promotion:[
{
name:'Buy 3 get 30% off',
code:'ewq123'
},
{
name:'Free Gift',
code:'abc140'
}
]
},
{
name:'product2',
price:'40',
promotion:[
{
name:'Buy 3 get 30% off',
code:'ewq123'
}
]
},
{
name:'product3',
price:'40',
promotion:[
{
name:'Buy 3 get 30% off',
code:'ewq123'
}
]
},
{
name:'product4',
price:'40'
},
{
name:'product5',
price:'40',
promotion:[
{name:'30% off', code:'fnj245'}
]
},
{
name:'product6',
price:'0',
promotion:[
{
name:'Free Gift',
code:'abc140'
}
]
}
];
I would like to get result in the following format
result =[
{
name : 'Buy 3 get 30% off',
code: 'ewq123',
products: [
... array of products
]
},
{
name : '30% off',
code: 'fnj245',
products: [
... array of products
]
},
{
...
}
];
I am able to get a list of products by promotion code, but how can I make it generic?
function productHasPromo(product, promotion){
if(!product.hasOwnProperty('promotion')) return false;
var productPromo = product.promotion;
for(var i=0; i<productPromo.length; i++){
if(productPromo[i].code === promotion){
return true;
}
}
return false;
}
function groupProductByPromo(products, promotion){
var arr = [];
for(var i=0; i<products.length; i++){
if(productHasPromo(products[i], promotion)){
arr.push(products[i]);
}
}
return arr;
}
Explanation
You could write a function that loops through your array and search for the unique values within a specified property. That is easily done when working with simple data types, but can be done with more complex structures as arrays of objects (like in your example), using a helper grouping function.
Since you also need the output to be in a specific format after the grouping, we will have to work on a transformer also. This transformer will receive the original data and the unique values extracted by the grouping function, and will generate the desired output.
The following functions were used in the example:
Array.prototype.groupBy = function (property, grouping, transformer) {
var values = [];
this.forEach(function (item) {
grouping.call(this, item, property).forEach(function (item) {
if (!values.contains(property, item[property])) {
values.push(item);
}
});
});
return transformer.call(this, values);
};
Array.prototype.contains = function (key, value) {
return this.find(function (elm) {
return elm[key] === value;
});
};
function transformerFunction(values) {
this.forEach(function (item) {
if (!item.promotion) return;
item.promotion.forEach(function (promotion) {
values.forEach(function (option) {
if (option.code === promotion.code) {
if (option.products) {
option.products.push(item);
} else {
option.products = [item];
}
}
});
});
});
return values;
}
function groupingFunction(item, property) {
if (!item.promotion) return [];
var values = [];
item.promotion.forEach(function (promotion) {
if (!values.contains(property, promotion[property])) {
values.push(promotion);
}
});
return values;
}
Usage as follows:
var items = data.groupBy('code', groupFunction, transformFunction);
Example
Check the example i've prepared at jsfiddle
Welcome to the coding world. A lot of people start off with a problem by trying to write some code, then they wonder why it doesn't work and scratch their heads, don't know the basics of debugging it, and then post here to SO. They're missing the crucial first step in programming which is to figure out how you are going to do it. This is also called designing the algorithm. Algorithms are often described using something called pseudo-code. It has the advantage that it can be looked at and understood and established to do the right thing, without getting bogged down in all the mundane details of a programming language.
There are some algorithms that are figured out by some very smart people--like the Boyer-Moore algorithm for string matching--and then there are other algorithms that programmers devise every day as part of their job.
The problem with SO is that all too often someone posts a question which essentially about an algorithm, and then all the keyboard-happy code jockeys pounce it and come up with a code fragment, which in many cases is so contorted and obtuse that one cannot even see what the underlying algorithm is.
What is the algorithm you propose for solving your problem? You could post that, and people would probably give you reasonable comments, and/or if you also give an actual implementation that doesn't work for some reason, help you understand where you've gone wrong.
At the risk of robbing you the pleasure of devising your own algorithm for solving this problem, here's an example:
Create an empty array for the results.
Loop through the products in the input.
For each product, loop through its promotions.
Find the promotion in the array of results.
If there is no such promotion in the array of results, create a new one, with an empty list of products.
Add the product to the array of products in the promotion entry in the array.
In pseudo-code:
results = new Array // 1
for each product in products (data) // 2
for each promotion in promotions field of product // 3
if results does not contain promotion by that name // 4
add promotion to results, with empty products field // 5
add product to products field of results.promotion // 6
If we believe this is correct, we can now try writing this in JavaScript.
var result = []; // 1
for (var i = 0; i < data.length; i++) { // 2
var product = data[i];
var promotions = product.promotion;
for (var j = 0; j < promotions.length; j++) { // 3
var promotion = promotions[i];
var name = promotion.name;
var result_promotion = find_promotion_by_name(name);
if (!result_promotion) { // 4
result_promotion = { name: name, products: [], code: promotion.code };
result.push(result_promotion); // 5
}
result_promotion.products.push(name); // 6
}
}
This code is OK, and it should get the job done (untested). However, it is still a bit unreadable. It does not follow the pseudo-code very closely. It somehow still hides the algorithm. It is hard to be sure that it is completely correct. So, we want to rewrite it. Functions like Array#foreach make it easier to do this. the top level can simply be:
var result = [];
data.forEach(processProduct);
In other words, call the processProduct function for each element of data (the list of products). It will be very hard for this code to be wrong, as long as `processProduct is implemented incorrectly.
function processProduct(product) {
product.promotion.forEach(processPromotion);
}
Again, this logic is provably correct, assuming processPromotion is implemented correctly.
function processPromotion(promotion) {
var result_promotion = getPromotionInResults(promotion);
result_promotion.products.push(name);
}
This could hardly be clearer. We obtain the entry for this promotion in the results array, then add the product to its list of products.
Now we need to simply implement getPromotionInResults. This will include the logic to create the promotion element in the results array if it doesn't exist.
function getPromotionInResults(promotion) {
var promotionInResults = findPromotionInResultsByName(promotion.name);
if (!promotionInResults) {
promotionInResults = {name: promotion.name, code: promotion.code, products: []};
result.push(promotionInResults);
}
return promotionInResults;
}
This also seems demonstrably correct. But we still have to implement findPromotionInResultsByName. For that, we can use Array#find, or some equivalent library routine or polyfill:
function findPromotionInResultsByName(name) {
return result.find(function(promotion) {
return promotion.name === name;
});
}
The entire solution is thus
function transform(data) {
// Given a product, update the result accordingly.
function processProduct(product) {
product.promotion.forEach(processPromotion);
}
// Given a promotion, update its list of products in results.
function processPromotion(promotion) {
var result_promotion = getPromotionInResults(promotion);
result_promotion.products.push(name);
}
// Find or create the promotion entries in results.
function getPromotionInResults(promotion) {
var promotionInResults = findPromotionInResultsByName(promotion.name);
if (!promotionInResults) {
promotionInResults = {name: promotion.name, code: promotion.code, products: []};
result.push(promotionInResults);
}
return promotionInResults;
}
// Find an existing entry in results, by its name.
function findPromotionInResultsByName(name) {
return result.find(function(promotion) {
return promotion.name === name;
});
}
var result = [];
data.forEach(processProduct);
return result;
}
Ok, after a few hours of works, with lots of help online and offline, I finally made it works. Thanks for the people who has helped.
Please do comment if you have a more elegant solution, always love to learn.
For people who ran into similar problem:
Here is my solution
function groupProductsByPromo(data){
var result = [];
// filter only product with promotion
var productsWithPromo = data.filter(function(product){
return product.hasOwnProperty('promotions');
});
// create promotions map
var mappedProducts = productsWithPromo.map(function(product) {
var mapping = {};
product.promotions.forEach(function(promotion) {
mapping[promotion.code] = {
promotion: promotion
};
});
return mapping;
});
// reduce duplicates in promotion map
mappedProducts = mappedProducts.reduce(function(flattenObject, mappedProducts) {
for (var promoCode in mappedProducts) {
if (flattenObject.hasOwnProperty(promoCode)) {
continue;
}
flattenObject[promoCode] = {
code: promoCode,
name: mappedProducts[promoCode].promotion.name
};
}
return flattenObject;
}, {});
// add products to promo item
for(var promoCode in mappedProducts){
mappedProducts[promoCode].products = productsWithPromo.filter(function(product){
return product.promotions.some(function(promo){
return promo.code === promoCode;
});
});
result.push(mappedProducts[promoCode]);
}
return result;
}

AngularJS: Merge object by ID, i.e. replace old entry when IDs are identical

I am using Ionic with AngularJS and I am using a localForage database and AJAX via $http. My app has a news stream that contains data like this:
{
"feed":[
{
"id":"3",
"title":"Ein Hund",
"comments:"1"
},
{
"id":"2",
"title":"Eine Katze",
"comments":"2"
}
],
"ts":"20150907171943"
}
ts stands for Timestamp. My app saves the feed locally via localForage.
When the app starts it first loads the locally saved items:
$localForage.getItem("feed").then(function(val) { vm.feed = val; })
Then, it loads the new or updated items (ts < current timestamp) and merges both the old and new data:
angular.extend(vm.feed, response.data.feed);
Updated items look like this:
{
"feed":[
{
"id":"2",
"title":"Eine Katze",
"comments":"4"
}
],
"ts":"20150907171944"
}
That is, the comments count on feed item 2 has changed from 2 to 4. When I merge the old and new data, vm.feed has two items with id = 2.
Does angularjs has a built-in "merge by id" function, i. e. copy from source to destination (if it is a new element), or otherwise replace the old element? In case angularjs does not have such a function, what's the best way to implement this?
Thanks in advance!
angular.merge(vm.feed, response.data.feed);
// EDIT
Probably, it will not merge correctly, so you have to update all properties manually. Update ts property and then find your object with id and replace it.
There is no builtin, I usually write my own merge function:
(function(){
function itemsToArray(items) {
var result = [];
if (items) {
// items can be a Map, so don't use angular.forEach here
items.forEach(function(item) {
result.push(item);
});
}
return result;
}
function idOf(obj) {
return obj.id;
}
function defaultMerge(newItem, oldItem) {
return angular.merge(oldItem, newItem);
}
function mergeById(oldItems, newItems, idSelector, mergeItem) {
if (mergeItem === undefined) mergeItem = defaultMerge;
if (idSelector === undefined) idSelector = idOf;
// Map retains insertion order
var mapping = new Map();
angular.forEach(oldItems, function(oldItem) {
var key = idSelector(oldItem);
mapping.set(key, oldItem);
});
angular.forEach(newItems, function(newItem) {
var key = idSelector(newItem);
if (mapping.has(key)) {
var oldItem = mapping.get(key);
mapping.set(key, mergeItem(newItem, oldItem));
} else {
// new items are simply added, will be at
// the end of the result list, in order
mapping.set(key, newItem);
}
});
return itemsToArray(mapping);
}
var olds = [
{ id: 1, name: 'old1' },
{ id: 2, name: 'old2' }
];
var news = [
{ id: 3, name: 'new3' },
{ id: 2, name: 'new2' }
];
var merged = mergeById(olds, news);
console.log(merged);
/* Prints
[
{ id: 1, name: 'old1' },
{ id: 2, name: 'new2' },
{ id: 3, name: 'new3' }
];
*/
})();
This builds a Map from the old items by id, merges in the new items, and converts the map back to list. Fortunately the Map object will iterate on the entries in insertion order, according to the specification. You can provide your idSelector and mergeItem functions.
Thanks hege_hegedus. Based on your code, I've written my own and tried to use less loops to speed things up a bit:
function updateCollection(localCollection, fetchedCollection) {
angular.forEach(fetchedCollection, function(item) {
var append = true;
for (var i = 0; i < localCollection.length; i++) {
if (localCollection[i].id == item.id) {
// Replace item
localCollection[i] = item;
append = false;
break;
} else if (localCollection[i].id > item.id) {
// Add new element at the right position, if IDs are descending check for "< item.id" instead
localCollection.splice(i, 0, item);
append = false;
break;
}
}
if (append) {
// Add new element with a higher ID at the end
localCollection.push(item);
// When IDs are descending use .unshift(item) instead
}
});
}
There is still room for improvements, i. e. the iteration through all the objects should use binary search since all items are sorted by id.

Null Values in array of objects

I am creating objects when textbox having some values (using ng-blur and textbox.value!==undefined) and then putting these objects in an array (all working fine here).
When I click on checkbox (checkbox model bind with textbox ng-required) I need to delete that particular object having that textbox value.
I am using:
arr.splice(index,1);
to remove that particular object from array (by matching it's name like "monthly" or "quarterly" etc.), but it is creating null at that particular position.
for e.g. [object,object,object]
[
{name:"monthly",
amount:1000 },
{name:"quarterly",
amount:1200 },
{name:"yearly",
amount:1300 }
]
after removing all element it shows [] and when I add another new object it displays [3:object] and it's content as [null,null,null,object];
or
if I remove middle object say name:"quarterly", it shows [object,object] but after adding a new object it display array as [object,object,null,object] with length of array as 4.
Why is there null and how can I remove that from array. (don't want to iterate again to check null).
It is difficult to say why your code creates the null values without have a look to it.
But I can say you that it is not the expected behaviour.
You can see this example to get some inspiration:
var data = [
{name:"monthly",
amount:1000 },
{name:"quarterly",
amount:1200 },
{name:"yearly",
amount:1300 }
];
var newObjectToBeAdded = { name: "daily", amount:"100" }
function showObjects()
{
document.body.innerHTML += data + '<hr>';
}
function deleteObjectByName( objectName )
{
for( var i = 0; i < data.length; i++ )
{
if( data[ i ].name == objectName )
{
data.splice(i, 1);
}
}
}
function addObjectToData( newObject )
{
data.push( newObject );
}
showObjects();
deleteObjectByName( "quarterly" );
showObjects();
addObjectToData( newObjectToBeAdded );
showObjects();
Just to throw a guess out, maybe you are accidentally duplicating the array. Maybe in some point of your code you are doing something like this:
var new_array = original_array.splice( index );
Or creating the new array in the loop you use to find the target object, or using some kind of intermediate array, etc.
Hope it helps!
var arrayWithoutNulls = myArray.filter(function(val) {
if (val) {
return val;
}
});

How can get a count with nested objects with a certain property?

Okay so I'm using angular to get a json saved to my computer to recreate a github gradebook.
I can get the data with my $http request but for the love of me all I want is to get a count of the number of issues with the label "Not Yet".
Here is the javascript:
$http.get('/api/github/repos/issues/all_issues/00All.json')
.then(function(response) {
console.log(response.data[0]);
var counter = 0;
for(var index = 0; index < response.data.length; index++) {
if(response.data[index].labels[0].name == "Not Yet") {
counter++;
};
};
console.log(counter);
});
That's the latest try, I also tried using lodash to get it earlier:
$http.get('/api/github/repos/issues/all_issues/00All.json')
.then(function(response) {
console.log(response);
mile.notYet.width = _.forEach(response.data, function(n){
var counter = 0;
if(_.result(_.find(n.labels[0], 'name')) == "Not Yet") {
counter++;
}
console.log(counter);
counter = ((counter/10) * 100) + '%';
});
});
This is a bit of the json data:

As you can see the labels property is an object, nested in an array, nested in an object, nested in an array, real lovely. Putting labels[0] results in an error for me each time and doesn't get me a count. Can anybody tell me where I'm messing up please? Thank you!
If you need a solution that includes lodash, which is much more performant than the native high order functions then you can try this solution below:
var size = _(response.data)
.pluck('labels')
.flatten()
.where({ name: 'Not Yet' })
.size();
UPDATE:
If you want it to be more reusable, you can save a reference for a cloned chained sequence and simply supply another array for that cloned sequence.
var data1 = [/*array from data1*/];
var data2 = [/*array from data2*/];
var notYetSequence = _(data1)
.pluck('labels')
.flatten()
.where({ name: 'Not Yet' });
notYetSequence.size(); // returns data 1 count
notYetSequence.plant(data2).size(); // returns data 2 count
You don't need lodash for the task
var cnt = response.data
.map(function(i) { return i.labels; })
// here we extract labels object only (and get an array of arrays of objects)
.map(function(i) { return i.filter(function(l) { return l.name == 'Not yet'; }).length; })
// then for every nested array we return a number of items with
// Not Yet names (and get an array of numbers)
.filter(function(c) { return c > 0; })
// then we filter issues that don't have one (and still get an array of numbers)
.length;
// and finally get length (which is a number)
As a comparison, a plain for loop looks like:
var data = response.data;
var count = 0;
var re = /not yet/i;
for (var a, i=0, iLen=data.length; i<iLen; i++) {
a = data[i].labels;
for (var j=0, jLen=a.length; j<jLen; j++) {
if (re.test(a[j].name)) ++count;
}
}
So really not a lot of code either way, the for loop will be compatible with every browser ever (though using xmlHTTPRequest means at least ed 3+) and fastest… untested of course. ;-)

Delete an element inside a JSON array by value with jQuery

Part of my json Array
var videos = $j.parseJSON('
[
{ "privacy":"public",
"id":"1169341693" },
{ "privacy":"private",
"id":"803641223" },
{ "privacy":"public",
"id":"1300612600" }, ......
When I console.log the element I'm getting
[Object, Object, Object, …]
0: Object
privacy: "public"
id: "1169341693"
1: Object
privacy: "private"
id: "803641223"
2: Object
privacy: "public"
id: "1300612600"
I also have a unique id I want to search for
var uniqueId = 803641223;
I want to find, in my videos array, the right id, and delete that whole array element. So In that case, I want my final videos array to contain only 2 object, instead of 3 :
var videos = $j.parseJSON('
[
{ "privacy":"public",
"id":"1169341693" },
{ "privacy":"public",
"id":"1300612600" }, ......
My problem is how to get in the array to do my splice. I prefer to do it with jQuery
Any help please?
You can use grep :
videos = $.grep(videos, function(e) { return e.id!='803641223' });
In vanilla JavaScript you could have used the similar filter function but it's not supported by IE8.
Please note that videos is a JavaScript array, it's not a JSON array, even if it was made by parsing a JSON string.
A non-jQuery solution that modifies the array in place:
var uniqueId = 803641223;
var videos = [
{ "privacy":"public",
"id":"1169341693" },
{ "privacy":"private",
"id":"803641223" },
{ "privacy":"public",
"id":"1300612600" }
];
function cleaner(arr, id) {
for (var i = 0; i < videos.length; i++) {
var cur = videos[i];
if (cur.id == uniqueId) {
arr.splice(i, 1);
break;
}
}
}
cleaner(videos, uniqueId);

Note that this modifies the original array in place, such that the original videos array will have the items you want, and the one that matched the uniqueId will be gone (forever). So it depends on whether you want to be able to access the original array ever again, or are okay with modifying it.
It just loops through the elements of the array, compares the item's id property to the uniqueId value, and splices if they match. I use break; immediately after the splice because you seem to imply that the uniqueId can/should only appear once in the array since it's...unique.
Hello you can remove element with javascript splice function...
videos.items.splice(1, 3); // Removes three items starting with the 2nd,
It worker for me.
arrList = $.grep(arrList, function (e) {
if(e.add_task == addTask && e.worker_id == worker_id) {
return false;
} else {
return true;
}
});
It returns an array without that object.
Hope it helps.
