Data pass as objects as well as an array? - javascript

I'm developing a system for manage directors in group of companies. I need to filter directors for companies as assigned. After I pass data from controller to view, when selecting companies the filter shows incorrect results.
The above results will show when I console.log(this.directorships) those. I think it's because for single data it'll show as an array. But if those multiple it'll show as objects.
I'm looping those inside for loop as follows to print results.
for (let i = 0; i < this.directorships.length; i++) {
single_director = this.directorships[i].director_profile;
finalArray.push(single_director);
}
MyController.php
public function activeBoard($company_id){
$directorship = Directorship::with(['director_profile'])
->where('master_data_id',$company_id)
->get();
$active_directors = $directorship->where('active',1);
return $active_directors;
}
Can anyone please tell me what's the mistake I have done here? Or are there any methods to do what I expect?

It's hard to tell from the screenshots, but Objects in JavaScript are not iterable using a standard for loop, and don't have a length property by default. You should first check whether the directorships is an array, and then iterate or read suitably. For example:
let directorships_is_array = Array.isArray(directorships);
if(directorships_is_array) {
// ... loop through array
}
else {
// ... perform other function on object
}
There are a number of ways to iterate through an object, and get an objects length. The new for in loops can iterate through an object. For example:
for(let director in directorships) {
console.log(director);
}
You can also get the length of the Object using something like, let directors_length = Object.keys(directorships).length and then do something like this:
let number_of_directorships = Object.keys(directorships).length;
for(let i=0; i<number_of_directorships; i++) {
// ... iterate here
}

you need to use query like this you have initialize query before the condition
public function activeBoard($company_id){
$directorship = Directorship::where('master_data_id',$company_id)->where('active',1)->with('director_profile')->get();
return $directorship;
}

How can I dynamically index through datalayer tags in GTM?

I'm using the DuracellTomi datalayer plugin to push cart data from woocommerce to a GTM model to handle some tracking.
The DuracellTomi plugin pushes content to the transactionProducts[] array in the following format:
transactionProducts: Array[1]
0 : Object
category:""
currency:"USD"
id:8
name:"Test"
price:100
quantity:"1"
sku:8
I'd like to loop through this array and unstack it into three separate arrays, pricelist, skulist, and quantitylist. Currently I anticipate doing so as some variation on
//Get Product Information
if(stack = {{transactionProducts}}){
for(i = 0; i < stack.length; i++) {
if(stack.i.sku){
skulisttemp.i = stack.i.sku;
}
if(stack.i.price){
pricelisttemp.i = stack.i.price;
}
if(stack.i.sku){
quantitylisttemp.i = stack.i.quantity;
}
}
{{skulist}} = skulisttemp;
{{pricelist}} = pricelisttemp;
{{quantitylist}} = quantitylisttemp;
}
Obviously this is not going to work because of how the tag referencing is set up, but I'm wondering if anyone has dealt with this and knows what the best way to index through these arrays might be. (For those who don't know, the square bracket array call doesn't work with GTM variables and instead the . format is used instead.)
You would need to create 3 variable type custom javascript function that picks your required value from dataLayer and returns it in an array.
Something like
function(){
var products = {{transactionProducts}};
var skuArray = [];
for(i = 0; i < products.length; i++) {
if(products[i].sku){
skuArray.push(products[i].sku)
}
}
return skuArray
}
hope this helped you :)

delete a Object from an Array stored in localStorage on a specific condition?

I have stored certain information in localStorage like-
$localStorage.recent = [{'id':1,'name':'abc','is_availbale':1},{'id':2,'name':'xyz','is_availbale':1},{'id':3,'name':'pqrs','is_availbale':0}];
having another array which is only having id's of certain people like(array_second can have only those id's which are already there in
$localStorage.recent)-
array_second=['3'];
I want to delete those entries from $localStorage.recent which are corresponding to the id's in array_second. Expected output to be-
$localStorage.recent = [{'id':1,'name':'abc','is_availbale':1},{'id':2,'name':'xyz','is_availbale':1}];
You're just handling a standard array. The ngstorage library doesn't give you any additional functionality here.
For example:
$localStorage.recent = $localStorage.recent.filter((person) => {
return second_array.indexOf(person.id) !== -1;
});
This code may useful to you, written in javascript
var fullArr =[{'id':1,'name':'abc','is_availbale':1{'id':2,'name':'xyz','is_availbale':1},{'id':3,'name':'pqrs','is_availbale':0}];
var toDelArr = [1];
for(var i=0;i<fullArr.length;i++){
if(toDelArr[0] == fullArr[i].id){
fullArr.splice(i, 1);
}
}

Javascript search if LocalStorage variable exists

I am programming a chat system. I always make a Localstorage variable when a new chat is opened. Created like this:
localStorage.setItem("chat_"+varemail, data);
Now i want to check how many of them I have so something like:
"chat_"+... count.
How can I do this?
You'd grab the array of keys of the localStorage object, and use Array.filter to grab only the items starting with "chat_":
var length = Object.keys(localStorage).filter(function(key) {
return /^chat_.+/.test(key);
}).length;
Here's a JSFiddle
Try something like this, loop through all items in localStorage and match against your pattern
function getChatCount(){
var chatCount = 0;
for(item in localStorage){
if(item.indexOf('chat_') > -1) chatCount++;
}
return chatCount;
}
Local storage is based on key, value pairs. AFAIK, you wouldn't be able to retrieve all values with a certain prefix.
One potential solution would be to store an object that contains these. Based on your needs you could store the objects in an array or object and then retrieve the entire set and find the count.
For example:
var chats = { count: 0 };
chats["chat_"+varemail] = data;
chats.count += 1;
localStorage.setItem('chats', data);
Then if you want a count, you would retrieve the object:
var chats = localStorage.getItem('chats');
//chats.count would give you the count.
Although, this would mean you have to manually maintain the count variable when adding or removing data. If you don't need the indexing ability, you could add the chats to an array and store that.
EDIT: It is possible to find properties with a certain prefix, as seen in an answer to this question.
I would offer to convert to localStorage.setItem("chat", JSON.stringify(stack)), where stack is an array of chat objects. This way, you have access to an array of chats which you can count, search within, etc.
Something like:
var chatStore =
{
Count: function () {
var stack = JSON.parse(localStorage.getItem("chats"));
if (!stack)
return 0;
return stack.length;
},
Peek: function () {
var stack = JSON.parse(localStorage.getItem("chats"));
if (!stack)
stack = [];
if (stack.length > 0)
return stack.pop();
},
Push: function (token) {
var stack = JSON.parse(localStorage.getItem("chats"));
if (!stack)
stack = [];
stack.push(token);
localStorage.setItem("chats", JSON.stringify(stack));
},
// more methods to you might wish to implement: search, insert, etc.
}
// usage:
chatStore.Push(chatObject); // sets the last chat
chatStore.Peek(); // gets the last chat

access javascript array element by JSON object key

I have an array that looks like this
var Zips = [{Zip: 92880, Count:1}, {Zip:91710, Count:3}, {Zip:92672, Count:0}]
I would like to be able to access the Count property of a particular object via the Zip property so that I can increment the count when I get another zip that matches. I was hoping something like this but it's not quite right (This would be in a loop)
Zips[rows[i].Zipcode].Count
I know that's not right and am hoping that there is a solution without looping through the result set every time?
Thanks
I know that's not right and am hoping that there is a solution without
looping through the result set every time?
No, you're gonna have to loop and find the appropriate value which meets your criteria. Alternatively you could use the filter method:
var filteredZips = Zips.filter(function(element) {
return element.Zip == 92880;
});
if (filteredZips.length > 0) {
// we have found a corresponding element
var count = filteredZips[0].count;
}
If you had designed your object in a different manner:
var zips = {"92880": 1, "91710": 3, "92672": 0 };
then you could have directly accessed the Count:
var count = zips["92880"];
In the current form, you can not access an element by its ZIP-code without a loop.
You could transform your array to an object of this form:
var Zips = { 92880: 1, 91710: 3 }; // etc.
Then you can access it by
Zips[rows[i].Zipcode]
To transform from array to object you could use this
var ZipsObj = {};
for( var i=Zips.length; i--; ) {
ZipsObj[ Zips[i].Zip ] = Zips[i].Count;
}
Couple of mistakes in your code.
Your array is collection of objects
You can access objects with their property name and not property value i.e Zips[0]['Zip'] is correct, or by object notation Zips[0].Zip.
If you want to find the value you have to loop
If you want to keep the format of the array Zips and its elements
var Zips = [{Zip: 92880, Count:1}, {Zip:91710, Count:3}, {Zip:92672, Count:0}];
var MappedZips = {}; // first of all build hash by Zip
for (var i = 0; i < Zips.length; i++) {
MappedZips[Zips[i].Zip] = Zips[i];
}
MappedZips is {"92880": {Zip: 92880, Count:1}, "91710": {Zip:91710, Count:3}, "92672": {Zip:92672, Count:0}}
// then you can get Count by O(1)
alert(MappedZips[92880].Count);
// or can change data by O(1)
MappedZips[92880].Count++;
alert(MappedZips[92880].Count);
jsFiddle example
function getZip(zips, zipNumber) {
var answer = null;
zips.forEach(function(zip){
if (zip.Zip === zipNumber) answer = zip;
});
return answer;
}
This function returns the zip object with the Zip property equal to zipNumber, or null if none exists.
did you try this?
Zips[i].Zip.Count

arranging elements in to a hash array

I am trying to break a javascript object in to small array so that I can easily access the innerlevel data whenever I needed.
I have used recursive function to access all nodes inside json, using the program
http://jsfiddle.net/SvMUN/1/
What I am trying to do here is that I want to store these in to a separate array so that I cn access it like
newArray.Microsoft= MSFT, Microsoft;
newArray.Intel Corp=(INTC, Fortune 500);
newArray.Japan=Japan
newArray.Bernanke=Bernanke;
Depth of each array are different, so the ones with single level can use the same name like I ve shown in the example Bernanke. Is it possible to do it this way?
No, you reduce the Facets to a string named html - but you want an object.
function generateList(facets) {
var map = {};
(function recurse(arr) {
var join = [];
for (var i=0; i<arr.length; i++) {
var current = arr[i].term; // every object must have one!
current = current.replace(/ /g, "_");
join.push(current); // only on lowest level?
if (current in arr[i])
map[current] = recurse(arr[i][current]);
}
return join;
})(facets)
return map;
}
Demo on jsfiddle.net
To get the one-level-data, you could just add this else-statement after the if:
else
map[current] = [ current ]; // create Array manually
Altough I don't think the result (demo) makes much sense then.
