this.validator is not a function with formarray. Angular2 - javascript

I'm working on a page which has a nested Formarray.
constructor(private fb: FormBuilder) {
this.buildForm();
}
private buildForm() {
this.trialBudgetForm = this.fb.group({
clients: this.fb.array([])
})
}
addCustomer() {
this.clients.push(this.initCustomer());
}
initCustomer() {
return this.fb.group({
earnedIncomes: this.fb.array([this.initIncome()]),
thirtyAndOneThirdYN: [],
thirtyYN: [],
earnedIncomeExpenseType: [],
earnedIncomeExpense: [],
dependentCareExpense: []
})
}
initIncome() {
return this.fb.group(new ScrAmountType());
}
ngOnInit() {
this.populateData();
}
populateData() {
const clients = this.TrialBudgetData.clients;
const customerFGs = clients.map(customer => this.fb.group({
earnedIncomes: this.populateIncome(customer.earnedIncomes),
thirtyAndOneThirdYN: [this.utilService.YNConvert(customer.thirtyAndOneThirdYN)],
thirtyYN: [this.utilService.YNConvert(customer.thirtyYN)],
earnedIncomeExpenseType: [customer.earnedIncomeExpenseType],
earnedIncomeExpense: [customer.earnedIncomeExpense],
dependentCareExpense: [customer.dependentCareExpense]
}));
const customerFormArray = this.fb.array(customerFGs);
this.trialBudgetForm.setControl('clients', customerFormArray);
}
for demo purpose, i didn't post the entire ts file, coz there are almost 600 lines. But i can provide more detail if needed.
here's the html page (also only a snippet)

I have been trying to debug this for couple days now. The issue happens after constructor executed and before ngOnInit was called. this error only occur when I added more than one customer, and come back to this page. (adding customer won't cause any problem, only when I comeback to this page that's when the error this.validator is not a function is shown.
It's strange because the error happen between constructor and ngOnInit, and populateData is called in ngOnInit, which means error occured before the page know how many customers will I load. But if only the error occur because I add more than one customer, it seems that applicaiton has to get that info within constructor, in which i didn't load the data yet.
Update 1: Sept 25 3:39PM EST
updated with populateData function
Update 2: full stack error: Sept 25 4:09PM EST

Update 3 question closed: thanks to #yurzui's comment
I just realized that the architecture is messed up for this page. This component has a parent which only has (current component selector) in its template. The two component has exactly the same name just under different folder. The parent is at /trial-budget and children is at /trial-budget/trial-budget-main. The TrialBudgetComponent.toFromGroup is actually a function inside the parent. For some reason, it's being called inside ngInit instead of constructor. Still haven't figure out why error only happen with 2 customer.
But lesson learned:
1. read error message carefully especially first and last couple lines. I didn't read the last line.
2. always construct form inside constructor and populate data inside ngOnInit()

JS Script crashes after temporaryURL is created with livewire

Does anyone know, How to resolve this issue of the crashed javascript script?
I am using 2 checkboxes to load some DOM.
1st checkbox is to expand textarea with the CKEditor script which is loaded with the JS but I have a wire model to send data to the controller.
Here is HTML for 1st checkbox:
<div class="form-group mt-25 d-flex flex-row">
<label class="checkbox-container form-group__label">
{{ __('Extended description') }}
<input type="checkbox" name="extended-description-checkbox" id="extended-description-checkbox" class="checkbox">
<span class="checkmark"></span>
</label>
</div>
<div class="form-group mt-25 cke d-none" id="extended-description-checkbox-div">
<label class="form-group__label" for="extended-description">{{ __('Extended description') }}</label>
<textarea wire:ignore.self wire:model.debounce.250ms.defer="extendedDescription" name="extended-description" id="extended-description" cols="30" rows="10"></textarea>
</div>
2nd checkbox is also handled with the JS and has a temporary URL method since the expanded DOM element should contain uploaded images for the gallery.
Here is HTML of the 2nd checkbox:
<div class="form-group mt-25 d-flex flex-row">
<label class="checkbox-container form-group__label">
{{ __('Use default images') }}
<input type="checkbox" name="use-default-images" id="use-default-images" class="checkbox">
<span class="checkmark"></span>
</label>
</div>
<div class="d-none" id="use-default-images-div">
<div class="form-group mt-25">
<label class="form-group__label">{{ __('Service images') }}</label>
<div class="form-group__uploaded-images">
#if ($additionalImages)
#foreach($additionalImages as $image)
<img src="{{ $image->temporaryUrl() }}" alt="Temporary image">
#endforeach
#endif
</div>
</div>
<div class="custom-file ml-auto">
<button type="button" class="ml-auto styled-link">{{ __('Add images') }}</button>
<div class="row mt-25">
<div class="col-4 col-md-8"></div>
<div class="col-8 col-md-4">
<input wire:ignore.self wire:model.defer="additionalImages" type="file" multiple>
#error('images.*') {{ $message }} #enderror
</div>
</div>
</div>
</div>
Here are the scripts for expanding of the both DOM elements:
const extendedCheckbox = document.querySelector('#extended-description-checkbox');
const extendedDiv = document.querySelector('#extended-description-checkbox-div');
extendedCheckbox.addEventListener('change', function() {
if(extendedCheckbox.checked) {
extendedDiv.classList.remove('d-none');
} else {
extendedDiv.classList.add('d-none');
}
});
const defaultImagesCheckbox = document.querySelector('#use-default-images');
const defaultImagesDiv = document.querySelector('#use-default-images-div');
defaultImagesCheckbox.addEventListener('change', function() {
if(defaultImagesCheckbox.checked) {
defaultImagesDiv.classList.remove('d-none');
} else {
defaultImagesDiv.classList.add('d-none');
}
});

Getting a HTML select value and and input value from submit angular 6

Angular JS Multiple ngRepeat

I'm trying to do the following : When you click on "Add Package" its pushes to an array a package where I can specify e.g. Package one, but within that I want to push multiple items (products) "Add Item". The problem is when I create a new package it works, but the items in each package is the same so when I add more to either dynamic package the items within is the same. I assume that's because the array is the same each time, how to I track that by index?
HTML:
<div class="col-12 order-box" ng-repeat="orderpackage in orderproductspackages track by $index">
<div class="col-12">
<label for="name_{{$index}}">Package Name</label>
<input type="text" ng-model="orderpackage.orderpackagename" name="name_{{$index}}" required>
</div>
<div class="col-12" ng-repeat="ordercontent in orderproductscontents track by $index">
<div class="col-2">
<label for="name_{{$index}}">Product</label>
<select ng-model="ordercontent.ordercontentname" name="name_{{$index}}" ng-change="onProductChange(ordercontent.ordercontentname,$index)">
<option ng-repeat="product in productResponse | orderBy:'productname'" value="{{product.productname}}">{{product.productname}}</option>
</select>
</div>
<div class="col-2">
<label for="name_{{$index}}">Quantity</label>
<input type="text" ng-model="ordercontent.ordercontentquantity" name="name_{{$index}}" ng-keyup="onProductChange(ordercontent.ordercontentname,$index)" required>
</div>
<div class="col-2">
<label for="name_{{$index}}">Price</label>
<input type="text" ng-model="ordercontent.ordercontentprice" name="name_{{$index}}" ng-change="onPriceChange(ordercontent.ordercontentname,$index)" disabled required>
</div>
<div class="col-2">
<label for="name_{{$index}}">Per {{ordercontent.ordercontentmeasurement}}</label>
<input type="text" ng-model="ordercontent.ordercontentpriceper" name="name_{{$index}}" disabled required>
</div>
<div class="col-2">
<label for="name_{{$index}}">Total</label>
<input type="text" ng-model="ordercontent.ordercontenttotal" name="name_{{$index}}" required disabled>
</div>
<div class="col-2">
<label for="name_{{$index}}">Options</label>
<a class="button critical small" ng-click="removeOrderContent($index)"><span class="fa fa-minus"></span> Remove</a>
</div>
</div>
<div class="col-12 m20-top p15 text-center add-api" ng-click="addOrderContent()">
<span class="fa fa-plus"></span> Add Item</a>
</div>
</div>
<div class="col-12 m20-top p15 text-center add-api" ng-click="addOrderPackage()">
<span class="fa fa-plus"></span> Add Package</a>
</div>
CODE SNIPPETS :
_this.addOrderPackage = function() {
_this.orderproductspackages.push({ ordernumber:_this.order.ordernumber });
}
_this.addOrderContent = function() {
_this.orderproductscontents.push({
ordercontentname:'',
ordercontentquantity:'1',
ordercontentprice:'',
ordercontentpriceper:'',
ordercontenttotal:''
});
}
Of course, all items in your packages are the same, because you use the same content array inside packages: ng-repeat="ordercontent in orderproductscontents". If I understand you right, you need this array orderproductscontents to be distinctive in each package. To do this store this array in package object, like this:
_this.addOrderPackage = function() {
_this.orderproductspackages.push({
ordernumber: _this.order.ordernumber,
contents: []
});
}
and then just ng-repeat="ordercontent in orderpackage. contents"

Input name is not getting interpolated from {{}} to the value

Below is the attached picture of the form constructor. As you can see it has {{service.name}} in it instead o fthe name itself.
I have a form inside that I have two ng-repeats with custom filters on it and inside that I have an input field. I am trying to have a unique name for my input field by adding an index or by using a field from the html response. Regardless of that, when I have name="{{customitem.name}}" or name="{{$index}}" the form generates a constructor with {{customitem}} or {{$index}} instead of the value it self. Also this form turned on and off using ng-if.

<button class="btn-yellow" type="submit" name="submit" ng-click="postProfil()">Simpan Perubahan</button>

Here is the angularjs code
$scope.getProfil = function(){
$http.get('/getUrl').success(function(data){
$scope.profil = data;
})
}
$scope.getProfil();
$scope.profile = {};
$scope.postProfil = function(){
$http.post('/postUrl').success(function(data){
$scope.getProfil();
}).error(function(data){
console.log(data);
})
}
$scope.range = function(min, max, step){
step = step || 1;
var input = [];
for (var i = min; i <= max; i += step) input.push(i);
return input;
};
one thing for sure, I know that http.post using only link is a bad idea, but before I do that, I have debug it using alert javascript function, for example I want to get the data from profile.name so I alert it (profile.name) inside the postProfil function but it returns undefined.
here is the key that should be inputed in the http.post
address
phone
birth
gender
name
I would like to use the http array structure such as
$http.post({
method: 'POST',
url: '/postUrl',
data: {
//data is here
}
})
what do you guys think? Thanks
EDIT:
Maybe I will change my questions, do you know the code for updating data from previous data in an apiUrl using AngularJS? So my problem is that getProfil and postProfil is in the same key and value (but I think some of the keys are different).
Just use the ng-model $scope.profile:
$scope.postProfil = function(){
$http.post('/postUrl', $scope.profile).success(function(data){
$scope.getProfil();
}).error(function(data){
console.log(data);
})
}
$http.post('api/create/something', yourData)
should do the trick for your problem.
$http.post accepts (url, data?, options?)
$http on the other hand accepts (options) directly. You can use it like
$http({
url: 'api/create/something',
data: yourData,
method: 'POST'
}).then(....)
This code works the same with the code above.
Regarding the inaccurate data binding. It might be case sensitivity issues, or serialization issues coming from your rest api configuration. Sometimes PascalCased variable does not bind to camelCased variables as it is. Some configurations are needed to be done.
