php, Laravel 7 - Unable to receive data from AJAX request

I'm still a newbie and currently learning how to use Laravel 7.
My problem is, I tried to pass my data from the controller by using an AJAX request on
my child page. I noticed that when I tried to pass the data from my child page, the page won't
receive it but somehow it's working on a master page (where I didn't use any Blade directives).
I tried to dd() the data in the controller and it does show that there is data.
But it won't pass it to the child page. All the JS files and custom script that I push does
come out on the child page.

Thank you for your time, sir.

Solved it after MORE googling done.
Make sure to add defer inside your DataTable CDN.
Example:
<script src = "http://cdn.datatables.net/1.10.18/js/jquery.dataTables.min.js" defer ></script>
Here's the link where I found the answer:
https://datatables.net/forums/discussion/50869/typeerror-datatable-is-not-a-function-datatable-laravel
For more understanding on why defer is added:

use Yajra\DataTables\Contracts\DataTable;
use Yajra\DataTables\Facades\DataTables;
please use this two line in your controller

Datatable for pagination and searching for live data?

I tried using datatables for live data but my problem is, every time my data updates, I can't use searching and every time I use pagination, it goes back to first page. Can somebody knows what datatable plugin is compatible with angular?
Here is my code for realtime update of data:
angular.module('selectExample', [])
.controller('ExampleController', ['$scope','$interval', function($scope,$interval) {
$interval(function () {
$scope.register = {
regData: {
branch: {},
},
names: [
{name:"narquois"},{name:"vorpal"},{name:"keen"},
{name:"argol"},{name:"long"},{name:"propolis"},
{name:"bees"},{name:"film"},{name:"dipsetic"},
{name:"thirsty"},{name:"opacity"},{name:"simplex"},
{name:"jurel"},{name:"coastal "},{name:"fish"},
{name:"kraken"},{name:"woman"},{name:"limp"},
],
};
}, 1000);
}]);
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<div ng-app="selectExample" ng-controller="ExampleController">
<table id="example" width="100%">
<thead>
<tr align="center">
<th>Name</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="person in register.names">
<td align="center">{{ person.name }}</td>
</tr>
</tbody>
</table>
</div>

Enable state saving and override state save/load handlers to use only the table's DOM id:
$('#example').dataTable( {
stateSave: true,
stateSaveCallback: function(settings,data) {
localStorage.setItem( 'DataTables_' + settings.sInstance, JSON.stringify(data) )
},
stateLoadCallback: function(settings) {
return JSON.parse( localStorage.getItem( 'DataTables_' + settings.sInstance ) )
}
} );

You have to initialize your DataTable with the option stateSave. It enables you to keep the pagination, filter values, and sorting of your table on page refresh. It uses HTML5's APIs localStorage and sessionStorage.
$('#example').dataTable( {
stateSave: true
});

how to pass json data into query string and use that data in another page

Here table contains book details which contains book name, author, pric, ISBN and category. When user click on Book Name it should pass the data to another page using querystring
<script type="text/javascript" src="book.js">
<body ng-app="mymodule" >
<div ng-controller="myController" >
<table border=2>
<thead>
<tr>
<th>ISBN</th>
<th>NAME</th>
<th>AUTHOR</th>
<th>CATEGORY</th>
<th>PRICE</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="book in books">
<td>{{ book.ISBN }}</td>
<td >{{ book.Name }}</td>
<td>{{ book.Author }}</td>
<td>{{ book.Category }}</td>
<td>{{ book.price }}</td>
</tr>
</tbody>
</table>
books.js
var myapp = angular.module('mymodule', []);
myapp.controller("myController", function($scope, $http,$window) {
$http.get("https://api.myjson.com/bins/p4ujn").then(function(response) {
$scope.books = response.data;
$scope.getdetail=function(){
$scope.getbookdetail=this.book;
$window.location.href = "orderpage.html";
}
});
});
orderpage.html
<script type="text/javascript" src="book.js"></script>
<body ng-app="mymodule" >
<div ng-controller="myController" >
{{getbookdetail.Name}}<br>
{{getbookdetail.Author}}
{{getbookdetail.price }}<br>
</div>
</body

So you said this: 'When user click on Book Name it should pass the data to another page using querystring'
Querystring is not the best method to use for something like this. You're better off learning about ui-router and setting up routes that handle this. You have your initial state, then you can create another state to display each book. Something like this:
.state('initial', {
url: 'some/initial',
template: 'some/initial/template.html',
params: {
name: null,
price: null,
author: null,
isbn: null,
category: null
}
})
.state('read-book-details', {
parent: 'initial',
url: 'some/url',
template: 'some/template.html',
params: {
name: null,
price: null,
author: null,
isbn: null,
category: null
}
})
Then when you're transitioning from one 'state' to another, you do it like so passing along the parameters you want:
$state.go('read-book-details',
{ name: book.name, price: book.price, author: book.author });
On the 'other' page's controller (ie the controller for the 'read-book-details' state) you can inject $state and get the parameters that are passed in via $state.params (ie., $state.params.price)
A second option for you is to have a service that you can store the data in, then retrieve from anywhere else. This obviously becomes useful when you start to pass around larger amounts of data rather than simpler smaller pieces (like name, price).

Flexible table ng-repeat

Is the following possible and if so how do I change my HTML to allow it?
I have the following model;
prospect = [{"name":"jamie",
"phones": [{
"type":"home",
"number":"01275"},
{
"type":"mobile",
"number":"0788"}]},
{"name":"peter",
"phones": [{
"type":"mobile",
"number":"07852"}]}
]
and I would like to display - in an angularjs table - like this
name home mobile
jamie 01275 0788
peter 07852
My current HTML
<table>
<tbody ng-repeat='person in prospect'>
<th>Name</th>
<th ng-repeat="phone in person.phones">{{phone.type}}</th>
<tr>
<td>
{{person.name}}
</td>
<td ng-repeat='phone in person.phones'>
{{phone.number}}
</td>
</tr>
</tbody>
</table>
produces
Name home mobile
jamie 01275 0788
Name mobile
peter 07852
http://jsfiddle.net/jaydubyasee/D7f2k/

To do this in html, without modifying your json, I'd first add an array that indicates what type of phone goes into each column:
$scope.types= ["home","mobile"];
Then use it in the header:
<th ng-repeat="type in types">{{type}}</th>
Then to print out the phone numbers we iterate over each phone within each column, using ngIf to conditionally show any phones that match that column's type:
<td ng-repeat='type in types'>
<span ng-repeat='pphone in person.phones' ng-if="pphone.type == type">
{{pphone.number}}
</span>
</td>
updated fiddle
A variation would be to replace the nested ngRepeats with a custom directive that displays the correct phone for the given column and row.

I hope you will like this solution :)
I did you this dependency
bower install angular
bower install ng-tasty
bower install bootstrap
And here the full solution
<div tasty-table bind-resource="resource">
<table class="table table-striped table-condensed">
<thead tasty-thead></thead>
<tbody>
<tr ng-repeat="row in rows">
<td ng-bind="row.name"></td>
<td ng-bind="row.phones | filterTypeColumn:'home'"></td>
<td ng-bind="row.phones | filterTypeColumn:'mobile'"></td>
</tr>
</tbody>
</table>
</div>
<script src="bower_components/angular/angular.min.js"></script>
<script src="bower_components/ng-tasty/ng-tasty-tpls.min.js"></script>
<script>
angular.module('stackOverflowAnswer', ['ngTasty'])
.filter('filterTypeColumn', function() {
return function (input, typeColumn) {
var phoneNumber;
input.forEach(function (phone) {
if (phone.type === typeColumn) {
phoneNumber = phone.number;
}
})
return phoneNumber;
};
})
.controller('StackOverflowController', function ($scope) {
$scope.resource = {
"header": [
{ "name": "Name" },
{ "home": "Home" },
{ "mobile": "Mobile" }
],
"rows": [
{
"name":"jamie",
"phones": [
{ "type":"home","number":"01275" },
{ "type":"mobile", "number":"0788"}
]
},
{
"name":"peter",
"phones": [
{ "type":"mobile","number":"07852"}
]
}
]
};
});
</script>
</body>
</html>
If you want know more about ngTasty you can find all the doc here http://zizzamia.com/ng-tasty/directive/table .
For your specific case, the solution was make a custom filter.

How to use EMBER.SORTABLEMIXIN?

My FIXTURES contains array of products which i want to sort based on ID.
Astcart.Application.FIXTURES=[
{
"name" : "astr",
"home_products": [
{
"id": 3,
"name": "Mobiles & Accessories"
},
{
"id": 2,
"name": "Mobiles & Accessories"
},
{
"id": 1,
"name": "Mobiles & Accessories"
}
]
}
];
I am not getting complete example of EMBER.SORTABLEMIXIN.I don't have any idea about sorting in ember.
Can anyone explain me how to do sorting in ember using my this example(Not working)?

The sortable feature is provided by Ember.SortableMixin. This mixin expose two properties: sortAscending and sortProperties.
The sortAscending accepts a boolean value determining if the sort is ascendant or not.
And the sortProperties expect an array with the properties to sort.
For instance:
Controller
App.IndexController = Ember.Controller.extend(Ember.SortableMixin, {
sortAscending: false,
sortProperties: ['id'],
});
These properties can be changed and the order will be updated, here is a sample with dynamic sort:
Controller
App.IndexController = Ember.Controller.extend(Ember.SortableMixin, {
sortProperties: ['firstName'], // or whatever property you want to initially sort the data by
sortAscending: false, // defaults to "true"
actions: {
sortBy: function(property) {
this.set('sortProperties', [property]);
}
}
});
To access the arranged content, you should refer to arrangedContent in your template instead of the regular model property. Like this:
Template
<script type="text/x-handlebars" data-template-name="index">
<h2>Index Content:</h2>
<table>
<thead>
<th {{action "sortBy" "id"}}>ID</th>
<th {{action "sortBy" "firstName"}}>First Name</th>
<th {{action "sortBy" "lastName"}}>Last Name</th>
</thead>
<tbody>
{{#each arrangedContent as |prop|}}
<tr>
<td>{{prop.id}}</td>
<td>{{prop.firstName}}</td>
<td>{{prop.lastName}}</td>
</tr>
{{/each}}
</tbody>
</table>
</script>
You can see this working here http://emberjs.jsbin.com/gunagoceyu/1/edit?html,js,output
I hope it helps

Since Ember.SortableMixin is going to be deprecated in Ember 2.0 (as well as the ArrayController), the recommended way to sort will be using Ember.computed.sort(), as illustrated here: https://stackoverflow.com/a/31614050/525338
