Searching through multiple ng-repeats at once

问题

i'm currently working on an application that is build with AngularJS as a base, and that obtains data through the prestashop webservice. All data obtained are JSON strings sorted through multiple files. Now i'm trying to create a searchbox that filters through some objects the moment the user fills in the searchbox. The easy way is ofcourse by using the ng-model and filter: combination like below:

angular.module('myApp', []).controller('namesCtrl', function($scope) {
    $scope.names = [
        'Jani',
        'Carl',
        'Margareth',
        'Hege',
        'Joe',
        'Gustav',
        'Birgit',
        'Mary',
        'Kai'
    ];
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<!DOCTYPE html>
<html>
<body>

<div ng-app="myApp" ng-controller="namesCtrl">

<p>Type a letter in the input field:</p>

<p><input type="text" ng-model="test"></p>

<ul>
  <li ng-repeat="x in names | filter:test">
    {{ x }}
  </li>
</ul>

</div>


<p>The list will only consists of names matching the filter.</p>


</body>
</html>

But what if you're using two different sources? and two different ng-repeats? So in my application some of the data is about customers. The data is obtained through two different $http.get() functions. One is for the customers basic information. The second one is the address information. Take a look below:

// Get the customers
$http.get('config/get/getCustomers.php', {cache: true}).then(function(response){
    $scope.customers = response.data.customers.customer
});

// Get the addresses
$http.get('config/get/getAddress.php', {cache: true}).then(function (response) {
    $scope.addresses = response.data.addresses.address
});

By using ng-repeat and ng-if i'm able to filter the information and connect it together. ng-if="customer.id == address.id_customer" ng-repeat=...

A full example below:

angular.module('myApp', []).controller('namesCtrl', function($scope) {
    $scope.customers = [{
        'id': 1,
        'name': 'Jani'
        },{
        'id': 2,
        'name': 'Carl'
        },
        {
        'id': 3,
        'name': 'Tim'
        },
        {
        'id': 4,
        'name': 'Tom'
        }
    ];
    
    $scope.addresses = [{
        'id': 1,
        'id_customer': 1,
        'place': 'Street 12'
        },{
        'id': 2,
        'id_customer': 2,
        'place': 'Other street'
        },
        {
        'id': 3,
        'id_customer': 3,
        'place': 'marioworld!'
        },
        {
        'id': 4,
        'id_customer': 4,
        'place': 'Space!'
        }
    ];
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
  <div ng-controller="namesCtrl">
    <div ng-repeat="customer in customers">
        <div ng-bind="customer.id + ' - ' + customer.name"></div>
        <div ng-if="customer.id == address.id_customer" ng-repeat="address in addresses" ng-bind="address.place">
    </div>
  </div>
</div>

So as you can see i'm able to create the combination with the ng-if but now i would like to create a search input that's able to search through both fields. And that's where my issue starts. I'm able to create it for one ng-repeat. But what if i want to Search on the address and the customer? I would like to create the possibility of letting the user search by customer name, street address and ZIP code. But the ZIP code and address are from a different source.

I hope that someone has found a solution for this and if you have any questions please ask them in the comments.

As always, thanks in advance!

I'd suggest to map your customers array adding to each object it's own place this way:

$scope.customers.map( function addPlace(item) {
   item.place = $scope.addresses.reduce(function(a,b){
       return item.id === b.id_customer ? b.place : a;
   }, '');
   return item;
})

This way your template will be easier to read, and you will be able to use your previous search.

angular.module('myApp', []).controller('namesCtrl', function($scope) {
    $scope.customers = [{
        'id': 1,
        'name': 'Jani'
        },{
        'id': 2,
        'name': 'Carl'
        },
        {
        'id': 3,
        'name': 'Tim'
        },
        {
        'id': 4,
        'name': 'Tom'
        }
    ];
    
    $scope.addresses = [{
        'id': 1,
        'id_customer': 1,
        'place': 'Street 12'
        },{
        'id': 2,
        'id_customer': 2,
        'place': 'Other street'
        },
        {
        'id': 3,
        'id_customer': 3,
        'place': 'marioworld!'
        },
        {
        'id': 4,
        'id_customer': 4,
        'place': 'Space!'
        }
    ];

    $scope.customers.map( function addPlace(item) {
       item.place = $scope.addresses.reduce(function(a,b){
           return item.id === b.id_customer ? b.place : a;
       }, '');
       return item;
    })

});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
  <div ng-controller="namesCtrl">

  <p><input type="text" ng-model="test"></p>
  <div ng-repeat="customer in customers | filter:test">
        {{ customer.id }} - {{ customer.name }}
        <br>
        {{ customer.place}}
    </div>
  </div>
</div>
