How To Total Sum Inside Of Array Values In Angularjs?

Question

I am using MEAN stack in my application with AngularJS as my front-end. How to total sum inside of array values in angularjs , actually we have used ng-repeat inside of one more ng-repeat to fetch the value in table and I got the fetched value like 250 in Sprice then I'm expecting to totalsum the sprice value like as a ans= 250.

My Plunker.

• We have used two ng-repeat to get the sprice values in table because sprice is in inside of the [array].

• We need to calculate total sum of sprice of value in table.

• We have filter functionality to calculate the totalsum of ng-module value if it is in without array.

• Actually we dont' know how to use resultValue= in ng-repeat.

• For example: sprice value is 250 in table means the totalsum value need to be in 250, if sprice value is 250 and 300 means expecting answer like 550.

• Without array totalsum functionality: My Plunker

• With array totalsum functionality: My Plunker

My Controller:

  .filter('sumOfValue', function () {
    return function (data, key) {
        debugger;
        if (angular.isUndefined(data) && angular.isUndefined(key))
            return 0;        
        var sum = 0;

        angular.forEach(data,function(v,k){
            sum = sum + parseFloat(v[key]);
        });        
        return sum.toFixed(2);
    }
})

My Data:-

    $scope.orders = [
{
"_id": "5836b64083d9ce0f0078eae8",
"user": {
"_id": "579bdf6123f37f0e00a40deb",
"displayName": "Table 1"
},
"__v": 8,
"total": "1824",
"ordercar": [],
"orderfood": [
{
"qty": "1",
"confirm": "placed",
"sprice": 250,
"price": 250,
"customise": "With Onion,Without Onion",
"name": "Baasha Pizza"
}
],

}]

My Html:-

<table ng-table="tableParams"  class="table table-bordered ">
    <thead>
    <tr>

        <th rowspan="2">s.no</th>
        <th rowspan="2"> sprice </th>
        </tr>
</thead>
        <tr ng-repeat="order in orders">


            <td>{{$index + 1}}</td>
            <td ng-repeat="ram in order.orderfood">{{ram.sprice }}</td>


           </tr>
           <tr>
             <td>sum</td>

             <td>{{resultValue | sumOfValue:'sprice'}}</td>


           </tr>
          </table>

*We expecting for total sum in array values.

Used ng-repeat:

<tr ng-repeat="order in orders">


            <td>{{$index + 1}}</td>
            <td ng-repeat="ram in order.orderfood">{{ram.sprice }}</td>

Answer 1

Here you can call function using "ng-init", so that angularjs will call function before execution of "ng-repeat".

In that function you can perform iteration and calculate total and hold it in scope variable to display it.

Answer 2

ng-repeat is not looping properly .. I fixed it .. Check below snippet and also i added one more array to it.......... let me know..

var app = angular.module('plunker', []);


app.filter('sumOfValue', function () {
    return function (data, key) {
        debugger;
        if (angular.isUndefined(data) && angular.isUndefined(key))
            return 0;        
        var sum = 0;
        
        angular.forEach(data,function(v,k){
            sum = sum + parseFloat(v[key]);
        });        
        return sum.toFixed(2);
    }
}).controller('MainCtrl', function($scope) {
  $scope.orders = [
{
"_id": "5836b64083d9ce0f0078eae8",
"user": {
"_id": "579bdf6123f37f0e00a40deb",
"displayName": "Table 1"
},
"__v": 8,
"total": "1824",
"ordercar": [],
"orderfood": [
{
"qty": "1",
"confirm": "placed",
"sprice": 250,
"price": 250,
"customise": "With Onion,Without Onion",
"name": "Baasha Pizza"
},
{
"qty": "2",
"confirm": "placed",
"sprice": 250,
"price": 250,
"customise": "With Onion,Without Onion",
"name": "Baasha Pizza"
}
],
"phone": null,
"order_source": "",
"comment": "",
"payment_mode": "",
"nop": null,
"rating": null,
"bill": false,
"complete": false,
"laundry": false,
"clean": false,
"roomservice": false,
"napkin": false,
"waiter": false,
"water": false,
"name": "fgg",
"created": "2016-11-24T09:43:28.413Z",

}]
