Calculating sum of repeated elements in AngularJS ng-repeat

Question

Gautam Parmar · Answer

Hi There are two option to calculate sum
one is looping your array in javascript and calculate another is creating own filter
To loop data
$scop e.getTotal =  function (){
var  total = 0;
for ( var  i = 0; i
var  product = $scope.cart.products[i];
total += (product.price * product.quantity);
}
return  total;
}
Creating Filter
You can find fiddle link https://jsfiddle.net/51ok4mpb/
angular.module( "sampleApp" , []).filter( 'totalSumPriceQty' ,  function () {
return   function (data, key1, key2) {
if  (angular.isUndefined(data) || angular.isUndefined(key1) || angular.isUndefined(key2))
return  0;
var  sum = 0;
angular.forEach(data,  function (v, k) {
sum = sum + (parseInt(v[key1]);
});
return  sum;
}
})
