比较两个JSON文件时出现未定义的问题

Question

test.json

{"discountPriceValues":[[{"Price":"0.0"},{"Scode":"S0375102"}],[{"Price":"2.0"},{"Scode":"s0779548"}]],"isEmployeeOJ":"Y"}

app.js

var test = $http.get("data/test.json").then(function (response5) {
  $scope.testing = response5.data;
  return response5;
});
test.then(function(testing){
    $scope.testing = testing.data.discountPriceValues;
}); 

for(var x = 0; x < $scope.callplanList.length; x++){
  for(var t = 0; t < $scope.testing.length; t++ ){
                        console.log($scope.testing[t].Scode);
                            if($scope.callplanList[x].s_code == $scope.testing[t].Scode){
                                console.log($scope.testing[t]);
                            }
                    }
}

HTML

<div class="description">
<p>Test</p>
</div>

I need to check the scodes of callplans.json and test.json, if any common values are available then I need to enable a div in HTML. But I'm getting undefined in the console for this code - console.log($scope.testing[t].Scode); and getting the correct values as 2 for $scope.testing.length;

Any help would be appreciated

Note: I'm not attaching the other JSON files and code because for this functionality those are not required.

Answer 1

Since the format of your data is weird, that would have to be:

console.log($scope.testing[t][1].Scode);

See also the snippet below.

 const data = { "discountPriceValues": [ [{ "Price": "0.0" }, { "Scode": "S0375102" }], [{ "Price": "2.0" }, { "Scode": "s0779548" }] ], "isEmployeeOJ": "Y" }; for (var t = 0; t < data.discountPriceValues.length; t++) { console.log(data.discountPriceValues[t][1].Scode); } 

Answer 2

I saw that your json object contains nested arrays.

As I said in comments, just change to $scope.testing[t][1].Scode , because you have nested arrays.

I suggest to use filter method in order to check if you have common values.

let callplanListCodes = $scope.callplanList.map(a=>a[1].Scode);
let testingCodes = $scope.testing.map(a=>a[1].s_code;
$scope.hasCommon = callplanListCodes .filter((n) => testingCodes .includes(n))

HTML

<div ng-if="hasCommon" class="description">
  <p>Test</p>
</div>
