Yes and no. If you want to display any of the data then one binds the JSON data to HTML with ng-repeat. If it only a summary which is required the any form of loop (either via Angular or just plain old javascript) will do. Could be you a bit more specific?

Thanks for the comments.
I am not display the data in html directly. I need modified my controller js file . In the controller js file, there are two rest web service call, I got two set of json data from web service, I need loop these two list (json data)  in the scope to find a match of the type code, so I can add a new indicator in one of the json data , then I can send the json data back to html.

Hi,
Here is my code:
sc.getTypes = function() {
                        
                                    return $http({
                                          headers: {"content-type": "application/json"},
                                         method: "GET",
                                         url: get_types_uri,
                                       })
                                     .then(function(response) {
                                           if(response.data.success) {
                                                 //get responses
                                                 sc.myList = response.data.data;
                                                 angular.foreach(sc.myList, function(value1,key){
                                                       console.log("value1: "+ value1);
                                                       angular.foreach(sc.userDetail, function(value2, key){
                  
                                                             
                                                             console.log("value2: "+ value2);
                                                             
                                                       },this)
                                                       
                                                 },this)
                                                       
                                                 } else {
                                                       sc.errors = ErrorHandlingSvc.processRESTErrorResponse(response.data.error);
                                                 }
                                                       
                                                 }, function(response) {
                                                       sc.errors = ErrorHandlingSvc.processSystemError(response.data);
                                                 });
                                               
                                }

Notes: I already get sc.userDetail from another web service call.
I got an error of this line: angular.foreach(sc.myList, function(value1,key){
the error is : Error: angular.foreach is not a function

Thanks

HI, BigRat:
Here are the two jason data set:
 sc.myList= [{
            "typeCode": "A01",
            "typeCodeDesc": "Enrollment"
            },
            {
            "typeCode": "A02",
            "typeCodeDesc": "Legal"
            },
            {
            "typeCode ":"A03",
             "typeCodeDesc ":"Other",

            },
            {
            "typeCode ":"A04",
             "typeCodeDesc ":"Rules",

            }];
      



sc.userDetail=  [{
            "id": "124300",
            "docList": [{
                  "dFormat": "text",
                  "typeCode": "Default"
            }, {
                  "dFormat": "text",
                  "typeCode": "A01"
            }, {
                  "dFormat": "usMail",
                  "typeCode": "A02"
            }, {
                  "dFormat": "email",
                  "typeCode": "A03"
            }, {
                  "dFormat": "email",
                  "typeCode": "A04"
            }],
            "phoneNumber": "1234567891",
            "statusInfo": {
                  "serviceMessage": "SUCCESS",
                  "serviceStatus": "SUCCESS"
            }
      }]

I need loop this two set data based on the typeCode, if the typeCode match each other, then I need add one indicator in sc.myList for the dFormat. Is it doable?  

Thank you very much!

the error is : Error: angular.foreach is not a function

No, it's not. The correct function is forEach()

function createList(typeList,userDocList) {
   var newList = [];
   angular.forEach(typeList,function(obj,index) {
      angular.forEach(userDocList,function(userDoc,index2) {
         if(obj.typeCode===userDoc.typeCode) {
            obj['dFormat']=userDoc.dFormat;
            newList.push(obj);
         };
      });
   });
   return newList;
}

var result = createList(sc.myList,userDetails[0].docLis)t;

Open in new window


I personally prefer not to change any input data but always create something new. It's then easier to compare.
