angularjs looping logic, forEach

Question

I have an object that looks like this. Basically what I need is to loop through the filterNameList array and pull out the first value in each of the objects that belong to the filterNameList, it will always be the [0] value. Having some trouble getting these extracted out to display on the page.

acceptableFlag: "True"
filterNameList: Array[5]
    0: Array[2]
        0: "Asia"
        1: 20000
    1: Array[2]
        0: "China"
        1: 20001
    2: Array[2]
        0: "Beijing"
        1: 50000
reportId: 48
reportName: "Multiple"

Would the following function work?

function filterLabel(data){
    angular.forEach(data, function(obj, i){
        angular.forEach(obj, function(filterNameList, i){
            if (filterNameList.filterNameList == 20000){
                filterNameList.filterLabel = "Region"
            }
        })
    })
 };

Why do you use angular.forEach as opposed to data.filterNameList.forEach(function(nameList, i) {}) — Daniel Kobe

throughout other places in the code i've seen angular.forEach being used, so I adopted it also — Buccaneer

obj is an array as well. You'll either have to nest a loop, or do a static index value.

if(obj[1] == 20000){
    obj.regionName = "Region"
}

Assigning property to an Array object is not a good way of doing this. You can do something like

filterNameList.forEach(function(obj, i){
   if(obj[1] == 20000){
        obj.push("Region")
    }
   else if (obj[1] == 20001){
       obj.push('Country');
   }
   else if (obj[1] == 50000){
       obj.push('City');
   }

});

so would it be like this: function filterLabel(data.filterNameList){ filterNameList.forEach(function(obj, i){ if.... } }

Right.. after this your sub arrays will contain 3 items each

I am getting an error, saying "Not a function / got undefined"

Maybe there is a typo or filterNamesList is undefined
