[removed] loop through object properties [duplicate]

Answer 1

I think you are looking for the in operator, combined with the for loop. Check this MDN

or try like this:-

for (var property in object) {
    if (object.hasOwnProperty(property)) {
        // do stuff
    }
}

In your case:-

for (var fieldName in scope.filters) {
if (scope.filters.hasOwnProperty(fieldName))
{
 //.....
}
