How to iterate through angular $scope variables with a loop

问题

I want to iterate through $scope variables with a for loop like this. In this example the $scope object includes an object accounts inlcuding 5 objects, whose names are numbers from 1 to 5. Each of them has a name.

for(var i = 1; i < 5; i++){
   $('#name').val($scope.accounts.i.name);
}

The problem: $scope.accounts.i is undefined because i does not count as a varibale inside the $scope variable. It counts as the letter i, so I see no chance to iterate through a scope with a for loop. When I use " " around the $scope variable it will just be displayed as plain html and angular is not interpreted.

回答1:

Angular way to do above is

 $scope.accounts=[{name:"123"},{name:"124"},{name:"125"}]

            angular.forEach($scope.accounts,function(value,index){
                alert(value.name);
            })

回答2:

If accounts is an array, you can use the array indexer:

for(var i = 1; i < 5; i++){
   $('#name').val($scope.accounts[i].name);
}
