如何在angularjs中从外部访问函数内部的变量

我在控制器内部有两个函数，但我无法在函数外部打印变量。我们如何解决问题？

I have two functions inside the controller ,But i couldn't print variables outside the function .How can we fix the problem?

var getlockerbalance=function(){

           $http.get("php/selectLOCKERBALANCE.php")
           .success(function(lockerbalance){
           $scope.lockerbalance1=lockerbalance;
            var   lastlockerbalance=$scope.lockerbalance1[0].LOCKERBALANCE;
          console.log(lastlockerbalance);

            })

         }

我的尝试：

What I have tried:

<pre lang="Javascript">
var getlockerbalance=function(){
					
		       $http.get("php/selectLOCKERBALANCE.php")
		       .success(function(lockerbalance){
		       $scope.lockerbalance1=lockerbalance;
				var   lastlockerbalance=$scope.lockerbalance1[0].LOCKERBALANCE;
		      console.log(lastlockerbalance);
				
                })

console.log(lastlockerbalance);

错误表示未定义的lastlockerbalance

The error says that lastlockerbalance in undefined
