在javascript文件中将一个函数的值赋值给另一个函数

Question

我正在研究angularjs google的柱形图。我的要求是将一个javascript函数的值分配给其他javascript函数中定义的另一个变量。对于myController.js

var globalID; 
    app.controller('myChart',['$rootScope','$scope','$uibModal','myService',function($rootScope,$scope,$uibModal,myService) { 
    $scope.chart = {}; 
    $scope.chart.options = { 
     "title": "Summary API Tests", 
     'fontSize': '12', 
     "isStacked": "true", 
     colors: ['blue', 'cyan', 'red'], 
     axisFontSize : 8, 
    }; 
    $scope.chart.type = "ColumnChart"; 
    $scope.function2= function(event) { 
     alert('in function2'); 
     /* want to assign the value of val from below lines to globalID */ 
     /* globalID = val; */ 
    }; 
    /* I want to invoke below lines in $scope.chartClick*/ 
    $scope.function1= function (selectedItem) { 
      $scope.chart.data.rows[selectedItem.row].c[0].v; 
      val = $scope.chart.data.rows[selectedItem.row].c[0].v; 

      alert("inside function1: " + val); 
     }; 

     //some more logic below 


     }); 

在上述js文件

示例代码片段，我想val的从$ scope.function1值分配给内部函数2 globalID。

的范围内设定值

$scope.selected = function (selectedItem) { 
    $scope.chart.data.rows[selectedItem.row].c[0].v; 
    $scope.selectedBarId = $scope.chart.data.rows[selectedItem.row].c[0].v; 
    alert("Selected bar : " + $scope.selectedBarId); 
}; 

$scope.chartClick = function(event) { 
    alert('in chartClick'); 
    if($scope.selectedBarId){ 
     // your business if a bar is selected 
    } 
};
