未定义的外部范围ui-grid

Question

我正在尝试使用指令显示ui-grid页脚的外部作用域。外部作用域在表上正确显示，但是当我尝试在链接函数中访问它时，该变量是未定义的。想法？

app.directive('testDir',[function(){
    return {
        restrict: 'E',
        replace: true,    
        transclude: true,
        template: '<div>{{t1.val}}</div>',
        scope: {
          t1: '='
        },link: function(scope){
          console.log(scope); //=====>t1 is there in the console.
          console.log(scope.t1); //=====>t1 is undefined in console.          
        }
    };  
}]);

我认为问题在于您尝试在其父指令分配任何值之前获取该属性。尝试将指令更改为：

app.directive('testDir',['$timeout', function($timeout){
  return {
        restrict: 'E',
        replace: true,    
        transclude: true,
        template: '<div>{{t1.val}}</div>',
        scope: {
          t1: '='
        },link: function(scope){
          $timeout(function() {
              console.log(scope); //=====>t1 is there in the console.
              console.log(scope.t1); //=====>t1 is undefined in console.          
          });
        }
  };  
}]);
