$ scope.myFunc()不是函数 [英] $scope.myFunc() is not a function

问题描述

我正在尝试将$ scope.span00，span01，span10等绑定到网格中.

I'm trying to ng-bind $scope.span00, span01, span10, and so on in a grid.

$scope.span01 = 'test'; // this works fine

现在可以进行ng-点击...

Now for the ng-click...

$scope.clickedOn = function(row, column) {

  var gridLocation = function() { return 'span'.concat(row).concat(column); } // returns span01
  $scope.gridLocation() = 'test'; // says $scope.gridLocation() is not a function.
}

这不是函数.我在这里做什么?

It's saying it's not a function. What do I do here?

推荐答案

因为该函数在 $ scope 上不存在.这是您需要做的:

Because the function does not exist on $scope. This is what you need to do:

$scope.gridLocation = function (row, column) {
    return 'span'.concat(row).concat(column);
};

$scope.clickedOn = function (row, column) {
    $scope.gridLocation(row, column);
};

修改

按照评论中的要求进行操作(希望我理解正确):

To do what you asked for in the comments (I hope I understood correctly):

$scope.clickedOn = function (row, column) {
    $scope[$scope.gridLocation(row, column)] = 'test';
};
