angular：使用变量键访问JSON值

Question

I have a variable param in scope as $scope.param that is always either foo or bar . I'm creating a table with rows defined by <tr ng-repeat="d in data"> .

When I have the following: <td>{{d.foo}}</td> or <td>{{d.bar}}</td> everything works and the data shows up fine. However, when I have <td>{{d.param}}</td> angular can't find anything and the cell is blank.

In other words, I'm trying to access an object value using a variable as the key rather than the key itself. Any idea how to do this?

使用括号表示法：

{{d[param]}}
