Hello I am using angularjs ui bootstrap and I have one text field in a modal window, which when I try to print it in alert window it is empty. Any reasons why? Here is a plunker of the code.

推荐答案

尝试更改

• $scope.testField

进入

• $scope.myModel.testField (或 user.firstName...)

如本视频中所述angular JS - 最佳实践 (29:19):

As mentioned in this video angular JS - best practice (29:19):

每当你有 ng-model 时，就必须在某个地方有一个点.如果你没有一个点，你就做错了."

"Whenever you have ng-model there's gotta be a dot in there somewhere. If you don't have a dot, you're doing it wrong."
