javascript - 单选按钮AngularJS的parseInt返回值

Question

这几天我一直在努力解决这个问题......

作为评论表单的一部分，我有一组单选按钮可以对 1 到 5 之间的内容进行评分，每个按钮设置为 value = 1、value = 2 等等。但是当数据返回到 Controller 并推送到 db.json 文件时，单选按钮值是字符串类型。如何让它们成为 int 类型？

单选按钮 HTML 代码:

<label class = "radio-inline" for = "one"><input type = "radio"
name = "rating" id = "one" data-ng-model = "userComment.rating" 
value = 1 required>1</label>

来自 controllers.js 的代码:

$scope.submitComment = function() {
  $scope.movie.comments.push($scope.userComment);
  myFactory.getMovies().update({id:$scope.movie.id}, $scope.movie);

我试过这个，认为它会起作用，但它没有。

$scope.userComment.rating = parseInt($scope.userComment.rating);

只需尝试使用 ng-value而不是 value 属性:

<label class = "radio-inline" for = "one"><input type = "radio"
name = "rating" id = "one" data-ng-model = "userComment.rating" 
ng-value = "1" required>1</label>
