Question

我想在变量中设置选中的radiobutton的值。但我无法得到它。下面是我尝试过的代码

master.controller('FiberLead_Filter', function($scope, $http, NEIQC_Service, Scopes, $rootScope) {
      var rdSelectMP = $scope.MPSelect; // here I am getting undefined
    }

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.25/angular.min.js"></script>
<div class="rightFilter" ng-controller="FiberLead_Filter as Filter" id="FiberLead_Filter">
  <div class="pdfDownload customeRadioWrap">
    <div class="customeRadio">
      <input type="radio" id="btnCurrentMP" name="radio-group" ng-model="MPSelect" ng-value="Current">
      <label for="btnCurrentMP">Current MP</label>
    </div>
    <div class="customeRadio">
      <input type="radio" id="btnAllMP" name="radio-group" ng-model="MPSelect" ng-value="All">
      <label for="btnAllMP">All MP</label>
    </div>
    <button class="btn btn-default customBtn" ng-click="DownloadExcelReport()"><i class="fa fa-file-pdf-o" aria-hidden="true"></i> Download</button>
  </div>
</div>

让我知道我的代码出了什么问题UNDEFINED

这是因为data = [(1,2,3), (1,5,3), (1,8,3), (1,10,3), (1,16,3), (1,17,3)] MAXIMUM_ANGLE = 5 def angles_within_range(x, y): return abs(x[1] - y[1]) <= MAXIMUM_ANGLE def first_angle_break_index(): for i in range(len(data) - 1): if not angles_within_range(data[i], data[i+1]): return i+1 def valid_angles_list(): return data[:first_angle_break_index()] print(valid_angles_list())正在寻找“全部” ng-value变量，但可能没有任何变量。如果期望值是字符串，请使用$scope，或者使用'All'。

在下面的工作小提琴中，单击“下载”按钮以记录当前值（首先选择一个值）。

value

angular.module('app', []);

angular.module('app').controller('FiberLead_Filter', function($scope, $http, $rootScope) {
      $scope.DownloadExcelReport = function(){
        console.log($scope.MPSelect);
      }
    }
);

无法使用angularJS获取单选按钮的值
