如何在Angularjs中获取复选框值？

Question

我有手机品牌的模特。在这里，当我提交时，我只获得模型名称。而不是那样，我需要选择品牌名称和型号名称以及输入的价格。我已经制作了这样的架构。

  	// If we deselect the brand
  	if ($scope.selectedBrands.indexOf(selectedPhone.brandname) === -1) {
    	// Deselect all phones of that brand
    	angular.forEach($scope.phones, function(phone) {
      	if (phone.brandname === selectedPhone.brandname) {
        	phone.selected = false;
        }
      });
    }
  }
  
  $scope.checkSelectedPhones = function() {
  	var modelNames = [];
  	angular.forEach($scope.phones, function(phone) {
    	if (phone.selected) {
      	modelNames.push(phone.modelname);
      }
    });

我需要输出这样的输出数据。

Answer 1

Working Demo

<div ng-repeat="brand in selectedBrands track by $index" ng-if="brand">
    {{brand}}
    <div ng-repeat="phone in phones" ng-if="phone.brandname === brand">
      <label>
        <input type="checkbox" ng-model="phone.selected">  
        {{phone.modelname}}
        <input type="text" ng-model="phone.price"> <!-- Added new property to the model phone -->
      </label>
    </div>
  </div>

并将checkSelectedPhone函数更新为

$scope.checkSelectedPhones = function() {
    var modelNames = [];
    var aletrMsg= '';
    angular.forEach($scope.phones, function(phone) {
        if (phone.selected) {
        modelNames.push(phone);
        aletrMsg += 'Brand : '+ phone.brandname + 'Phone Name: '+ phone.modelname + ' : Price: '+ phone.price +', ';
      }
    });
    alert(modelNames.length ? aletrMsg : 'No phones selected!');
  }
