Angularjs 在Angular.js中显示json数据

我正在使用下面的代码，我只获得问题id，但我需要的是当我单击

保存

按钮时，我想在文本框下方显示

问题.id

，

选项.id

和

所选

：

真

或

假

。下面的代码是正确的，但要使其与数组类似

controllers.js

 $scope.save = function() {
        $scope.msg = 'Question IDs:';
        $scope.questions.forEach(function(el){
            console.log(el)
            $scope.msg += el.Id + ',';
        })
 }

{
    "quiz": {
        "Id": 2,
        "name": "C# and .Net Framework",
        "description": "C# and .Net Quiz (contains C#, .Net Framework, Linq, etc.)",
        "paragraph": "In 2015 Microsoft released ASP.NET 5.ASP.NET 5 is a significant redesign of ASP.NET.ASP.NET, MVC, and Web Pages are now merged into a single framework named MVC 6.It includes the following features:Linux support OSX support Node.js supportA ngularJS supportTag ,HelpersView, ComponentsWeb ,APIGruntJS ,supportBower, supportNo ,Visual BasicNo Web Forms"
    },
    "config": {
        "shuffleQuestions": true,
        "showPager": false,
        "allowBack": true,
        "autoMove": false
    },
    "questions": [{
        "Id": 1010,
        "Name": "Which of the following assemblies can be stored in Global Assembly Cache?",
        "QuestionTypeId": 1,
        "Options": [{
            "Id": 1055,
            "QuestionId": 1010,
            "Name": "Private Assemblies"
        }, {
            "Id": 1056,
            "QuestionId": 1010,
            "Name": "Friend Assemblies"
        }, {
            "Id": 1057,
            "QuestionId": 1010,
            "Name": "Public Assemblies"
        }, {
            "Id": 1058,
            "QuestionId": 1010,
            "Name": "Shared Assemblies"
        }]
    }, {
        "Id": 1019,
        "Name": "Which of the following does NOT represent Integer?",
        "QuestionTypeId": 1,
        "Options": [{
            "Id": 1055,
            "QuestionId": 1010,
            "Name": "Char"
        }, {
            "Id": 1056,
            "QuestionId": 1010,
            "Name": "Byte"
        }, {
            "Id": 1057,
            "QuestionId": 1010,
            "Name": "Short"
        }, {
            "Id": 1058,
            "QuestionId": 1010,
            "Name": "Long"
        }]

    }]
}

在

$scope.questions

中存储所有json数据

home.html

<div ng-repeat="question in filteredQuestions">
            <div class="label label-warning">Question {{currentPage}} of {{totalItems}}.</div>
            <div class="row">
                <div class="row">
                    <h3>{{currentPage}}. <span ng-bind-html="question.Name"></span></h3>
                </div>
            </div>
            <div class="row text-left options">
                <div class="col-md-6" ng-repeat="option in question.Options" style="float:right;">
                    <div class="option">
                        <label class="" for="{{option.Id}}">
                           <h4> <input id="{{option.Id}}" type="checkbox" ng-model="option.Selected" ng-change="onSelect(question, option);" />
                            {{option.Name}}</h4>
                        </label>
                    </div>
                </div>
                </div>

            <div class="center"><button ng-click="save()">Save</button></div>
            <div class="center"><textarea  rows="5" cols="50">{{msg}}</textarea></div>
        </div>

可以将整个对象传递给函数，如下所示：

<div ng-repeat="question in filteredQuestions">
        <div class="label label-warning">Question {{currentPage}} of {{totalItems}}.</div>
        <div class="row">
            <div class="row">
                <h3>{{currentPage}}. <span ng-bind-html="question.Name"></span></h3>
            </div>
        </div>
        <div class="row text-left options">
            <div class="col-md-6" ng-repeat="option in question.Options" style="float:right;">
                <div class="option">
                    <label class="" for="{{option.Id}}">
                       <h4> <input id="{{option.Id}}" type="checkbox" ng-model="option.Selected" ng-change="onSelect(question, option);" />
                        {{option.Name}}</h4>
                    </label>
                </div>
            </div>
            </div>

        <div class="center"><button ng-click="save(question, option)">Save</button></div>
        <div class="center"><textarea  rows="5" cols="50">{{msg}}</textarea></div>
    </div>

在控制器中使用此代码可将问题id设置为选定选项id和非选定选项id

$scope.save = function() {
  console.log('Question IDs:' + question.id);
  $scope.questions.Options.forEach(function(option){
        if(option.selected){
           console.log('Selected Options:' +option.id)
           $scope.msg = 'Question IDs: ' + question.id + ', Selected option id: ' + option.id;
        }
        else{
           console.log('Not selected Options:' +option.id)
        }
  })
}

希望有帮助

但这里我需要显示问题Id和所选选项Id。如果选择了任何答案，则包括所选：true否则所选：false@Sjoerddewitget在参数后出现类似Uncaught SyntaxError:missing）的错误list@Sherin我很抱歉。忘记将操作员添加到控制台中的concat

+

。请再试一次。是的，我发现了，我们需要在使用console.log（question.id）之前调用question。但是问题Id已经在选项中。所以我以前调用option.QuestionId，但它会给我类似“无法读取每个属性”的错误。这里的错误是什么@mJunaidSalaat

$scope.save = function() {
  console.log('Question IDs:' + question.id);
  $scope.questions.Options.forEach(function(option){
        if(option.selected){
           console.log('Selected Options:' +option.id)
           $scope.msg = 'Question IDs: ' + question.id + ', Selected option id: ' + option.id;
        }
        else{
           console.log('Not selected Options:' +option.id)
        }
  })
}
