*这里是复选框的html代码，使用复选框从数据库进行动态值初始化，但复选框没有选择任何值*

<%= f.check_box :admin, {}, 'true', 'false' %>

和js控制器代码

                <div  class="widget-body" style="display: block;">
                        <div class="widget-main">
                                <div class="table-responsive">
                                <table class="table">

                                <thead>
                                <tr>
                                <th>item</th>
                                <th>received</th>
                                    </tr>
                                </thead>

                    <tbody ng-repeat="emp in nodueaccountassets">      
        <tr>
<td>{{emp}}</td>  <td> <input type="checkbox"  ng-model="emp.selected" value="{{emp.name}}"/></td>

                             </tr>
                        </tbody>

Answer 1

假设您想要获得所选员工，您可以这样做，

＆＃13;

 var app = angular.module("app", []);

 app.controller("listController", ["$scope",
   function($scope) {
     $scope.albumNameArray = [];
     $scope.nodueaccountassets = [{
       "name": "Raymond",
       "age": 28,
       "selected": false
     }, {
       "name": "Bruce",
       "age": 96,
       "selected": false
     }, {
       "name": "Laura",
       "age": 62,
       "selected": false
     }];
     $scope.getSelected = function() {
       angular.forEach($scope.nodueaccountassets, function(emp) {
         if (emp.selected) 
         $scope.albumNameArray.push(emp.name);
       })
     }

   }

 ]);

Answer 2

可能是您从服务器获取的以字符串格式选择emp.selected而不是布尔值的值，您获得的值如“true”，

检查你是否得到这样的响应，如果你需要将所选对象转换为布尔值。

[{
 name: 'sushil',
 selected: "true"
}]

我的复选框未在angularjs中选中任何框
