javascript - Angular 仅从数组中获取所需的数据

Question

我有一个 ng-repeat，它获取所有数据，但我只需要来自所提供源的某些数据

HTML

<tr ng-repeat="val in values ">
    <td ng-bind="$index"></td>
    <td ng-bind="val.rec">ED1500322</td> 
    <td>working</td>
    <td ng-bind="val.result">I am going to School</td>
    <td>
      <div class="radio">
        <input ng-model="val.iscorrect" value="yes" type="radio">
        <label for="opt1">yes</label>
        <input ng-model="val.iscorrect" value="no" type="radio">
        <label for="opt10">no</label>
      </div>
    </td>
  </tr>

数据

$scope.values = [{
    name: "John",
    rec:234,
    iscorrect: ''
  }, {
    name: "Paul",
    rec:44,
    iscorrect: ''
  }, {
    name: "George",
    rec:2664,
    iscorrect: 'no'
  }, {
    name: "Ringo",
    rec:124,
    iscorrect: 'yes'
  }];

我们可以看到我在 iscorrect=""中有特定的值。我只希望相应的值在我的 $scope.values 和 html 中

感谢任何帮助获取 iscorrect=""的数据...

Answer 1

所以你只想显示那些 where iscorrect=''?

试试这个:

<tr ng-repeat="val in values" ng-if="!val.iscorrect">

修改了答案以去除过滤器，并使用更清洁的 ng-if 代替 plnkr
