Question

我是角色新手，我试图从表中推送某个选中的复选框并更新为新数组

<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>

我们可以看到复选框存在，当选中复选框时，我想将其推入新数组

我希望新数组只选中复选框

我知道这可以通过索引来实现，不知道该怎么做

感谢

提供任何仅选中复选框的帮助

Answer 1

你可以搭载ng-change。它看起来像这样

的javascript

$scope.DoChange = function(val) { array.push(val)};

HTML

<input ng-model="val.iscorrect" value="yes" type="radio" ng-change="DoChange(val)">

我更新了plunkr

如果您希望将所有选定项目推送到$ scope.results。从您的plunker获取的以下修改代码将起作用：

 var ngApp = angular.module('app', []);
 ngApp.controller('ctrl', function($scope) {

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

     $scope.result = []
     $scope.getResult = function() {
         $scope.result = $scope.values.filter(function(res) {
             return res.iscorrect.length > 0;
         })
     }

 });

Answer 3

在这里你应该这样做只有改变这一点。

<tr ng-repeat="(ind,val) in values track by $index">
    <td ng-bind="$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="values[ind].iscorrect" value="yes" type="radio">
        <label for="opt1">yes</label>
        <input ng-model="values[ind].iscorrect" value="no" type="radio">
        <label for="opt10">no</label>
      </div>
    </td>   
</tr>

Answer 4

默认情况下，复选框/单选按钮返回true或false。

这意味着您只需在单选按钮上添加ng-click指令，并使用$ index和您希望存储的任何其他数据传递ng-model。

示例

 <input ng-model="val.iscorrect" data-value="no" type="radio" ng-click="pushValue($index,val.iscorrect)">

仅供参考我会假设数据值=＆＃34;否＆＃34;连接到false所以不需要通过它..

希望这有帮助
