Angularjs通过check单选按钮将数据绑定到其他表，并在单击按钮后更新

根据你提供的一点信息，我想尝试一下：

您能否在控制器中定义$scope和函数？您想实现什么？{{song.name}{{song.artist}{{song.genre}{{song.price}}我想使用ngmodel的单选按钮，当我点击单选按钮时，数据加载到其他表。我更新数据，但只在单击按钮更新后更新，而不是直接绑定除非我误解了您的意图，angular.copy不会直接绑定，而是复制对象$scope.edit_song=歌曲将是直接绑定。我尝试使用$scope.selectedSong[index]=angular.copy$scope.editSong；但是我不知道为什么当我点击单选按钮时，它仍然不显示数据，数据没有加载到另一个表中。你看了我的小提琴吗$scope.selectedSong不需要[索引]

<table>
    <tr>
    <td><input type="radio" name="groupName" value="song" ng-model="$parent.selectedSong"/></td>
    <td>{{song.name}}</td>
    <td>{{song.artist}}</td>
    <td>{{song.genre}}</td>
    <td>{{song.price}}</td>
    <td>
        <input type="button" value="Delete" ng-click="deleteItem(song.id)" /> 
    </td>

    <td>
        <input type="button" value="View" ng-click="go('OneSong', song)"  />
    </td>

</tr>
</table>

<table border="1">

    <tr><td id="Td1">Correct Table</td></tr>
    <tr>
        <td>Name: </td>
        <td><input type="text" ng-model="editItem.name"/></td>
    </tr>
    <tr>
        <td>Artist: </td>
        <td><input type="text" ng-model="editItem.artist"/></td>
    </tr>
    <tr>
        <td>Genre: </td>
        <td><input type="text" ng-model="editItem.genre"/></td>
    </tr>
    <tr>
        <td>Price: </td>
        <td><input type="text" ng-model="editItem.price"/></td>
    </tr>
    <tr>
        <td colspan="2">
            <!--<input type="button" value="Insert "ng-click="addItem()"/>-->
                <a href="#/AddNewSong">Add New Song</a>
                <input type="button" value="Update" ng-click="updateItem()"/>  

            <input type="button" value="Cancel" ng-click="cancel()"/>  
        </td>
    </tr>
</table>

var app = angular.module('songApp',[]);

app.controller('SongCtrl',function($scope) {
    $scope.edit_song = {};
    $scope.song = [
        {name:'Heartbreaker',artist:'Led Zeppelin',genre:'Rock',price:'.99'},
        {name:'War Pigs',artist:'Black Sabbath',genre:'Rock',price:'.99'}
    ];

    $scope.applySong = function(song) {
        $scope.edit_song = angular.copy(song);
        $scope.edit_song.song_index = $scope.song.indexOf(song);
    };

    $scope.saveSong = function() {
        var idx = $scope.edit_song.song_index;
        $scope.song[idx] = $scope.edit_song;
        $scope.cancelSong();
    };

    $scope.cancelSong = function() {
        $scope.edit_song = {};  
    };
});
