Angular: 通过 ng-attr-id 获取 ng-model？

Question

有没有办法通过 ng-attr-id 获得 ng-model 值？

我正在制作一个Comment/Reply框，我想获取当前回复的值。

这是我的html--

<div class="comments-list" ng-show="CommentsLoaded">
    <ul>
        <li ng-repeat="comment in comments">
            <div>
                {{comment.content}}
            </div>
            <div ng-click="showReply(comment.id)">
                Reply
            </div>
            <div ng-class="hideReply" ng-attr-id="{{'reply-'+comment.id}}">
                <textarea ng-model="replytxt" ng-attr-id="{{'replytxt-'comment.id}}"></textarea>
                <div class="form-group">
                    <button type="button" ng-click="sendReply(comment.id)">
                        Publier
                    </button>
                </div>
            </div>
        </li>
    </ul>
</div>

这里是angularjs--

$scope.sendReply = function(commentId){
    var elm = document.getElementById('replytxt-'+commentId);
    console.log(elm);
}

以上函数在控制台中显示：

<textarea ng-model="replytxt"  ng-attr-id="{{'replytxt-'+comment.id}}" class="ng-pristine ng-valid ng-touched" id="replytxt-31"></textarea>

您不需要通过选择器检索元素值。单击时在 sendReply 函数本身内传递 replytxt 值。

ng-click="sendReply(comment.id, replytxt)"

$scope.sendReply = function(commentId, replytxt){

建议：与其让 replytxt 像 ng-model 那样独立存在，不如把它放在评论级别属性上，比如 [=17] =]，这样您就不需要负责将 replytxt 值单独传递给服务器。

ng-click="sendReply(comment)"

代码

$scope.sendReply = function(comment){
    console.log(comment.id, comment.replytxt);
}
