我的角度控制器

app.controller("MyController", function ($scope, MyServices,$http) {

// Get All Comments
GetAllComments();
function GetAllComments() {
    var getData = MyServices.getComments();

    getData.then(function (cmnt) {
        $scope.Comments = cmnt.data;
    },

    function () {
        alert('Error in getting Comments');
    });
};

// Add New Comment
$scope.AddComment = function () {

    var Comment = {
        CommentText: $scope.CommentText

    };
    var getData = MyServices.AddCmnt(Comment);

   getData.then(function (ResultMsg) {

        GetAllComments();
        alert(ResultMsg.data);
    });

    ClearFields();
    $scope.refresh();

};

// Edit The Comment
$scope.EditComment = function () {

    Comment =
        {
            Id: Comment.Id,
            CommentText: $scope.UpdateCommentText

        }
    alert(Comment.CommentText);
    //var getData = MyServices.getCommentById(Comment.Id);

    var getData = MyServices.EditCmnt(Comment);

    getData.then(function (ResultMsg) {
        alert(ResultMsg.data);
        GetAllComments();
    });


};

// Delete The Comment
$scope.RemoveComment = function (Comment) {
    var getData = MyServices.DeleteCmnt(Comment);

    getData.then(function (ResultMsg) {
        alert(ResultMsg.data);
        GetAllComments();
    },
    function () {
        alert('Error in Deleting Comment');
    });
}

//Clear Fields After Comment Addition
function ClearFields() {
    $scope.CommentText = "";
    angular.forEach(angular.element("input[type='file']"), function (inputElem) {
        angular.element(inputElem).val(null);
    });
};

}）;

在索引页面中的comment.commenttext是可编辑的文本，点击编辑时会出现数据库，会有一个可编辑的文本框，在点击保存按钮后编辑文本后我无法获得编辑文本的值在editcomment部分中检索已编辑文本的值？我尝试了$ scope.Comment.commenttext但它未定义.. 请事先帮助我..

你有一个双重绑定：

<h3>
<text 
    style="color:mediumpurple;" 
    e-form="rowform" 
    data-ng-model="UpdateCommentText" 
    editable-text="Comment.CommentText"
    >
    {{Comment.CommentText || 'Empty'}}
</text>
</h3>

所以基本上你看到什么是数据-ng-model绑定，而不是{{}}中的表现试着获得UpdateCommentText值。也许这有帮助。
