Question

我使用knockoutJS，当我使用“fromJS”时，我有以下错误

TypeError：无法调用未定义的方法'fromJS'

我的JavaScript代码

 <script src="../../Scripts/jquery-1.8.3.js" type="text/javascript"></script>
 <script src="../../Scripts/knockout-2.1.0.js" type="text/javascript"></script>


 <script type="text/javascript">
     $(document).ready(function () {
         var PersonModel = function (data) {
             ko.mapping.fromJS(data, {}, this);
         };

         var data = $.getJSON("http://localhost:40913/candidate/index/1", function (data)
         {
             viewModel = new PersonModel(data);
             ko.applyBindings(viewModel);
         }
         );
     });
 </script>

JSON输出
