我正在创建一个简单的用户注册表。用户可以注册为公司或个人。下面是使用RadioButtonFor html helper的Registration表单的相关视图。我已经定义了在JavaScript中使用的id属性：

@model LayoutTest.ViewModels.ProjectUser
    <script>
    $(function () {
    $("#Class_UserType").change(function(){
        var value = $(this).val();
        if (value == 1) {
            $('#Person').hide();
        }
        else if (value == 2) {
            $('#Company').hide();
        }
      });
    });
    </script>
    @using (Html.BeginForm("Create", "Project", FormMethod.Post, new { enctype = "multipart/form-data" }))
    {
   @Html.ValidationSummary(true)
   <fieldset>
   <div class="new_row">
        <div class="editor-label">
            @Html.LabelFor(model => Model.UserType)
        </div>
        <div class="editor-field">
            <div class="editor-field">
                @Html.RadioButtonFor(model => model.UserType, (int)UserType.Company, new { @id= "Class_UserType" }) Company
                @{Html.ValidateFor(model => model.UserType);}
            </div>
            <div class="editor-field">
                @Html.RadioButtonFor(model => model.UserType, (int)UserType.Individual, new { @id = "Class_UserType" }) Individual 
                @{Html.ValidateFor(model => model.UserType);}
            </div>
        </div>
    </div>
    <div class="Company">
          HTML Tags inside
    </div>
    <div class="Person">
        HTML Tags inside
    </div>

字符串
当正确工作时，此代码应隐藏相应的div Company/Person。我已经看了无数的样品，但不能弄清楚我在这里做错了什么！如有任何帮助，我们将不胜感激。
以下是相关的html输出：

<div class="new_row">
        <div class="editor-label">
            <label for="UserType">*User Type</label>
        </div>
        <div class="editor-field">
            <div class="editor-field">
                <input data-val="true" data-val-number="The field *User Type must be a number." data-val-required="The *User Type field is required." id="Class_UserType" name="UserType" type="radio" value="1" /> Company
            </div>
            <div class="editor-field">
                <input checked="checked" id="Class_UserType" name="UserType" type="radio" value="2" /> Individual 
            </div>
        </div>
    </div>
