asp.net-mvc – 根据MVC中第一个dropdownlistfor的值启用第二个

我有三个DropDownLists.如果选择了第一个DropDownList中的特定值,则应启用第二个Dropdownlist.例如,如果选择了“播放器3”,则应启用另外两个DropDownList,但是,如果选择“播放器2”,则应禁用最后一个DropDownList,并启用第二个DropDownList.

我怎么能轻松做到这一点？我首先使用的是MVC 3 EF模型.
这是我的观点中的代码：

<p>Player</p>
     <div class="editor-field">
        @Html.DropDownListFor(m => m.PlayerName,Model.SubjectTypes,"Choose player",new { @class = "selectstyle" })
        @Html.ValidationMessageFor(model => model.PlayerName)
    </div>

    <p>Position</p>
    <div class="editor-field">
        @Html.DropDownListFor(model => model.PositionName,Model.Consultants,"Choose Position",new { @class = "selectstyle" })
        @Html.ValidationMessageFor(model => model.ContactPerson)
    </div>

    <p>Team</p>
    <div class="editor-field">
        @Html.DropDownListFor(model => model.TeamName,Model.Teams,"Choose Team",new { @class = "selectstyle" })
        @Html.ValidationMessageFor(model => model.ContactPerson)
    </div>

$(function() {
    $('#PlayerName').change(function() {
        var value = $(this).val();
        if (value == 'Player3') {
            $('#PositionName,#TeamName').removeAttr('disabled');
        } else if (value == 'Player2') {
            $('#PositionName').removeAttr('disabled');
            $('#TeamName').attr('disabled','disabled');
        }
    });
});
