如何将模型值作为javascript函数参数从asp.net mvc Html助手中传递出来,如Html.Radio？

public class MyViewModel
{
    public string SelectedValue { get; set; }
    // 其他模型属性
}

public ActionResult MyAction()
{
    MyViewModel model = new MyViewModel();
    // 设置模型属性
    return View(model);
}

@model MyViewModel

@using (Html.BeginForm())
{
    @Html.RadioButtonFor(m => m.SelectedValue, "Value1", new { onclick = "myFunction('" + Model.SelectedValue + "')" })
    @Html.RadioButtonFor(m => m.SelectedValue, "Value2", new { onclick = "myFunction('" + Model.SelectedValue + "')" })
    @Html.RadioButtonFor(m => m.SelectedValue, "Value3", new { onclick = "myFunction('" + Model.SelectedValue + "')" })
}

<script>
    function myFunction(selectedValue) {
        // 在此处使用传递的参数
        console.log(selectedValue);
    }
</script>
