@ Html.RadioButtonFor回发

Question

我想在选择单选按钮后立即更新表单上的其他控件。

单击单选按钮后，如何让这些控件调用控制器。单独的提交（actionLink）按钮不合适。

我的代码是

<label for="ApplicationTypes_Single">On your own?</label>
@Html.RadioButtonFor(x => x.ApplicationType, "Single", new { id = "ApplicationTypes_Single" })

<label for="ApplicationTypes_Joint">With someone else?</label>
@Html.RadioButtonFor(x => x.ApplicationType, "Joint", new { id="ApplicationTypes_Joint" })

依赖于该选择的控件是

@if(Model.ApplicationType == AffordabilityPage1.ApplicationTypes.Joint)
{
    @Html.LabelFor(model => model.SecondAge)
    @Html.EditorFor(model => model.SecondAge)
}

非常感谢您给出的任何提示。

你需要javascript才能实现这一目标。例如，如果您使用的是jquery，则可以订阅这些单选按钮的更改事件并采取一些操作：

$(function() {
    $(':radio[id^="ApplicationTypes"]').change(function() {
        var value = $(this).val(); // will equal Single or Joint
        // Depending on what you are trying to achieve either send an AJAX request
        // or force the submission of some form in order to send the new value to the server
    });
});
