javascript - 在 Ajax.BeginForm 的确认对话框中添加对象 routedValue

Question

我想要的是在用户提交表单时添加一个对象路由值（ajax.beginform）

根据用户在 ConfirmDone 函数中选择的内容，我想添加一个整数（SaveOption）

但我真的不知道该怎么做。

调用了 confirmdone 函数，但就是这样，我的控制器操作没有被调用。我可能需要退货？

一些代码：表格的开头

@using (Ajax.BeginForm("CreateFunctiebeschrijvingPartial", "Functiebeschrijving", new     AjaxOptions { UpdateTargetId = "Functiebeschrijving", OnBegin = "return ConfirmDone()", OnSuccess = "handleSuccess" }, new {@id = frmID}))
{

确认完成功能

function ConfirmDone() {
    if (confirm("This form saves default as Concept, would you like to save it as completed? 1 = Completed, 2 = Concept")) {
        //option 1: save as completed
        $('#frmID').attr("SaveOption", 1);                        
    }
    else {
        //Option 2: save as concept
    }
}

我的控制器动作的开始

//
// POST: /FunctieBeschrijving/CreateFunctiebeschrijvingPartial
[HttpPost]
public ActionResult CreateFunctiebeschrijvingPartial(NieuweFunctiebeschrijvingViewModel nfvm, int SaveOption)
{

当我不使用确认功能时，一切都按原样发布！

Answer 1

function addDataToUrl(url, name, value){
    var sep = url.indexOf('?') === -1 ? '?' : '&';
    return url + sep + name + '=' + value;   
}

function ConfirmDone() {
    var form = document.getElementById('frmID');
    if (confirm("This form saves default as Concept, would you like to save it as completed? 1 = Completed, 2 = Concept")) {
        //option 1: save as completed
        form.setAttribute('action', 
        addDataToUrl(form.getAttribute('action'), 'SaveOption', '1'));                   
    }
    else {
        // Option 2: save as concept
    }
}
