c# - ASP.Net MVC Ajax.BeginForm OnComplete 在 Razor View 中传递 c# 参数

Question

我在 MVC c# Razor View 中有以下代码:

@{string url = "/Projects/_MonthRangesScriptsPartial";}
@using (Ajax.BeginForm(
  "_MonthRanges", 
  "Projects", 
  new { id = ViewBag.InputResourceID }, 
  new AjaxOptions { 
    HttpMethod = "POST", 
    UpdateTargetId = "MonthRanges", 
    InsertionMode = InsertionMode.Replace,
    OnComplete = "updategraphArrayScript(@url,@ViewBag.InputResourceID)"
  }))

代码几乎完美运行，但我想将 c# 变量解析为其在 OnComplete 行中的值。

也就是说，Razor 引擎应该将代码解析为(例如):

<form action="/Projects/_MonthRanges/55" 
  data-ajax="true" data-ajax-complete="updategraphArrayScript(/Projects/assets,55)"
  ...>

而不是:

<form action="/Projects/_MonthRanges/55" 
  data-ajax="true" data-ajax-complete="updategraphArrayScript(@url,@ViewBag.InputResourceID)"
  ...>

只需创建另一个变量字符串:

@{
    string url = "/Projects/_MonthRangesScriptsPartial";
    string onComplete = String.Format("updategraphArrayScript({0}, {1})", url, ViewBag.InputResourceID);
}

@using (Ajax.BeginForm(
  "_MonthRanges", 
  "Projects", 
  new { id = ViewBag.InputResourceID }, 
  new AjaxOptions { 
    HttpMethod = "POST", 
    UpdateTargetId = "MonthRanges", 
    InsertionMode = InsertionMode.Replace,
    OnComplete = @onComplete
  }))
