如何使用Ajax.BeginForm的onSuccess和OnFailure方法？ [英] How to Use Ajax.BeginForm OnSuccess and OnFailure Methods?

问题描述

我用这个Ajax.BeginForm

I using this Ajax.BeginForm

    <% using( Ajax.BeginForm( "Create","Mandate",
                       new AjaxOptions( ) {
                           OnSuccess = "GoToMandates",
                           OnFailure = "ShowPopUpError"
                       } ) ) {%>

<% } %>

什么我需要在CONTROLER写抓住这个OnSucces和OnFailure。

What do I need to write in the controler to catch this OnSucces and OnFailure.

由于的onSuccess我需要证明成功的消息

Because OnSuccess I need to show Success message

OnFailure我需要证明othere消息。

OnFailure I need to show othere message.

在我的控制器

Public ActionResult GetSomething(FromCollection collection)
{
     if(exists == null)
     {
          //OnSuccess
     }
     else
     { 
         //OnFailure
     }
}

可以anydboy帮我..怎么抓呢？

推荐答案

本的onSuccess和OnFailure看起来像他们期待的JavaScript回调函数。

The OnSuccess and OnFailure looks like they are expecting javascript callback functions.

<script type="text/javascript">
    function handleError(ajaxContext) {
    var response = ajaxContext.get_response();
    var statusCode = response.get_statusCode();
    alert("Sorry, the request failed with status code " + statusCode);
    }
</script>

<%= Ajax.ActionLink("Click me", "MyAction",
new AjaxOptions { UpdateTargetId = "myElement", OnFailure = "handleError"}) %>

从临ASP.NET框架页例425

ASP.NET AjaxOptions类

新增控制器为例

要做到这一点是我在这里得到了什么，但我建议寻找到强类型MVC的看法使用某种视图模型，并可能考虑使用jQuery为您阿贾克斯simpliest方式。随着中说你这个应该有希望的工作。

The simpliest way to do this would be what I've got here but I recommend looking into strongly typed mvc views using some kind of ViewModel and maybe look into using jQuery for your ajax. With that said this should hopefully work for you.

if (exists)
{
  ViewData["msg"] = "Some Success Message";
}
else
{
  ViewData["msg"] = "Some Error Message";
}

return View();

在你看来

<div id="myResults" style="border: 2px dotted red; padding: .5em;">
    <%: ViewData["msg"]%>
</div>
