MVC中的Ajax表单验证

Question

I have an Ajax form that I need to hit a JavaScript function on failure, like so:

using (Ajax.BeginForm("UpdateStages", new AjaxOptions
{
    HttpMethod = "POST",
    OnSuccess = "refreshSearchResults('" + @Model.First().ItemCode + "')",
    OnFailure = "showError"
}))

With the showError function taking the Ajax context response and appending it to a div , like so:

function showError(ajaxContext) 
{
    var response = ajaxContext.responseText;
    response = $($.trim(response));
    var itemVersion = response.filter("div")[0].innerHTML.trim().toString();
    var error = response.filter("p")[0].outerHTML.toString();
    $("#" + itemVersion.replace(".", "") + "-UpdateStagesResults").empty();
    $(error).appendTo("#" + itemVersion.replace(".", "") + "-UpdateStagesResults");
}

In order for the OnFailure to be called I have in my MVC controller ActionResult , when an error occurs:

Response.StatusCode = (int)HttpStatusCode.BadRequest;
return PartialView();

which returns a PartialView with the error message in the ViewBag . This works fine when running locally, the error message is sent to the showError function and then the error is appended to the page.

The problem is that when I put the application onto a live server (IIS7), the Ajax context is just

Bad Request

and for example is not:

<p>You have not entered a valid date.</p>
<div style="display:none;">V7.0  </div>

Any help would be great!

I've had this,

in IIS7 the default error settings are to show detailed error messages locally only., your view is replaced with the default for the status code.

If you want to see your custom errors, add this into your web.config

<system.webServer>
    <httpErrors errorMode="Detailed" />
</system.webServer>

that should sort it
