您可以使用以下选项，而不是引发异常：
然后可以从textStatus变量访问消息。一种方法是将服务器上操作的返回类型更改为JsonResult
，然后将方法调用包装在try catch
中。然后，这允许您在发生异常时以json的形式返回异常消息：
return new HttpStatusCodeResult(500, "Could not delete category. This category has data associated with it. Please delete the associated data first.");
public JsonResult Delete(long[] fooIds)
{
try
{
//make method calls
return Json(new {});
}
catch(Exception ex)
{
return Json(new {exception = ex.message});
}
}
可能重复。@Zabavsky：我对如何解决处理错误情况的一般问题并不感兴趣。我对处理ASP.NET引发的异常的其他方法也不感兴趣。我知道所有的选择。我只是想知道序列化异常在jQuery XHR对象中会转换成什么。似乎XHR并不关心返回的响应的细节，在本例中，正好是一个HTML DOM，我感兴趣的值被嵌入到DOM中，我不想编写DOM解析例程来获取该值。如果您编写try catch
，那么在ajax中，每次都会调用OnSuccess
方法<永远不会调用code>OnError return new HttpStatusCodeResult(500, "Could not delete category. This category has data associated with it. Please delete the associated data first.");
public JsonResult Delete(long[] fooIds)
{
try
{
//make method calls
return Json(new {});
}
catch(Exception ex)
{
return Json(new {exception = ex.message});
}
}
