Is there some way I can show custom exception messages as an alert in my jQuery AJAX error message?
For example, if I want to throw an exception on the server side v
This is what I did and it works so far in a MVC 5 application.
Controller's return type is ContentResult.
public ContentResult DoSomething()
{
if(somethingIsTrue)
{
Response.StatusCode = 500 //Anything other than 2XX HTTP status codes should work
Response.Write("My Message");
return new ContentResult();
}
//Do something in here//
string json = "whatever json goes here";
return new ContentResult{Content = json, ContentType = "application/json"};
}
And on client side this is what ajax function looks like
$.ajax({
type: "POST",
url: URL,
data: DATA,
dataType: "json",
success: function (json) {
//Do something with the returned json object.
},
error: function (xhr, status, errorThrown) {
//Here the status code can be retrieved like;
xhr.status;
//The message added to Response object in Controller can be retrieved as following.
xhr.responseText;
}
});
