200 OK but parsererror?

in Using jQuery • 13 years ago

I have used jquery for ajax query to my asp.net server. works fine.

today I try to refector my code and got this parsererror.

I inspect my xmlrequest text and looks like this.

<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">
[{"original":{"original":null,"MonitorId":"64ca8ce7-6b3b-4458-9d20-6cd731fc01d7","FullName":"TestName","ShortName":"Test","SortIndex":1,"OwnerUserId":"7c43898c-2fc0-474d-92d7-9c47ff3b822a","LatitudeWGS84":24.325,"LongitudeWGS84":120.7536,"Altitude":13.65,"IsDefaultMonitor":false,"MonitorGroupId":"f9645bf3-a961-480d-b17a-4fa6755fbfae","ShareOptionId":3,"IsDisabled":false,"LoggerId":"bb7b93f0-7d91-483a-871a-0529a5317929"},
"MonitorId":"64ca8ce7-6b3b-4458-9d20-6cd731fc01d7","FullName":"TestName","ShortName":"Test","SortIndex":1,"OwnerUserId":"7c43898c-2fc0-474d-92d7-9c47ff3b822a","LatitudeWGS84":24.325,"LongitudeWGS84":120.7536,"Altitude":13.65,"IsDefaultMonitor":false,"MonitorGroupId":"f9645bf3-a961-480d-b17a-4fa6755fbfae","ShareOptionId":3,"IsDisabled":false,"LoggerId":"bb7b93f0-7d91-483a-871a-0529a5317929"}]
</string>

which looks just fine to me. I am going to parser it using a json parser later in my success callback.

So what is this parsererror about? it keeps me from my success callback.

if you are returning json inside of an xml doc, why not just return the json and set the ajax datatype to json, jquery will turn it into a javascript object in your success callback.

Edit: Generally, a parse error when dealing with XML means there is something wrong with the xml, try opening the xml in internet explorer, it'l tell you if it thinks it is valid or not. or you can plug it into any of the other xml validators

Edit2: http://validator.w3.org/check shows your xml as valid, not sure what to look at after that, 200 response means the page was returned correctly, but parse error, it didnt get parsed correctly. I'd still suggest returning json as json rather than xml

I figure it out, that is really strange.

I am calling a method with no argument like this.

$.ajax({
type: "POST",
url: "some url",
cache: false,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: InitMarker,
error: AjaxFail
});

This will gives you parsererror. but there is nothing wrong with your return value.

If you need no argument, should invoke the ajax like this.

$.ajax({
type: "POST",
url: "some url",
cache: false,
contentType: "application/json; charset=utf-8",
data: "{}",
dataType: "json",
success: InitMarker,
error: AjaxFail
});

you have your dataType set to json, but your data is really xml. your dataType option needed to be set to xml to accept xml.
