javascript - callback function not executed in jquery -


i learning send request in jquery. following block of code makes request. checked in servlet request made callback function not invoked. can't figure out problem.

$.get('http://localhost:8080/pc_controlo/statusservlet?id=1001', function(data){ alert('hello'); });

and browsers network tab shows this

[01:21:26.759] http://localhost:8080/pc_controlo/statusservlet?id=1001 [http/1.1 200 ok 1ms]

+

this have done in servlet.

printwriter out = response.getwriter();             out.write("working");             out.close();

and .fail(msg){ alert('failed message:'+json.stringify(msg)); gave following message

failed message: {"readystate":0,"responsetext":"","status":0,"statustext":"error"}

thanks in advance :).

i did few tests replacing url google.com, , encountered same problem. noticed if use .done(), .always(), , .error(), might have better luck figuring out going on. check out jsfiddle:

http://jsfiddle.net/gqfsd/

$.get('http://www.google.com/') .done(function(data) {     alert('success! data loaded: ' + data);    }) .fail(function(msg) {     alert('failed message: ' + json.stringify(msg)); }) .always(function() {     alert('always alerts'); });

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
