javascript - No 'Access-Control-Allow-Origin' header is present. Origin is therefore not allowed access -


edit: no jsonp! yes know cors handled server , yes server support it. issue on side.

i trying use mediawiki api browser. sending request through xmlhttprequest due cors issues it's not working. getting following message browser after receives response:

xmlhttprequest cannot load https://en.wikipedia.org/w/api.php?format=json&action=query&list=search&srsearch=oculus&utf8. no 'access-control-allow-origin' header present on requested resource. origin 'http://127.0.0.1:8000' therefore not allowed access.

i understand why getting issue not know how can solve browser/javascript side.

code:

xmlhttp.open("get","https://en.wikipedia.org/w/api.php?format=json&action=query&list=search&srsearch=" + subreddit + "&utf8",true); xmlhttp.setrequestheader("content-type", "application/json; charset=utf-8"); xmlhttp.send();

some of things i've tried:

xmlhttp.setrequestheader('access-control-allow-origin', 'http://localhost'); xmlhttp.setrequestheader('access-control-allow-methods', 'get, post, options, put, patch, delete'); xmlhttp.setrequestheader('access-control-allow-headers', 'x-requested-with,content-type'); xmlhttp.setrequestheader('access-control-allow-credentials', true) xmlhttp.setrequestheader("content-type", "application/json; charset=utf-8");

and setting parameter origin in url or setrequestheader returned invalid/bad origin, denied.

you can use jsonp.

<script src='https://en.wikipedia.org/w/api.php?format=json&action=query&list=search&srsearch=oculus&utf8&callback=callbackname'></script> <script>     function callbackname(data){        //you can response data here     } </script>

if use jquery.

$.getjson('https://en.wikipedia.org/w/api.php?format=json&action=query&list=search&srsearch=oculus&utf8&callback=?', function(data){     //you can response data here })

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
