javascript - CORS error for firefox and chrome -


i have problem regarding cors error in code,the .js file run gives error chrome , firefox not on ie. have been suggested add response headers confused add it.please help

xhr.open(method, url, true);

i tried adding xhr.setrequestheader("access-control-allow-origin:*"); it,will work?

do not add xhr.setrequestheader("access-control-allow-origin:*") @ client side code.

to allow cross domain request, server needs add access-control-allow-origin header response.

the value of access-control-allow-origin should domain name of request allowed or * if origin allowed.

access-control-allow-origin: http://domain1.com or

access-control-allow-origin: *

if calling web api method refer below tested code , working rest api.

client side code ajax call:

function callajax() {        var xhr = new xmlhttprequest();  xhr.open("get", "http://localhost:54118/api/values", true);  xhr.onload = function () {      console.log(xhr.responsetext);      alert("sucuess");  };  xhr.send();  }

server side changes :

in web api project have add following configuration in web.config file. under system.webserver section add following

 <httpprotocol>        <customheaders>          <add name="access-control-allow-origin" value="*"/>        </customheaders>      </httpprotocol>

this allow domain access resource.

hope helpful :)

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
