javascript - JSON data fetching through Yahoo! Placefinder -

-

i trying retrieve information placefinder api. code takes information text box , sends yahoo on button click. 

            function codeaddress(){             var address = document.getelementbyid("address").value;             var requesturl = "http://where.yahooapis.com/geocode?q="+address+"&flags=j&callback=ws_results&output=json";             jsonobject = new xmlhttprequest();             jsonobject.open( "get", requesturl, false );             jsonobject.send( null );             return jsonobject;             document.getelementbyid("jlatitude").innerhtml=jsonobject.latitude;             alert(document.write("jlatitude"));         }

firebug tells me data returned, yet cannot display want in troubleshooting popup. placefinder returns when request geocoding maryland.

{"resultset":{"version":"1.0","error":0,"errormessage":"no error","locale":"us_us","quality":10,"found":2,"results":[{"quality":49,"latitude":"39.466626","longitude":"-93.709069","offsetlat":"39.466626","offsetlon":"-93.709069","radius":700,"name":"","line1":"","line2":"roads, mo","line3":"","line4":"united states","house":"","street":"","xstreet":"","unittype":"","unit":"","postal":"","neighborhood":"roads","city":"norborne","county":"carroll county","state":"missouri","country":"united states","countrycode":"us","statecode":"mo","countycode":"","uzip":"64668","hash":"","woeid":2482523,"woetype":7},{"quality":49,"latitude":"39.080130","longitude":"-82.537394","offsetlat":"39.080130","offsetlon":"-82.537394","radius":700,"name":"","line1":"","line2":"roads, oh","line3":"","line4":"united states","house":"","street":"","xstreet":"","unittype":"","unit":"","postal":"","neighborhood":"roads","city":"wellston","county":"jackson county","state":"ohio","country":"united states","countrycode":"us","statecode":"oh","countycode":"","uzip":"45692","hash":"","woeid":2482522,"woetype":7}]}}

my alert box not appear, data stored.

thanks

i think you've got simple problem in javascript code example - after receiving data yql, have return jsonobject; means following lines never executed.

to troubleshoot , confirm, write console log upon return, like:

function codeaddress(){     var address = document.getelementbyid("address").value;     var requesturl = "http://where.yahooapis.com/geocode?q="+address+"&flags=j&callback=ws_results&output=json";     jsonobject = new xmlhttprequest();     jsonobject.open( "get", requesturl, false );     jsonobject.send( null );     console.log( jsonobject.responsetext ); }

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
