javascript - how to get result of getjson promise inside $.when function? -


using following code try data of 2 getjson calls array when both getjson called completed. code give me error:

resultfromurl1.feed undefined var entry1 = resultfromur11.feed.entry;

i looked @ f12 saw both getjson executed no data put array! how fix error ? furthermor should use $.when(url1promise, url2promise).then or $.when(url1promise, url2promise).done ? 

<javascript>      var files = new array();          function pushtoarray() {              //first getjson call             var url1 = "https://spreadsheets.google.com/feeds/list/xxxxx/xxxxx/public/values?alt=json";             var url1promise = $.getjson(url1, function (data) {                 console.log("url1 success");             });//end of ajax call              //second getjson call             var url2 = "https://spreadsheets.google.com/feeds/list/xxxxx/xxxxx/public/values?alt=json";             var url2promise = $.getjson(url2, function (data) {                 console.log("url2 success");             });//end of function              $.when(url1promise, url2promise).then(function (resultfromurl1, resultfromurl2) {                 var entry1 = resultfromurl1.feed.entry;                 var entry2 = resultfromurl2.feed.entry;                  var entry = entry1.concat(entry2);                  $(entry).each(function () {                     // column names name, age, etc.                     count++;                     files.push({ url: this.gsx$url.$t, filename: this.gsx$name.$t });                             alert(files.length);                             print_r(files);                             console.log(files);                   });               });         }//end of function              </javascript>             <body onload="pushtoarray()">

jquery ajax functions bit of pain use $.when(). is in resultfromurl1 array of 3 values this: [data, textstatus, jqxhr].

so, need change to:

var entry1 = resultfromurl1[0].feed.entry; var entry2 = resultfromurl2[0].feed.entry;

in addition, should add error handler $.when().then() construct can see if errors occurred in getjson() calls.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
