jquery - Angular: deferred var is undefined in then-method -

-

within angular.js code i'm calling yahoo yql api get/jsonp , response. there 2 problems.

  1. it calls error method instead of success. why?
  2. the deferred variable seems undefined within error-function. why?

you can find jsfiddle here. based on ajax example.

function defaultctrl($log, $scope, $http, myservice) {      var promise = myservice.getsuggestions('yahoo');      promise.then(           function(payload) {                $log.info('receiving data', payload);               $scope.test = payload;               $log.info('received data', payload);           },           function(errorpayload) {               $log.error('failure loading suggestions', errorpayload);           });     }  angular.module('mymodule', []) .factory('myservice', function ($http, $log, $q) {     return {         getsuggestions: function (symbol) {                          var deferred = $q.defer();              $http.jsonp("http://d.yimg.com/autoc.finance.yahoo.com/autoc", {                 cache: true,                 params: {                      callback: "yahoo.finance.symbolsuggest.sscallback",                                    query: symbol                 }             })             .success(function(data) {                 deferred.resolve(data);             })             .error(function(msg, code) {                 $log.error("error");                 deferred.reject(msg);  // <---- error occurs here!                 $log.error(msg, code);             });              var yahoo = window.yahoo = {finance: {symbolsuggest: {}}};             yahoo.finance.symbolsuggest.sscallback = function (data) {                 $log.info("received data", data);             }; // yahoo.finance                   return deferred.promise;         }     } });

here working example. have pass callback function in promise callback , have callback reject or resolve promise. think problem code posted that, after execution of callback success , error both executed , result undefined var resolved/rejected.

var myapp = angular.module('mymodule', []);  myapp.controller('defaultctrl', function ($log, $scope, $http, myservice) {      var promise = myservice.getsuggestions('yahoo');      promise.then(      function (payload) {         $log.info('receiving data in defaultctrl', payload);         $scope.test = payload;     },      function (errorpayload) {         $log.error('failure loading suggestions', errorpayload);     });  });   myapp.factory('myservice', function ($http, $log, $q) {     return {         getsuggestions: function (symbol) {              var yahoo = window.yahoo = {                 finance: {                     symbolsuggest: {}                 }             };             yahoo.finance.symbolsuggest.sscallback = function (data) {                 $log.info("received data in sscallback", data);                 deferred.resolve(data);             }; // yahoo.finance                   var deferred = $q.defer();              $http.jsonp("http://d.yimg.com/autoc.finance.yahoo.com/autoc", {                 cache: true,                 params: {                      callback: "yahoo.finance.symbolsuggest.sscallback",                                    query: symbol                 }             })             .then(yahoo.finance.symbolsuggest.sscallback);              return deferred.promise;         }     } });

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
