javascript - angularjs getting data from a url -

-

i want json data url , assign variable. use service looks this

app.service('dataservice', function($http) {   this.getdata = function(callbackfunc) {     $http({         method: 'get',         url: '/records/json/',      }).success(function(data){         // data succesfully returned, call our callback         callbackfunc(data);     }).error(function(){         alert("error");     });  } });

and controller looks this

app.controller('rectrl', ['$scope', function($scope, dataservice){     dataservice.getdata(function(dataresponse) {       $scope.fields = dataresponse;     });    ....

but error typeerror: cannot read property 'getdata' of undefined. dont know doing wrong. appreciate help.

you not injecting service (dataservice) controller:

app.controller('rectrl',     ['$scope', 'dataservice', function($scope, dataservice){     dataservice.getdata(function(dataresponse) {       $scope.fields = dataresponse;     });    ....

note string 'dataservice' after '$scope' while defining controller rectrl.

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
