my question need angular js send json file , json should saved database using rest services.. idea achieve using angular fr client..

witrh angular, easiest way use $resource. in case, that:

var app = (...)  app.factory('driverpropfacaderest', function($resource) {     return $resource('http://(...)/driverprops/:id', {id:'@id'}); });  app.controller('driverpropcontroller', function($scope, driverpropfacaderest) {     var inputdata = { 'driverid': 'value', (...) };     driverpropfacaderest.save(inputdata, function(data) {         console.log(data);         (...)     }); });

see link in angular reference documentation more details: https://docs.angularjs.org/api/ngresource/service/$resource.

you use low level api $http, described below:

app.controller('driverpropcontroller', function($scope, $http) {     var inputdata = { 'driverid': 'value', (...) };     $http.post('http://(...)/driverprops', inputdata)          .success(function(data, status, headers, config) {               // callback called asynchronously               // when response available          })          .error(function(data, status, headers, config) {               // called asynchronously if error occurs               // or server returns response error status.          }); });

see link in angular reference documentation more details: https://docs.angularjs.org/api/ng/service/$http#post.

hope helps you, thierry

java - UML - How would you draw a try catch in a sequence diagram? -

Image
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...
