javascript - Bind ng-options value and label to ng-model -

-

i'm using ng-options generate select tag options locations. labels location names, , values location id (in database).

i've bound value (location id) ng-model attribute, i'd bind label (location name) different ng-model attribute. (i need separate id field since posted server expects particular attribute.) what's best way in angular?

my code:

<div ng-app="app"><div ng-controller="edit">   <select ng-model="purchase.pickuplocationid" ng-options="loc.id loc.name loc in purchase.availablelocations"></select>    <!-- model not yet bound: -->   <p>you have selected {{ purchase.pickuplocationname }}</p>  </div></div> 
var app = angular.module('app', []);  app.controller('edit', ['$scope', function($scope) {     $scope.purchase = {         pickuplocationid: 30,         availablelocations: [             {id: 20, name: "charleston, sc"},             {id: 30, name: "atlanta, ga"},             {id: 40, name: "richmond, va"},         ]     }; }]);

you can change following , bind entire object. you'll still have access id later on whatever wish it

<select ng-model="selected" ng-options="loc loc.name loc in purchase.availablelocations"></select> 
<p>you have selected {{ selected.name }}</p> <p>you havd id too! {{ selected.id }}</p>

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

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...
