javascript - Angular div not changing text when updating $scope -


i'm have button change underlying $scope , can show changes text in mapped/bound div doesn't change

to specify desired result when click button text button should change text of <div id="text"> how ever doesn't i'm not sure i'm doing incorrectly

var myapp = angular.module('myapp', []);  myapp.controller('myctrl', function($scope){  	$scope.data =    	{"person":       	{"id": 3,        "text": "this text value"        }  		};        });    settimeout(function(){  var elem = document.getelementbyid('ex');  elem.addeventlistener('click',  function(){  	$scope = angular.element(document.getelementbyid('text')).scope();    $scope.data.person.text = "this new text";  },false);    elem = document.getelementbyid('log');  elem.addeventlistener('click', function(){  console.log(angular.element(document.getelementbyid('text')).scope().data.person.text);  },false)    //alert('load');  },500);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>  <div ng-app="myapp" ng-controller="myctrl">    <div id="id" ng-model="data.person.id">{{data.person.id}}</div>    <div id="text" ng-model="data.person.text">{{data.person.text}}</div>  </div>    <button id="ex">  button  </button>    <button id="log">  log  </button>

since using settimeout function need manually start $digest cycle. use $scope.$apply() after text change. start cycle , bind values view 

var myapp = angular.module('myapp', []);  myapp.controller('myctrl', function($scope){  	$scope.data =    	{"person":       	{"id": 3,        "text": "this text value"        }  		};        });    settimeout(function(){  var elem = document.getelementbyid('ex');  elem.addeventlistener('click',  function(){  	$scope = angular.element(document.getelementbyid('text')).scope();    $scope.data.person.text = "this new text";    $scope.$apply()  },false);    elem = document.getelementbyid('log');  elem.addeventlistener('click', function(){  console.log(angular.element(document.getelementbyid('text')).scope().data.person.text);  },false)    //alert('load');  },500);
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>  <div ng-app="myapp" ng-controller="myctrl">    <div id="id" ng-model="data.person.id">{{data.person.id}}</div>    <div id="text" ng-model="data.person.text">{{data.person.text}}</div>  </div>    <button id="ex">  button  </button>    <button id="log">  log  </button>

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
