javascript - Angular array and ng-repeat for ratio group -


i want make questionnaire can fill directly in app's variables, due don't have database in little project. questionaire made 20 questions , using radio buttons selecting answer. @ end end of questionaire need show selected answers, did scope object testresult

initially, thinking fill 20 questions , radio variables manually, saw ng-repeat angular function can helpful, , know if can use in case.

i may storing initial values of each radio group inside , array, , print them in view using ng-repeat. don't have clue start.

the next piece of code related project.

view

<div class="form-group">     <div class="radio">         <label><input type="radio" name="qs01" ng-model="testresult.qs01" value="1">             question one.         </label>     </div>     <div class="radio">         <label><input type="radio" name="qs01" ng-model="testresult.qs01" value="2">             question two.         </label>     </div>     <div class="radio">         <label><input type="radio" name="qs01" ng-model="testresult.qs01" value="3">             question three.         </label>     </div>     <div class="radio">         <label><input type="radio" name="qs01" ng-model="testresult.qs01" value="4">             question four.         </label>     </div>     <div class="radio">         <label><input type="radio" name="qs01" ng-model="testresult.qs01" value="5">             question five.         </label>     </div> </div>

app

// test result object $scope.testresult = {};

what need repeat is:

<div class="radio">     <label><input type="radio" name="qs01" ng-model="testresult.qs01" value="question variable">         question variable     </label> </div>

you putting different labels on each radio. each radio option value of same question.

you need include radio options array use ng-repeat. do:

$scope.qs01options = ['blue', 'red', 'yellow'];

<div class="form-group">     <div class="radio">         <label>question one.</label>         <input ng-repeat="opt in qs01options" type="radio" name="qs01" ng-model="testresult.qs01" value="{{opt}}">     </div> </div>

this repeats options 1 question. name stays same because that's how radio inputs same field work in form.

if want have multiple questions, each multiple options, need use array of arrays; each object hold array of options question.

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...
