我是AngularJS新手。我用工厂填充了一些问题。我必须验证是否选中了单选按钮。请给出改进此代码的建议
index . html
<body ng-app="quiz">
<div id="container" ng-controller="QuizController">
<button ng-click="submitfun()">submit</button>
</div>
</body>
app.js
angular.module('quiz', ['quiz.service','quiz.directive']);
var QuizController = function($scope, questionFactory) {
$scope.questions_and_answers = questionFactory;
$scope.checkList=[];
$scope.submitfun= function(message){
alert('hi');
}
};
factory.js
angular.module('quiz.service', [])
.factory('questionFactory', function() {
return [
{ question: "Which of these is England's official slogan for the World Cup?", answerChoices: [ "Impossible is not an English word", "One nation, one team, one dream!", "Real men wear red and white","The dream of one team, the heartbeat of millions!!" ] },
{ question:"Who was Roy Keane talking this week about when he said: "Not everybody wants to wander around the pitch waving and crying?" ", answerChoices:["David Moyes","John Terry","Luis Suárez","Rio Ferdinand"]}
];
});
你可以组合使用ng-disabled和ng-show指令来验证和显示错误信息。
