我是 AngularJS 新手。我使用工厂向 dom 填充了一些问题。我必须验证单选按钮是否已选中。请提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"]}
];
});
最佳答案
您可以结合使用 ng-disabled 和 ng-show 指令来验证和显示错误消息。
