我正在构建问卷,问题可以有多个答案,我需要建立一个问题和答案的数组,例如:
{
question: 'question',
answer: {id: 1, answers: 'answer 1'},
{id: 2, answer: 'answer 2'}
}
我需要显示用户选择的问题和答案的摘要。
例如:问题:你住在哪些州? 答案:阿拉巴马州,阿拉斯加州,新泽西州,罗德岛州。
结果对象可能是:
{
question: 'Which of these states have you lived in?',
answer: {id: 1, answer: 'Alaska'},
{id: 3, answer: 'Rhode Island'}
}
如果只显示一次问题,我该如何动态添加答案?
我试过了:
var questionAnswerObject = [];
angular.forEach(answersObject, function(value, key){
questionAnswerObject.push({
question: question.question,
answer: value.answer
});
});
但当然它会两次显示问题。
答案 0 :(得分:1)
你遗失的东西非常重要:你需要answers
成为一个数组(或一个对象),包含所有的答案。你不能按照你想要的方式将多个对象分配给一个值 - 它们需要以某种方式包装。
因此,例如,您的答案对象可能会这样:
var answerObject = {
question: 'My Question',
answers: [
{id: 1, answer: 'first answer'},
{id: 2, answer: 'second answer'}
]
}
或者,您可以像answers
一样制作问题ID的地图:
var answerObject = {
question: 'My Question',
answers: {
1: 'first answer',
2: 'second answer'
}
}
要在第一个示例中添加答案,只需执行以下操作:
answerObject.answers.push( {id: 3, answer: 'new answer'} );
要在第二个示例中添加答案,只需执行以下操作:
answerObject.answers[3] = 'new answer';
答案 1 :(得分:0)
我认为你的意思是你的最终目标就像这个问题和一系列答案
var arrayObjQuestions = [{
question: 'question',
answer: [{id: 1, answers: 'answer 1'},
{id: 2, answer: 'answer 2'}]
},...];
所以如果你有循环投掷问题并添加答案如下
arrayObjQuestions[0].answer.push({id:1, answer: "answer 1"});
arrayObjQuestions[0].answer.push({id:2, answer: "answer 2"});
arrayObjQuestions[0].answer.push({id:3, answer: "answer 3"});
答案 2 :(得分:0)
实现这一目标的最佳方法是:
var questionAnswerObject = {};
var answers = [];
answers.push({id:1, answer: 'Alaska'});
answers.push({id:3, answer: 'Rhode Island'});
questionAnswerObject["question"] = 'Which of these states have you lived in?';
questionAnswerObject["answer"] = answers ;
