トリビアゲームが正しくスコアリングされない

Question

私が学んでいるように、私はトリビアゲームの作成を任されています。私は本当に私が正しい道にいると思った。問題は、自分のゲームで「完了」をクリックすると、答えに関係なくです。彼らはすべて正しく戻って来ません。私はこの欠陥がどこにあるのか分かりません。誰かが驚くべきエラーを指摘できるかどうか。

$('#start').on('click', function(){ 
game.start(); 
}) 

$(document).on('click','#end',function(){ 
game.done(); 
})

Answer 1

あなたがそうquestions[i].answers[j]+" '

の間に自分の価値観の比較でそれぞれ正解に余分な「スペース」を追加気づけばあなたのエラーがライン

$("#wrap").append("<input type = 'radio' name = 'question-" +i+"' value = '"+questions[i].answers[j]+" '> "+questions[i].answers[j]) 

でありますその余分なスペースのために正解と選択された値が決して真実ではない
