The community has had some issues with links lately. The & # 13 entity gets added sometimes. Mostly on adding a hard line break i've noticed.

Here's the link again:

Hi,

The logic is great in your code.

Made few modifications to your code and it works fine now. Corrected one: 

https://w.trhou.se/9q17t5pvsa

Below were the changes done.

  • the function was called as question.answer. we can access the values of this function by calling 'q1.answer & q2.answer' Moved the function as quiz.answer to access the values of rightanswer and wronganswer.

  • Initially the answer value was not passed to be validated as correct/wrong answer. So modified the function button.onclick() to pass the answer which was selected by the user to be validated.

  • quiz.answer loop checks the answer and increments the score value. (Commente the quiz.checkAnswer and moved the logic to quiz.answer)

  • Included console.log to know the flow of changes.

Please let me know if you have any doubts.

Thanks, Aishu

Aaron;

It appears as though the issue resides in your checkAnswer function:

Quiz.prototype.checkAnswer=function(){
  if(this.questions.answer===true){
    this.score++;
    this.questionIndex++;
  }else{
   this.questionIndex++; 
  }

}

In my solution I had to pass in a parameter into the function to be able to compare the answer with the current question.. Something along the lines of:

Quiz.prototype.checkAnswer = function(answer) {
    // do some comparison
};

As an aside, you can reduce you code a bit as follows:

Quiz.prototype.checkAnswer=function(){
  if(this.questions.answer===true){
    this.score++;
  }
   this.questionIndex++;  
};

Post back if you are still stuck.

Happy coding,
Ken
