试图用可变问题进行测验，无法让按钮给出不同的真/假值

Question

This is my first question here. I'm pretty new to this and I'm not sure what's wrong.

I'm trying to get my code to give a different value depending on the question that's being asked. It keeps giving results as if every time I pressed the correct answer.

function nextQuestionA()
{
 if (numPA == 1)
 {
   numPA = 2;
   if(document.getElementsByName("choiceB"))
   {
     contador = contador + 1; 
     console.log(contador,numPA); 
   }
   else {null}
 }
 if (numPA == 2)
 {
   numPA = 3;
   if (document.getElementById("choiceC").onclick)
   {
     contador = contador + 1;
     console.log("contador");
   }
   else {null}
 }
}

Here's the HTML

<div id="animales">
  <h3>Trivia Animales</h3>
 <link rel= "stylesheet" href="style.css"> 
 <p4 id="a question number"></p4>
  <p5 id="questions animals"></p5>
  <button id="choiceA" value="a" onclick="nextQuestionA()"></button>
  <button id="choiceB" value="b" onclick="nextQuestionA()"></button>
  <button id="choiceC" value="c" onclick="nextQuestionA()"></button>
</div>

I also have the full code in Repl.it here: https://repl.it/@ClaviHaze/LightcoralCalculatingFields

Thank you in advance

Revised Code jsfiddle: https://jsfiddle.net/zeamq4y9/

This is as far as I can take you unless you provide more information about what you want your code to do in terms of functionality. Do you want to go to question #2 after the user selects an answer? Or do you want the user to stay on that same question? I didn't see anywhere in the code where you are doing anything besides printing items to the console after a button is clicked. I changed some of your JavaScript to JQuery to make the code more legible and I also fixed some of your syntax errors. Please review the jsfiddle and make improvements within your if and else statements. Some of your logic for your code is confusing such as there are two if statements back to back. You would need to accompany your first if with an else or and else if followed by an else .Do so, so that myself and others that are trying to help can understand the problem and better provide quality assistance with your problem.
