从onclick重新加载数据库中的内容

Question

I want to write a little quiz app. The problem is if I try to get a new question by calling a function with executes a select onclick, no new question appears. It just do nothing.

I tried two different ways: -I tried to select all ten questions with one select, but I couldn't find out how to pass the multi array to javascript -Then I tried to select only one new question every time I answer a question (onclick on an answer).

I'm not quite sure which solution is the better way to do that. I guess there is something wrong with the logic in my program but I really don't know. It would be great if someone could help me out with that. Here is my code:

php

$questions = $db->excSelect("SELECT * FROM question WHERE art = 0 ORDER BY RAND() LIMIT 10");

function getQuestion($questions) {
    return json_encode($questions);
}

javascript

$().ready(function() {
            var questionNumber = 0;
            var question = JSON.parse('<?php echo getQuestion($questions); ?>');

            function showQuestion() {
                $("#question").text(question[questionNumber].question);
                $("#answer-1").text(question[questionNumber].answer_1);
                $("#answer-2").text(question[questionNumber].answer_2);
                $("#answer-3").text(question[questionNumber].answer_3);
                $("#answer-4").text(question[questionNumber].answer_4);
                questionNumber++;
            }
            showQuestion();
            $(".answer").click(function() {
                if (questionNumber != 10) { showQuestion(); }
                else { $("#quiz-site").text("EVALUATION"); }
            });
        });

html

<article id="quiz-site">
    <section id="quiz">

        <section id="question"></section>

        <section class="block1">
            <section id="answer-1" class="answer"></section>
            <section id="answer-2" class="answer"></section>
        </section>

        <section class="block2">
            <section id="answer-3" class="answer"></section>
            <section id="answer-4" class="answer"></section>
        </section>
    </section>  
</article>

I get the first question correctly inserted into the sections, but as soon as I click on an answer it does nothing.
