Question

我正在创建一个带按钮的在线测验，我的问题是onclick按钮并没有真正做我希望的事情，我是javascript的初学者所以我希望人们可以给我解决方案或其他建议让它工作;

这是我的代码

<html>

<script>

var qpos = 0;
var correctans=0;
var answer=0;


var Quiz = [
    ["What team was the first TI Champion?", "Invictus Gaming", "Team Liquid", "Natus Vincere", "Orange E-Sports", 'C'],
    ["Who was the captain of the First TI Champion Team?", "Puppey", "Artstyle", "Kuroky", "xiao8", 'B'],
    ["Where does Natus Vincere Operate?", "USA", "Moscow", "Philippines", "Ukraine", 'D'],
    ["Who played Midlane for Natus Vincere?", "Miracle", "Suma1l", "Dendi", "Maybe", 'C'],
    ["How many TI grandfinals did Team Natus Vincere played in?", "3", "2", "1", "4", '1'],
    ["Who replaced LightofHeaven after leaving Natus Vincere?", "General", "Sonneiko", "rodger", "Funn1k", 'D'],
    ["Who defeated Na'Vi in the TI3 Grand Finals?", "Team Liquid", "Cloud 8", "Evil Geniuses", "Team Alliance", 'D'],
    ["Who is the current captain of Team Na'Vi?", "Pajkatt", "Cr1t", "Sonneiko", "Fly", 'C'],
    ["Who is the owner of Na'Vi?", "Gaben", "CyborgMatt", "ODpixel", "zer0gravity", 'D'],
    ["When was Team Natus Vincere Founded?", "July 1996", "December 2009", "November 2012", "March 2017", 'B']
];

function startquiz(){   
    getQuestions(); 
};  

function getQuestions() {

        document.getElementById("qholder").innerHTML = Quiz[qpos][0];
        document.getElementById("choice1").innerHTML = Quiz[qpos][1];
        document.getElementById("choice2").innerHTML = Quiz[qpos][2];
        document.getElementById("choice3").innerHTML = Quiz[qpos][3];
        document.getElementById("choice4").innerHTML = Quiz[qpos][4];

        };  


function CheckAnswer (answer){
    if(Quiz[qpos][5] == answer) {
      correctans + 1; 
    };
  getnextQuestion();    
};


function getnextQuestion() {
    qpos + 1;
    getQuestions();
};

startquiz();

</script>
</body>
</html>

请帮助，我已经被困了几个小时试图解决它，我使用多维数组来解决我的问题，选择和答案，并希望按钮onclick继续下一个问题，同时检查是否点击了答案是对的

Answer 1

qpos + 1

至少需要qpos++或qpos = qpos + 1

Answer 2

const char *test(const char *const *foo)
{
    return foo[0];
}

int main(void)
{
    const char *arr[10];
    arr[0] = "Foobar";

    const char *x = test(arr);
    return (int) *x;
}

Onclick to a function不起作用
