请帮帮忙，我一直停留了几个小时试图弄明白，我用我的问题，选择和答案一多维阵列和希望按钮的onclick继续到下一个问题，而它检查是否点击的答案是正确的

'onclick按钮并不是真的在做我所希望的事情。你希望它会做什么，它现在没有做？ –

我希望当你点击它时，它会运行函数CheckAnswer（1）的参数内的值，所以我可以将该值与正确的答案，这是我的Quiz [pos] [5]数组，但它不这样做 –

答

qpos + 1

需求，要么是qpos++或qpos = qpos + 1起码

哇，谢谢你这么多，这ACTUALLY固定它我知道有没有任何错误与我如何设置我的按钮噢，谢谢你这个固定的一切对不起，我即时大肆宣传现在因为我卡住了一段时间 –

只是一个专业提示，你可以通过添加控制台记录事物（我确实了解了你的值是否正在改变），或者在浏览器的开发工具中使用了断点。 – maggiekh

正式指出再次感谢 –

答

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


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

修复它与以前的帖子，你的想法一样谢谢 –
