我如何做到这一点，以便在下一行或问题 2、3、4 等时自动滚动到该行或问题，这样用户就不必手动滚动以查看下一个问题，因为它会变得很麻烦，并且会减少回答问题的时间。我试图将自动滚动添加到 div，但图像消失了。

最佳答案
用工作代码更新了你的 fiddle :
$("html,body").animate({scrollTop :questions.eq(i).offset().top})
这里是完整的函数:
var showQuestions = function (index) {
for (var i = 0; i < questions.length; i++) {
if (i < index) {
questions.eq(i).css("display", "block");
} else {
questions.eq(i).css("display", "none");
}
}
if (index > 1) {
// only scroll to the questions after the first one is clicked
$('html, body').animate({
scrollTop : $(questions.eq(index - 1)).offset().top
});
}
}
