我的网页中有以下几行代码 - demo/example。
HTML:
<button class="wrong-answer" onclick="showResult(this)">42</button>
<button class="right-answer" onclick="showResult(this)">43</button>
<p id="answer" class="answer-display-hidden">answer</p>
<div class="incorrect">
<span>Incorrect:</span>
<p>0</p>
</div>
<div class="correct">
<span>Correct:</span>
<p>0</p>
</div>
CSS:
.answer-display-visible {
visibility: visible;
opacity: 1;
transition: opacity 1s linear;
}
.answer-display-hidden {
visibility: hidden;
opacity: 0;
transition: visibility 0s 1s, opacity 1s linear;
}
.incorrect, .correct {float: left; padding-right: 20px}
JS:
var incorrectCalls = 0;
var correctCalls = 0;
function showResult(b) {
var res = document.getElementById('answer');
if (b.classList.contains('right-answer')) {
res.innerHTML = '<span class="right">right</span>';
correctCalls++;
var cor = $('.correct > p:first');
cor[0].innerHTML = correctCalls;
}
else {
res.innerHTML = '<span class="wrong">wrong</span>';
incorrectCalls++;
var incor = $('.incorrect > p:first');
incor[0].innerHTML = incorrectCalls;
}
res.classList.remove("answer-display-hidden");
res.classList.add("answer-display-visible");
setTimeout(function() {
res.classList.add("answer-display-hidden");
}, 2000);
}
如何在文本淡入和等待效果期间取消激活right-answer
计数器,然后重新激活?这样用户就无法操作计数器(在显示文本之前快速单击按钮)。

单击按钮时可以使用setTimeout功能。
代码块:
function showResult(b) {
.
.
.
$(".right-answer").prop("disabled", true);
$(".wrong-answer").prop("disabled", true);
setTimeout(function() {
$(".right-answer").prop("disabled", false);
$(".wrong-answer").prop("disabled", false);
}, 2600);
}

这是我的解决方案
删除了CSS代码,以下是jQuery代码。
$(document).ready(function(){
$(".wrong-answer").click(function(){
$(".right-answer").attr("disabled","disabled");
$("#answer").text("WRONG").fadeIn(5000,function(){
$(this).fadeOut(5000,function(){
$(".right-answer").removeAttr("disabled");
});
})
});
});
