我知道这个问题可以通过多种方式回答,但我需要有人为我做到这一点。我希望我的动画做它的事情,然后弹出一个随机数?现在,我一键有2个功能(我需要)。我是新手,一个简单的公式将很棒!任何人都可以提供帮助,如果可以的话,这将不胜感激!谢谢你!这是所有代码!
startbtn = function() {
$('.wheel').addClass('animated-wheel');
setTimeout(setRandom('random') {}, 6000);
}
function getRandom() {
var values = [1, 15, 30, 45];
return values[Math.floor(Math.random() * values.length)];
}
function setRandom(id) {
document.getElementById(id).innerHTML = getRandom();
}
function refresh() {
location.reload();
};
.number {
text-align: center;
color: white;
font-size: 78px;
}
.wheel {
width: 200px;
height: 100px;

.animated-wheel {
-webkit-animation: myfirst4s 2;

您的 setTimeout()
中有一个语法错误:
startbtn = function() {
$('.wheel').addClass('animated-wheel');
setTimeout(function() {
// Remove animation class
setRandom('random');
$('.wheel').removeClass('animated-wheel');
}, 6750);
}
function getRandom() {
var values = [1, 15, 30, 45];
return values[Math.floor(Math.random() * values.length)];
}
function setRandom(id) {
document.getElementById(id).innerText = getRandom();
}
function refresh() {
location.reload();
};

希望这会有所帮助,
有更多优雅的方式,但这里是对您的错误的纠正:
setTimeout(function(){
setRandom('random')
}, 6000);
