我想制作“旋转轮”类型的游戏,因为用户可以选择三种可能的结果,然后,在他们旋转轮子之后,如果出现所选择的三个中的任何一个,那么他/她就是赢家.
在下面的演示中,您可以看到,微调器停止后,结果不是正确的值。微调器本身停止后,它会继续并更改值——在最后一个之前,它始终是灯泡。 (请全屏查看我指的是什么。)
我该如何解决这个问题?
//set default degree (360*5)
var degree = 1800;
//number of clicks = 0
var clicks = 0;
$(document).ready(function(){
/*WHEEL SPIN FUNCTION*/
$('#spin').click(function(){
//add 1 every click
clicks ++;
/*multiply the degree by number of clicks
generate random number between 1 - 360,
then add to the new degree*/
var newDegree = degree*clicks;
var extraDegree = Math.floor(Math.random() * (360 - 1 + 1)) + 1;
totalDegree = newDegree+extraDegree;
/*let's make the spin btn to tilt every
time the edge of the section hits
the indicator*/
$('#wheel .sec').each(function(){
var t = $(this);
var noY = 0;
var c = 0;
var n = 700;
var interval = setInterval(function () {
c++;
if (c === n) {
clearInterval(interval);
}
var aoY = t.offset().top;
$("#txt").html(t.html());
console.log(aoY);
/*23.7 is the minumum offset number that

}, 10);

最佳答案
The setInterval() method will continue calling the function until clearInterval() is called, or the window is closed.
setInterval 返回 clearInterval 所需的 ID。
清除间隔计时器并在转换后显示结果(6100 毫秒)。
var degree = 1800;
var clicks = 0;
//Clear interval timer if id saved in attributes:
function clear_interval(t) {
var interval = parseInt(t.data('interval'));
if(interval > 0) {
clearInterval(interval);
t.data('interval', '');
}
}
$(document).ready(function(){
$('#spin').click(function(){
clicks ++;
var newDegree = degree*clicks;
var extraDegree = Math.floor(Math.random() * (360 - 1 + 1)) + 1;
totalDegree = newDegree+extraDegree;
//Calculate result index:
var win_num = 6 - Math.floor((totalDegree % 360 + 30) / 60);
$('#wheel .sec').each(function(){
var t = $(this);
clear_interval(t);
//Save timer ID in data-interval attribute:
t.data('interval', setInterval(function () {
var aoY = t.offset().top;
$("#txt").html(t.html());
if(aoY < 23.89){
$('#spin').addClass('spin');
setTimeout(function () {
$('#spin').removeClass('spin');
}, 100);
}
}, 10));
$('#inner-wheel').css({
'transform' : 'rotate(' + totalDegree + 'deg)'
});
});
//Stop updates and show result when transition already ended:
setTimeout(function () {
$('#wheel .sec').each(function(){
clear_interval($(this));
});
$("#txt").html($('#wheel div.sec:nth-child('+win_num+')').html());
}, 6100);
});
});
