我正在做一个简单的倒计时,进度条在倒数的同时增加并显示一个随机数,并在10秒后再次重置。
第一次尝试有效,但第二次尝试不再同步。如果我把这行this.stop()
放回去,它可以被同步。我的问题是还会有另一个问题。它将生成额外的数组。
希望你能帮助我。
谢谢。
let time = 10;
let progress = 0; let counter = 0
var clock = $('.my-clock').FlipClock(time, {
countdown: true,
count: 1,
callbacks: {
stop: function() {
setTimeout(function(){
clock.setTime(time); // proceeding time
clock.start();
},10000);
for (let i = 0; i < 5; i++) {
var arrResult = [];
setTimeout(function(){
var r = Math.floor(Math.random() * 11) + 1;
arrResult.push(r);
setTimeout(function(){
$('.numResult div:nth-child('+ (i+1) +')').html(arrResult[i]);
},200);
if(arrResult.length === 5){
$('.results ul').append('<li>'+ arrResult +'</li>');
}
},500 * i);
}
},
interval: function() {
counter && (progress+=100/time);
counter ++;
$('.progressBar .progress').width(progress+ '%');
if(progress >= 100) {
progress = 0; counter = 0;
// this.stop()
}
}
}

答案 0 :(得分:1)
我也有一段时间对此感到迷惑。
时间问题通常是微不足道的。
问题是... interval
回调在数字翻转动画的开始处触发 (延迟时间为1秒)。
因此,肉眼可见,在第一次回调触发时显示的数字是10 ...并且刚开始翻转到09。由于您还有10秒的时间,因此您现在不想升级进度条。向左(或说9.99秒)。这就是为什么您进行counter && (progress+=100/time);
相当于if(counter){progress+=100/time;}
的原因。
这会在progress
上创建一个“迭代跳过” ...并且每次counter
等于0时,它就会偏移1。请参见此处:
console.clear();
let time = 10;
let progress = 0; let counter = 0
var clock = $('.my-clock').FlipClock(time, {
countdown: true,
count: 1,
callbacks: {
stop: function() {
setTimeout(function(){
clock.setTime(time); // proceeding time
clock.start();
},10000);
for (let i = 0; i < 5; i++) {
var arrResult = [];
setTimeout(function(){
var r = Math.floor(Math.random() * 11) + 1;
arrResult.push(r);
setTimeout(function(){
$('.numResult div:nth-child('+ (i+1) +')').html(arrResult[i]);
},200);
if(arrResult.length === 5){
$('.results ul').append('<li>'+ arrResult +'</li>');
}
},500 * i);
}
},
interval: function() {
// Check for that progress being consoled to zero TWICE on load.
console.log("progress: "+progress);
counter && (progress+=100/time);
counter ++;
$('.progressBar .progress').width(progress+ '%');
if(progress == 100) {
progress = 0; counter = 0;
}
}
}
});
.my-clock {
text-align:center;
width:auto;
display: inline-block;
}
.center {
text-align:center;
}
.progressBar{
margin: 0 auto;
width: 400px;
height: 6px;
border-radius: 3px;
background-color: #222;
}
.progress{
background-color: green;
height: 100%;
width: 100%;
}
.numResult div{
display: inline-block;
}
.results{
width: 50px;
position: absolute;
left: 0;
right: 0;
margin: 0 auto;
}
.results ul{
padding: 0;

因此,跳过了非常第一迭代(页面加载),您的回调“定时”现在与翻转动画的结尾对齐(人眼)。没错,您不必再次“跳过”迭代。
因此,当progress
等于100时,将progress
重置为0 ...但是将counter
重置为1!这样您就不会再跳过了。看到这里:
console.clear();
let time = 10;
let progress = 0; let counter = 0
var clock = $('.my-clock').FlipClock(time, {
countdown: true,
count: 1,
callbacks: {
stop: function() {
setTimeout(function(){
clock.setTime(time); // proceeding time
clock.start();
},10000);
for (let i = 0; i < 5; i++) {
var arrResult = [];
setTimeout(function(){
var r = Math.floor(Math.random() * 11) + 1;
arrResult.push(r);
setTimeout(function(){
$('.numResult div:nth-child('+ (i+1) +')').html(arrResult[i]);
},200);
if(arrResult.length === 5){
$('.results ul').append('<li>'+ arrResult +'</li>');
}
},500 * i);
}
},
interval: function() {
// Check for that progress being consoled to zero TWICE on load.
console.log("progress: "+progress);
counter && (progress+=100/time);
counter ++;
$('.progressBar .progress').width(progress+ '%');
if(progress == 100) {
progress = 0; counter = 1;
}
}
}
});
.my-clock {
text-align:center;
width:auto;
display: inline-block;
}
.center {
text-align:center;
}
.progressBar{
margin: 0 auto;
width: 400px;

.progress{
background-color: green;
height: 100%;
width: 100%;
}
.numResult div{
display: inline-block;

.results{

所以现在,进度栏和活动时钟保持对齐。好。但是您当然会注意到,进度栏永远不会回到0。并且,当翻转开始!
时,进度栏会更新。那是因为进度条更新没有像Flipclock这样的动画延迟。那么,为什么不使用animate()
的宽度而不使用.width()
呢?
$('.progressBar .progress').animate({"width":progress+ '%'},1000,"linear");
查看此处:
console.clear();
let time = 10;
let progress = 0; let counter = 0
var clock = $('.my-clock').FlipClock(time, {
countdown: true,
count: 1,
callbacks: {
stop: function() {
setTimeout(function(){
clock.setTime(time); // proceeding time
clock.start();
},10000);
for (let i = 0; i < 5; i++) {
var arrResult = [];
setTimeout(function(){
var r = Math.floor(Math.random() * 11) + 1;
arrResult.push(r);
setTimeout(function(){
$('.numResult div:nth-child('+ (i+1) +')').html(arrResult[i]);
},200);
if(arrResult.length === 5){
$('.results ul').append('<li>'+ arrResult +'</li>');
}
},500 * i);
}
},
interval: function() {
if(progress == 0){
$('.progressBar .progress').width("0%");
}
counter && (progress+=100/time);
counter ++;
$('.progressBar .progress').animate({"width":progress+ '%'},1000,"linear");
if(progress == 100) {
progress = 0; counter = 1;
}
}
}
});

当.width()
为0时,progress
仍然有用,因为您不想看到动画从100到10 ...但是从0到10。这就是添加条件的原因。 / p>
if(progress == 0){
$('.progressBar .progress').width("0%");
}
最后一个代码段将是您的解决方案...;)
