jQuery延迟() - 如何停止它?

发布于 2024-12-12 04:20:52 字数 1487 浏览 0 评论 0原文

我已经尝试过 stop(true,true)、stop(true) 和clearQueue();但这行不通。

我在快速更换幻灯片时遇到问题,我已经有一些必须重置所有内容的功能,但它不起作用。

function reset(){
   $('div').clearQueue();
   $('#img').html('').css({'left':0,'right':0,'opacity':1,'z-index':1});
   $('#img2').html('').css({'left':0,'right':0,'opacity':1,'z-index':1});
   $('#place').html('');$('#place').html('<div id="img"></div><div id="img2"></div>');
}

但我认为这不会停止(或删除)动画上的delay() 函数。所以我不知道是否不必使用 setTimeout 函数。

这是一段动画脚本:

reset();
actual_slide=2;
  $('#img').html('<img src="'+image[4]+'" alt="Obrázek">').css({'opacity':0,'z-index':2}).delay(time_delay/5).fadeTo(time_fast,1).delay(time_delay*2).fadeTo(time_fast,0);
  $('#img2').html('<img src="'+image[3]+'" alt="Obrázek">').css({'opacity':'0','top':0}).fadeTo(time_fast,1).animate({'top':'-495'},time_delay*3,function(){
    if(actual_slide==2){$('#img2').css({'top':0}).fadeTo(time_fast*2,0).html('');}else{reset();}
    if(actual_slide==2){$('#img').html('<img src="'+image[3]+'" id="1" alt="Obrázek">').fadeTo(time_fast*2,'1').css({'left':-300,'top':-700}).animate({'left':-900,'top':-700},time_delay*2);}else{reset();}
    if(actual_slide==2){$('#1').css({'width':1365,'height':1200}).animate({'width':1665,'height':1400},time_delay*2);}else{reset();}
  });                          

在重复该功能之前,actual_slide必须保护它,但这也不起作用..问题是当我快速更改幻灯片时,因为重置不会停止一切,并且它开始做一些事情我不想加入(比如将图片更改为其他图片)。

I already tried stop(true,true), stop(true) and clearQueue(); but this doesn't work.

I have problem with fast changing slides, i already have some function what have to reset everything, but it doesn't work.

function reset(){
   $('div').clearQueue();
   $('#img').html('').css({'left':0,'right':0,'opacity':1,'z-index':1});
   $('#img2').html('').css({'left':0,'right':0,'opacity':1,'z-index':1});
   $('#place').html('');$('#place').html('<div id="img"></div><div id="img2"></div>');
}

But i thing this doesn't stop (or delete) delay() function on animations. So I don't know if i don't have to use setTimeout function.

Here is piece of animation script:

reset();
actual_slide=2;
  $('#img').html('<img src="'+image[4]+'" alt="Obrázek">').css({'opacity':0,'z-index':2}).delay(time_delay/5).fadeTo(time_fast,1).delay(time_delay*2).fadeTo(time_fast,0);
  $('#img2').html('<img src="'+image[3]+'" alt="Obrázek">').css({'opacity':'0','top':0}).fadeTo(time_fast,1).animate({'top':'-495'},time_delay*3,function(){
    if(actual_slide==2){$('#img2').css({'top':0}).fadeTo(time_fast*2,0).html('');}else{reset();}
    if(actual_slide==2){$('#img').html('<img src="'+image[3]+'" id="1" alt="Obrázek">').fadeTo(time_fast*2,'1').css({'left':-300,'top':-700}).animate({'left':-900,'top':-700},time_delay*2);}else{reset();}
    if(actual_slide==2){$('#1').css({'width':1365,'height':1200}).animate({'width':1665,'height':1400},time_delay*2);}else{reset();}
  });                          

That actual_slide have to protect it before repeating that function, but that doesn't work too.. Problem is when i fast changing slides, because that reset doesn't stop everything, and it start doing things what i don't want to have in (like change picture to other and other).

您可以通过 .dequeue() 函数打破 .delay()

这里是示例

//this is only for make sure that we skip 'delay', not other function
var inDelay = false;

function start()
{
    $('.gfx').animate
    ({
        width: 100
    }, function(){inDelay = true}).delay(3000).animate
    ({
        width: 0
    }, function(){inDelay = false})
}

function breakTheDelay()
{
    if(inDelay)
    {
        $('.gfx').dequeue();
    }
}

http ://jsfiddle.net/wasikuss/5288z/

//编辑:更复杂的示例提供了日志记录时间戳和清理(没有清理,多次点击 Start 是不可预测的)来证明它适用

http://jsfiddle.net/q0058whc/

或以下版本

//this is only for make sure that we skip 'delay', not other function
var inDelay = false;
var ltime = 0;

// console log will aways show 'end' values: 2000, 1000 an 400
// values may be different due to time wasted on calling functions
// sometimes delay is shorten by 0-200ms, it can be caused by js engine probably  

function start()
{
    cleanup();
    ltime = (1*new Date());
    $('.gfx').queue('fx', function(next)
    {
      logtime( 'animate1_start' );
    	$('.gfx').animate
      ({
          width: 100
      }, 2000, function(){logtime('animate1_end');inDelay = true;})
      next();
    })
    .queue('fx', function(next)
    {
    	logtime('delay_start');
    	next()
    })
    .delay(1000)
    .queue('fx', function(next)
    {
    	logtime('delay_end');
    	next()
    })
    .queue('fx', function(next)
    {
    	logtime('animate0_start');
    	$('.gfx').animate
      ({
          width: 0
      }, function(){logtime('animate0_end');inDelay = false;})
      next()
    });
}

function cleanup()
{
		// remove current queue
    $('.gfx').clearQueue()
    // first animate runned interval. stop it 
    .stop()
    // reset width of element
    .css('width',0)
}

function logtime( name )
{
	var ntime = (1*new Date());
	console.log( name + ': ' + ( ntime - ltime ) );
  ltime = ntime;
}

function breakTheDelay()
{
    if(inDelay)
    {
        $('.gfx').dequeue();
    }
}

//
// version without 'inDelay' check only if you know what are you doing
// http://jsfiddle.net/wasikuss/hkw9H/
//
.gfx
{
    background: red;
    width: 0;
    height: 10px
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button onclick="start()">Start</button>
<button onclick="breakTheDelay()">Can't wait!</button>
<div class="gfx"></div>

You can break .delay() by .dequeue() function

here is example

//this is only for make sure that we skip 'delay', not other function
var inDelay = false;

function start()
{
    $('.gfx').animate
    ({
        width: 100
    }, function(){inDelay = true}).delay(3000).animate
    ({
        width: 0
    }, function(){inDelay = false})
}

function breakTheDelay()
{
    if(inDelay)
    {
        $('.gfx').dequeue();
    }
}

http://jsfiddle.net/wasikuss/5288z/

//edit: more complex example provided with logging timestamps and cleanup ( without cleanup, multiple clicks on Start is unpredictable ) to prove that it works

http://jsfiddle.net/q0058whc/

or below

//this is only for make sure that we skip 'delay', not other function
var inDelay = false;
var ltime = 0;

// console log will aways show 'end' values: 2000, 1000 an 400
// values may be different due to time wasted on calling functions
// sometimes delay is shorten by 0-200ms, it can be caused by js engine probably  

function start()
{
    cleanup();
    ltime = (1*new Date());
    $('.gfx').queue('fx', function(next)
    {
      logtime( 'animate1_start' );
    	$('.gfx').animate
      ({
          width: 100
      }, 2000, function(){logtime('animate1_end');inDelay = true;})
      next();
    })
    .queue('fx', function(next)
    {
    	logtime('delay_start');
    	next()
    })
    .delay(1000)
    .queue('fx', function(next)
    {
    	logtime('delay_end');
    	next()
    })
    .queue('fx', function(next)
    {
    	logtime('animate0_start');
    	$('.gfx').animate
      ({
          width: 0
      }, function(){logtime('animate0_end');inDelay = false;})
      next()
    });
}

function cleanup()
{
		// remove current queue
    $('.gfx').clearQueue()
    // first animate runned interval. stop it 
    .stop()
    // reset width of element
    .css('width',0)
}

function logtime( name )
{
	var ntime = (1*new Date());
	console.log( name + ': ' + ( ntime - ltime ) );
  ltime = ntime;
}

function breakTheDelay()
{
    if(inDelay)
    {
        $('.gfx').dequeue();
    }
}

//
// version without 'inDelay' check only if you know what are you doing

从 jQuery 延迟 页面:

.delay() 方法最适合在排队的 jQuery 之间进行延迟
影响。因为它是有限的——例如,它没有提供一种方法
取消延迟——.delay() 不能替代 JavaScript 的原生
setTimeout 函数,这可能更适合某些用途
案例。

看一下 doTimeout 插件;这可能就是您正在寻找的。

我希望这有帮助!

From the jQuery delay page:

The .delay() method is best for delaying between queued jQuery
effects. Because it is limited—it doesn't, for example, offer a way to
cancel the delay—.delay() is not a replacement for JavaScript's native
setTimeout function, which may be more appropriate for certain use
cases.

Take a look at the doTimeout plugin; it may be what you are looking for.

I hope this helps!

通过 这篇文章 有一个非常简单的方法,那就是使用 .animate 代替 .delay

Via this post there's a very simple approach, which is to use .animate in place of .delay

我希望用户一遍又一遍地快速重新启动动画链,有时是在动画中间。因此,我没有使用 delay(),而是将动画设置为虚假的 css 属性 {"null":1}。这是一个简单的淡入/淡出。似乎对我有用!

//- fade in
$el.stop().animate({"opacity":1}, 200, "easeInSine", function(){
    //- delay for 2000ms
    $el.stop().animate({"null":1}, 2000, function(){
        //- fade out
        $el.stop().animate({"opacity":0}, 1000, "easeInOutSine", function(){
            //- final callback
        });
    });
});

I wanted a user to rapidly restart an animation chain over and over again, sometimes in the middle of the animation. So instead of using delay() I animated to a bogus css propery {"null":1}. Here's a simple fade-in/fade-out. Seems to have worked for me!

//- fade in
$el.stop().animate({"opacity":1}, 200, "easeInSine", function(){
    //- delay for 2000ms
    $el.stop().animate({"null":1}, 2000, function(){
        //- fade out
        $el.stop().animate({"opacity":0}, 1000, "easeInOutSine", function(){
            //- final callback
        });
    });
});
