添加幻灯片更改之前的延迟

标签: javascript jquery swiper

我正在使用Swiper Slider。在单击“下一个/上一个”按钮后,是否可以在幻灯片更改之前添加延迟?例如:我单击下一步按钮,等待1秒钟,然后切换到下一张幻灯片。我需要这样做,因为我已经使用CSS制作了自己的动画,并且需要使用aprox。 1秒才能完全完成。

希望你们能帮我这个忙。

代码如下:

var swiper = new Swiper('.swiper-container', {
      navigation: {
        nextEl: '.swiper-button-next',
        prevEl: '.swiper-button-prev',
      },
    });
.swiper-container {
      width: 100%;
      height: 100%;
    }
    .swiper-slide {
      text-align: center;
      font-size: 18px;
      background: #fff;
      /* Center slide text vertically */
      display: -webkit-box;
      display: -ms-flexbox;
      display: -webkit-flex;
      display: flex;
      -webkit-box-pack: center;
      -ms-flex-pack: center;
      -webkit-justify-content: center;
      justify-content: center;
      -webkit-box-align: center;
      -ms-flex-align: center;
      -webkit-align-items: center;
      align-items: center;
    }

        <div class="swiper-slide">Slide 2</div>
        <div class="swiper-slide">Slide 3</div>

这可以按照您的要求进行。

通过删除导航定义,我们可以为下一个和上一个按钮编写自己的操作。

我用setTimeout等待指定的时间,然后从您的库中启动了内置的next / previous函数。

我还添加了一些CSS,以便在此期间按钮显示为禁用状态,以便用户理解应该再次单击。


演示

// Initialise swiper
var swiper = new Swiper('.swiper-container');

// Define delay (in milliseconds)
swiperDelay = 2000;

// Add event to previous button
$('.swiper-button-prev.enabled').click(function(){
  
  // Disable swiper buttons so user doesnt click again
  $(".swiper-button").removeClass("enabled");
  
  // Set timeout for previous slide move
  setTimeout(function(){      
  
    // Move to previous slide
    swiper.slidePrev(); 
    
    // Re-enable swiper buttons
    $(".swiper-button").addClass("enabled");
    
    }, swiperDelay);

});


// Add event to next button
$('.swiper-button-next.enabled').click(function(){
   
  // Disable swiper buttons so user doesnt click again
  $(".swiper-button").removeClass("enabled");

  // Set timeout for next slide move
  setTimeout(function(){      
    
    // Move to next slide
    swiper.slideNext(); 
    
    // Re-enable swiper buttons
    $(".swiper-button").addClass("enabled");
    
    }, swiperDelay);

});
.swiper-container {
  width: 100%;
  height: 100%;
}
.swiper-slide {
  text-align: center;
  font-size: 18px;
  background: #fff;
  /* Center slide text vertically */
  display: -webkit-box;
  display: -ms-flexbox;
  display: -webkit-flex;
  display: flex;
  -webkit-box-pack: center;
  -ms-flex-pack: center;
  -webkit-justify-content: center;
  justify-content: center;
  -webkit-box-align: center;
  -ms-flex-align: center;
  -webkit-align-items: center;
  align-items: center;
}

.swiper-button {
  opacity: 0.4;
  transition: 0.3s all;
}
.swiper-button.enabled {
  opacity: 1;
}
