在幻灯片更改之前添加延迟

Question

我正在使用 Swiper Slider。有没有办法在我单击 next/prev 按钮后在幻灯片更改之前添加延迟？例如：我点击下一张按钮，等待 1 秒，然后切换到下一张幻灯片。我需要这个，因为我使用 CSS 制作了我自己的动画并且它需要 aprox。 1秒完成。

希望大家能帮帮我。

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;
    }

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="swiper-container">
      <div class="swiper-wrapper">
        <div class="swiper-slide">Slide 1</div>
        <div class="swiper-slide">Slide 2</div>
        <div class="swiper-slide">Slide 3</div>
        <div class="swiper-slide">Slide 4</div>
      </div>
      <!-- Add Arrows -->
      <div class="swiper-button-next"></div>
      <div class="swiper-button-prev"></div>
    </div>

Answer 1

这符合您的要求。

通过删除您的导航定义，我们可以为下一个和上一个按钮编写自己的操作。

我已经使用 setTimeout 等待指定的时间，然后再从您的库中触发内置的下一个/上一个函数。

我还添加了一些 CSS 以便在此期间按钮显示为禁用状态，以便用户了解他们应该再次单击。

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;
}
