javascript - 我想与滑块一起滑动/移动猫头鹰点

Question

我想移动图像中显示的导航点与滑块一起移动，当单击每个栏时应该导航到相关的滑块。（更改活动类）我不希望它在横幅上保持静止。[![在此处输入图像描述][1]][1]

[1]：

我已经设法使用 html 移动导航点。

    $(function () {
        $('.owl-dot').on('click', function () {
            $(this).parent().find('.owl-dot.active').removeClass('active');
            $(this).addClass('active');
        });
    });

<div class="banner-slider-item1">
            <div class="owl-dots">
                <button role="button" class="owl-dot active"><span></span></button>

        </div><!-- banner-slider-item end -->

但是当我点击它们时它不会改变。任何人都可以帮忙吗？

我建议保留控件。但是，如果这是硬性要求，那么这里就是您如何维护控件的活动状态。我随机提取了一些样式，以便将简单的工作解决方案放在一起。我希望这有帮助。

$(function() {
  $('.owl-dot').on('click', function() {
    // dot element
    const $this = $(this);

    // take action only if the current slide is not active
    if (!$this.hasClass('active')) {

      // dot elment index
      const idx = $this.index();

      // slides container
      const $slideContainer = $this.closest('.slide-container');

      // set active state and remove that for other siblings
      $this.siblings().removeClass('active');
      $this.addClass('active');

      // get parent of slide to which we need to move
      const $targetSlide = $slideContainer.find('.banner-slider-item').eq(idx);

      // now set the active state in target slide
      $targetSlide.find('.owl-dot').removeClass('active');
      $targetSlide.find('.owl-dot').eq(idx).addClass('active');

      // finally move the slide
      $slideContainer.css({
        marginLeft: (-500 * idx) + 'px'
      });
    }
  });
});

.slide-window {
  display: flex;
  width: 500px;
  height: 300px;
  overflow: hidden;
}

.slide-container {
  position: relative;
  display: flex;
  transition: all 1s;
  transition-timing-function: ease;
}

.banner-slider-item {
  position: relative;
}

.owl-dot {
  cursor: pointer;
  width: 25px;
  height: 8px;
  border: 0;
  background-color: #ee4266;
}

.owl-dot:hover {
  background-color: #fff361;
}

.owl-dot.active {
  background-color: #FFD23F;
}

.banner-slider-item .container {
  position: absolute;
  top: 25%;
  height: 60%;
  right: 0;
  width: 70%;
  background-color: rgba(20, 20, 20, 0.6);
  color: #fff;
  padding: 15px 20px;
  font-family: Helvetica-Neue, Arial;
}

.banner-slider-item .container h1 {
  font-size: 1.6rem;
}
