Question

我正在尝试制作滑块，但遇到了一个问题。我面临的问题是绝对项目会阻止滑块拖动事件。我需要某种方式来允许拖动基础图像以通过绝对定位的项目进行拖动。您知道如何实现这一目标吗？ 非常感谢！ Draggable =“ true”不是解决方案，因为此元素变为可拖动的（并且可以看到幻影拖动图像）。这是我的代码：如果愿意，可使用Codepen：https://codepen.io/saksija/pen/MWgqNeJ

HTML：

<div id="app">
  <div class="slider" ref="slider">
    <div class="slider-wrapper" ref="sliderContainer">
      <img ref="slide" src="https://image.shutterstock.com/image-photo/really-wide-panoramic-sunrise-shot-260nw-35170.jpg">
      <div v-for="id in 2" :class="['subitem', 'o-'+id]"></div>
    </div>
  </div>
</div>

Vue / Javascript：

var app = new Vue({
  el: '#app',
  data: () => ({
    startX: 0,
    lastTranslate: 0,
    translate: 0
  }),
  watch: {
    translate(value) {
      this.$refs.sliderContainer.style.transform = `translate3d(${value}px, 0px, 0px)`;
    }
  },
  methods: {
    dragStart(event) {
      this.startX = event.screenX;
    },
    dragEnd(event) {
      this.translate = this.lastTranslate;
    },
    dragMove(event) {
      if (event.screenX === 0) return;

      let distance = event.screenX - this.startX;
      let newTranslate = this.translate + distance;
      let sliderContainer = this.$refs.sliderContainer;

      this.lastTranslate = newTranslate;
      sliderContainer.style.transform = `translate3d(${newTranslate}px, 0px, 0px)`;
    },
  },
  mounted() {
    let slider = this.$refs.slider;
    slider.addEventListener('dragstart', this.dragStart);
    slider.addEventListener('drag', this.dragMove);
    slider.addEventListener('dragend', this.dragEnd);
  }
})

CSS：

#app {
  position: relative;
  width: 100vw;
  height: 100vh;
  overflow: hidden;
}
.slider {
  position: relative;
  display: flex;
  width: 100%;
  height: 100%;
}
.slider-wrapper {
  position: relative;
  display: block;
  height: 100%;
}
.slider img {
  position: relative;
  display: block;
  height: 100%;
}
.subitem {
  position: absolute;
  top: 20%;
  bottom: 20%;
  width: 100px;
  background-color: red;
  user-select: none;
}
.subitem.o-1 {
  left: 3%;
}
.subitem.o-2 {
  left: 20%;
}

Answer 1

假设不需要与.subitem进行交互，则可以在它们上使用pointer-events:none;。例如：

.subitem {
  position: absolute;
  top: 20%;
  bottom: 20%;
  width: 100px;
  background-color: red;
  user-select: none;
  pointer-events:none;
}
