Vue 实现时间滑块

使用原生 HTML5 input range

通过 HTML5 的 input[type="range"] 结合 Vue 的数据绑定实现基础时间滑块：

<template>
  <div>
    <input 
      type="range" 
      min="0" 
      max="1440" 
      step="15" 
      v-model="minutes"
      @input="updateTime"
    >
    <p>当前时间: {{ formattedTime }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      minutes: 0
    }
  },
  computed: {
    formattedTime() {
      const hours = Math.floor(this.minutes / 60)
      const mins = this.minutes % 60
      return `${hours.toString().padStart(2, '0')}:${mins.toString().padStart(2, '0')}`
    }
  },
  methods: {
    updateTime() {
      console.log('Selected time:', this.formattedTime)
    }
  }
}
</script>

使用第三方组件库

Element UI 的滑块组件提供更丰富的功能：

<template>
  <el-slider
    v-model="minutes"
    :min="0"
    :max="1440"
    :step="15"
    :format-tooltip="formatTooltip"
    @change="handleChange"
  />
</template>

<script>
export default {
  data() {
    return {
      minutes: 0
    }
  },
  methods: {
    formatTooltip(val) {
      const hours = Math.floor(val / 60)
      const mins = val % 60
      return `${hours}:${mins < 10 ? '0' + mins : mins}`
    },
    handleChange(val) {
      console.log('时间变更:', this.formatTooltip(val))
    }
  }
}
</script>

自定义滑块组件

创建带有时间刻度的自定义滑块：

<template>
  <div class="time-slider">
    <div class="slider-track" ref="track" @click="handleTrackClick">
      <div 
        class="slider-thumb" 
        :style="{ left: thumbPosition + 'px' }"
        @mousedown="startDrag"
      ></div>
    </div>
    <div class="time-marks">
      <span v-for="hour in 24" :key="hour">{{ hour - 1 }}:00</span>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      currentTime: 0,
      isDragging: false
    }
  },
  computed: {
    thumbPosition() {
      return (this.currentTime / 1440) * this.$refs.track?.offsetWidth || 0
    }
  },
  methods: {
    startDrag(e) {
      this.isDragging = true
      document.addEventListener('mousemove', this.handleDrag)
      document.addEventListener('mouseup', this.stopDrag)
    },
    handleDrag(e) {
      if (!this.isDragging) return
      this.updateTimeFromPosition(e.clientX)
    },
    stopDrag() {
      this.isDragging = false
      document.removeEventListener('mousemove', this.handleDrag)
      document.removeEventListener('mouseup', this.stopDrag)
    },
    handleTrackClick(e) {
      this.updateTimeFromPosition(e.clientX)
    },
    updateTimeFromPosition(clientX) {
      const rect = this.$refs.track.getBoundingClientRect()
      const position = Math.min(Math.max(0, clientX - rect.left), rect.width)
      this.currentTime = Math.round((position / rect.width) * 1440)
      this.$emit('time-change', this.currentTime)
    }
  }
}
</script>

<style>
.time-slider {
  width: 100%;
  position: relative;
}
.slider-track {
  height: 4px;
  background: #ddd;
  position: relative;
  cursor: pointer;
}
.slider-thumb {
  width: 16px;
  height: 16px;
  background: #409eff;
  border-radius: 50%;
  position: absolute;
  top: -6px;
  transform: translateX(-50%);
  cursor: grab;
}
.time-marks {
  display: flex;
  justify-content: space-between;
  margin-top: 10px;
}
</style>

双向绑定时间范围

实现时间范围选择滑块：

<template>
  <div>
    <el-slider
      v-model="timeRange"
      range
      :min="0"
      :max="1440"
      :step="15"
      :format-tooltip="formatTooltip"
      @change="handleRangeChange"
    />
    <p>选择的时间范围: {{ formatTooltip(timeRange[0]) }} - {{ formatTooltip(timeRange[1]) }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      timeRange: [480, 1020] // 默认8:00-17:00
    }
  },
  methods: {
    formatTooltip(val) {
      const hours = Math.floor(val / 60)
      const mins = val % 60
      return `${hours}:${mins < 10 ? '0' + mins : mins}`
    },
    handleRangeChange(val) {
      console.log('时间范围变更:', val.map(this.formatTooltip))
    }
  }
}
</script>
