基于uniapp vue3 的滑动抢单组件

通过在onMounted获取movable-area与movable-view实例，计算出可滑动的距离

效果图：

代码：

<template>
  <view class="slider-container">
    <movable-area class="movable-area" id="movableArea">
      <movable-view 
        class="slider-button"
        direction="horizontal"
        :x="sliderX"
        @change="onSliderChange"
        @touchend="onSliderEnd"
        id="movableView"
      >
        <text class="arrow-icon">»</text>
        <text>Slide to grab order</text>
      </movable-view>
    </movable-area>
  </view>
</template>

<script setup>
import { ref, onMounted } from "vue";

const sliderX = ref(0); // 滑块 X 轴位置
const maxX = ref(0);    // 最大可滑动距离

onMounted(() => {
  getMaxX(); // 组件加载后计算最大可滑动距离
});

const getMaxX = () => {
  uni.createSelectorQuery()
    .select("#movableArea")
    .boundingClientRect(areaRect => {
      uni.createSelectorQuery()
        .select("#movableView")
        .boundingClientRect(viewRect => {
          if (areaRect && viewRect) {
            maxX.value = areaRect.width - viewRect.width;
            console.log("动态计算 maxX:", maxX.value);
          }
        })
        .exec();
    })
    .exec();
};

const onSliderChange = (event) => {
  const x = event.detail.x;
  console.log("当前滑动位置:", x);

  if (x >= maxX.value) {
    console.log("滑到了最右边");
    onSliderEnd();
  }
};

const onSliderEnd = () => {
  console.log("滑动结束，执行逻辑...");
  sliderX.value = 0; // 可选择让滑块复位
};
</script>
