uni-app 微信 支付宝 小程序 使用 longpress 实现长按删除功能，非常简单 只需两步

1、先看效果

2、直接上代码 ui结构

<view class="bind" @longpress="deleteImage" :data-index="index">
      <view class="bind_left">绑定设备</view>
      <view class="bind_right">
        <view class="bind_top">
          <text class="bind_title">F039</text>
          <text>一拖四充电桩</text>
        </view>
        <view class="bind_body">
          <text class="bind_title">SN00000000000125 | 1F01</text>
          <image class="icon_imaeg1" src="../../static/saoma/back.png" mode="aspectFit"></image>
        </view>
        <view class="bind_bottom">
          <view class="bottom_title1">1</view>
          <view class="bottom_title1">2</view>
          <view class="bottom_title1">3</view>
        </view>
      </view>
    </view>

 3、js 逻辑

// 长按删除
const deleteImage = (e) => {
  console.log('长按', e);
  const index = e.currentTarget.dataset.index; //获取当前长按图片下标
  uni.showModal({
    title: '提示',
    content: '确定删除吗?',
    success: function (res) {
      if (res.confirm) {
        uni.showToast({
          title: '删除成功',
          icon: 'none'
        });
      } else if (res.cancel) {
        uni.showToast({
          title: '取消删除',
          icon: 'none'
        });
        console.log('用户点击取消');
      }
    }
  });
};
