方法一：

如果子组件使用跳转的方法

const navigateToRegion=()=>{
        uni.navigateTo({
            url: '/pagesD/components/selpow/selpow'
        });
        
    }

中/pagesD/components/selpow/selpow传递uni.$emit('selectedLabels', checkedKeys.value); 如何接收？

<script setup lang="ts">
import { ref, onMounted,onUnmounted } from 'vue';

const handleBack = () => {
  uni.navigateBack();
};

const navigateToRegion = () => {
  uni.navigateTo({
    url: '/pagesD/components/selpow/selpow'
  });
};

// 监听selectedLabels事件
const onSelectedLabels = (labels) => {
  console.log('Received labels:', labels);
};

onMounted(() => {
  // 监听全局事件
  uni.$on('selectedLabels', onSelectedLabels);
});

// 组件卸载时，移除事件监听
onUnmounted(() => {
  uni.$off('selectedLabels', onSelectedLabels);
});
</script>
