组件使用

<template>
  <view :style="customStyle">

  </view>
</template>

<script lang="ts" setup>
import Utils from "@/utils/Utils";
import {computed, onMounted, ref} from "vue";
import Log from "@/utils/Log";

interface NavbarStyle {
  statusBar: number;
  customBar: number;
}

const logger = new Log("顶部tab 自定义bar")

let navbar = ref<NavbarStyle>({
  statusBar: 0,
  customBar: 0,
})
//
const customStyle = computed(() => {
  return {
    // #ifdef MP-WEIXIN
    height: `${navbar.value.customBar + navbar.value.statusBar}rpx`,
    // #endif

    // #ifdef APP
    height: `${navbar.value.customBar}rpx`
    // #endif
  }
})
onMounted(() => {
  // navbar.value = getWXStatusHeight();
  Utils.getSysBar().then((res: any) => {
    navbar.value = res;
    logger.info(navbar.value, 'navbar');
  });
})
</script>
<style lang="scss" scoped>

</style>
