vue展示数据怎么去掉时分秒？

怎么才能把passagelist里面的时间去掉时分秒，只展示年月日

<div
      v-for="(i, idx) in passageList"
      :key="idx"
      class="list_item flex justify-between align-center"
    >
      <span class="text-ellipsis">{{ i.title }}</span>

      <span class="date">{{ i.issueTime }}</span>

PolicyList() {
      // this.$myLoading.show()
      const { search } = this
      pageSysPolicyLibraryBySysCompany({
        companyFid: this.$store.getters.companys.companyFid,
        suFid: this.$store.getters.userFid,
        type: '0',
        types: ['0'],
        currentPage: search.currentPage,
        pageSize: search.pageSize
      }).then((res) => {
        if (res.code === '0') {
          this.passageList = res.data.list
          this.search.total = res.data.count
        }
        // this.$myLoading.close()
      })
    }

<span class="date">{{ i.issueTime.substring(0,10) }}</span>
