一、删除最后一条数据跳转到上一页

/*
paginationOptions: {
    currentPage: 1,
    pageSize: 10,
    total: 0,
},
*/
async function removeDone() {
  this.wrapperLoading = true
  const { name, uuid } = this.currentRow
  const { success } = await removeAccount({ uuid })
  this.wrapperLoading = false
  if (success) {
    this.$notify({
      type: 'success',
      message: `账号${name}删除成功`,
    })
    // 方案一: 判断是否为最后一条数据 并且总数据不能小于1
    const { total, currentPage } = this.paginationOptions.currentPage
    if (this.contactsData.length === 1 && total > 1) {
      this.paginationOptions.currentPage = currentPage - 1
    }

    // 方案二:
    /*  let { currentPage,pageSize,total} = this.paginationOptions
          //求删除后还有几页
          let deleteAfterPage = Math.ceil((total - 1) / pageSize)
          //若删除后页数小于当前页, 取删除后的页数;否则不变
          let curPage = currentPage > deleteAfterPage ? deleteAfterPage : currentPage
          //当前页只有一页则为1,否则取计算得到的页
          this.paginationOptions.currentPage = curPage < 2 ? 1 : curPage */

    this.queryAccount()
  }
  else {
    this.$notify({
      type: 'error',
      message: `账号${name}删除失败`,
    })
  }
}
