package main

import (
    "fmt"
    math"
)

func main() {
    //定义一个10的切片,假设这是10个数据记录
    var arr []int
    for i := 1; i <= 12; i++ {
        arr = append(arr,i)
    }

    分页展示
    var pagesize int = 10
    var start 1
    var stop int
    var pagecount 
    var curpage 总页数,向上取整,注意除之前要先转换类型为float64
    pagecount = int(math.Ceil(float64(len(arr)) / float64(pagesize)))
    for curpage = 1; curpage <= pagecount; curpage++ {
        if curpage ==  {
            start = 
        } else {
            start = (curpage-1)*pagesize + 
        }
        stop = curpage * pagesize
        if stop > len(arr) {
            stop = len(arr)
        }
        这里就可以查看开始和结束了
        fmt.Println(start,stop)
    }
