controller中的使用

pno,_:=this.GetInt("page")//获取当前请求页
    var Items[]models.User
    conditions :=" order by id desc"
    var po pager.PageOptions
    po.ParamName = "page"
    po.TableName = "users"                                                 //指定分页的表名
    po.EnableFirstLastLink = true                                           //是否显示首页尾页 默认false
    po.EnablePreNexLink = true                                              //是否显示上一页下一页 默认为false
    po.Conditions = conditions                                              // 传递分页条件 默认全表
    po.Currentpage = int(pno)                                               //传递当前页数,默认为1
    po.PageSize = 20                                                     //页面大小  默认为20

    //返回分页信息,
    //第一个:为返回的当前页面数据集合,ResultSet类型
    //第二个:生成的分页链接
    //第三个:返回总记录数
    //第四个:返回总页数
    totalItem, totalPage, rs, pagerhtml2 := pager.GetPagerLinks(&po, this.Ctx)
    rs.QueryRows(&Items)      //把当前页面的数据序列化进一个切片内
    this.Data["pagerhtml"] = pagerhtml2
    this.Data["totalItem"] = totalItem
    this.Data["PageSize"] = po.PageSize
    this.Data["totalPage"] =totalPage
    this.Data["Items"] = Items
    this.TplName = "admin/user/user_list.tpl"

tpl中的使用

<div style="float:left;">{{.pagerhtml}}</div>
