JS分页
1> JS分页,业务逻辑
(1) 分页采用的是一个叫jquery.pagination.js的一个jquery插件
(2) 需要jquery的支持,此项目中使用到的是jquery-2.1.1.min.js
(3) 分页需要的参数有:记录总数,每页显示个数,页码
(4) 添加搜索的条件,作为查询使用
2> 编写新的model,命名为data.go.其代码如下:
package models import ( "fmt" "github.com/astaxie/beego/orm" _ "github.com/go-sql-driver/mysql" ) // 用户 type User struct{ Id int64 `orm:"auto"` Name string `orm:"size(100)"` Nickname string `orm:"size(100)"` Pwd string `orm:"size(100)"` Email string `orm:"size(100)"` Sex string `orm:"size(2)"` Roleid string `orm:"size(100)"` Status int64 Phone string `orm:"size(16)"` } //根据用户数据总个数 func GetRecordNum(search string) int64 { o := orm.NewOrm() qs := o.QueryTable("user") if search !=""{ qs=qs.Filter("Name",search) } var us []User num, err := qs.All(&us) if err == nil { return num }else{ return 0 } } func SearchDataList(pagesize,pageno int,search string) (users []User) { o := orm.NewOrm() qs := o.QueryTable("user") if search !=""{ qs=qs.Filter("Name",search) } var us []User cnt, err := qs.Limit(pagesize, (pageno-1)*pagesize).All(&us) if err == nil { fmt.Println("count", cnt) } return us } //初始化模型 func init() { // 需要在init中注册定义的model orm.RegisterModel(new(User)) }
3> 控制器user.go,其代码如下:
package controllers import ( "secondweb/models" "fmt" "github.com/astaxie/beego" ) type UserController struct { beego.Controller } func (c *UserController) Get() { c.TplName = "list.html" } func (c *UserController) Post() { pageno,err:=c.GetInt("pageno") if err!=nil{ fmt.Println(err) } search:=c.GetString("search") userList:=models.SearchDataList(3,pageno,search) listnum:=models.GetRecordNum(search) c.Data["json"]=map[string]interface{}{"Count":listnum,"PageSize":3,"Page":pageno,"DataList":userList}; c.ServeJSON(); } type YonghuController struct { beego.Controller } func (c *YonghuController) Post() { pageno,err:=c.GetInt("pageno") if err!=nil{ fmt.Println(err) } search:=c.GetString("search") userList:=models.SearchDataList(3,pageno,search) listnum:=models.GetRecordNum(search) c.Data["json"]=map[string]interface{}{"Count":listnum,"PageSize":3,"Page":pageno,"DataList":userList}; c.ServeJSON(); }
4> 路由配置如下:
package routers import ( "secondweb/controllers" "github.com/astaxie/beego" ) func init() { beego.Router("/", &controllers.MainController{}) beego.Router("/Home/PageData", &controllers.UserController{}) beego.Router("/Home/PageNextData", &controllers.YonghuController{}) }
5> 新建一个list.html,其代码如下:
<!DOCTYPE html> <html> <head> <title>首页 - 用户列表页面</title> <link rel="shortcut icon" href="/static/img/favicon.png" /> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <style> .am-cf{ height: 50px; margin-top: 30px; line-height: 50px; text-align: center; vertical-align: middle; margin-left: 40%; } .am-fr{ float: left; line-height: 50px; text-align: center; vertical-align: middle; height: 50px; margin-top: -15px; } .am-pagination{ list-style:none; height: 50px; line-height: 50px; text-align: center; vertical-align: middle; } .am-pagination li{ float:left; margin-left: 10px; } .am-pagination li a{ text-decoration:none; } .am-jl{ float: left; margin-left: 20px; } .am-active{ color: #f00; } </style> </head> <body> <div class="row pull-right" style="margin-bottom: 20px;margin-right: 5px;text-align:right;margin-right: 40px;"> <input type="text" placeholder="请输入名称" id="txt_search"/> <button class="" onclick="search()">搜索</button> </div> <table class="table table-striped table-hover table-bordered "> <thead> <th style="text-align: center">ID</th> <th style="text-align: center">名称</th> <th style="text-align: center">昵称</th> <th style="text-align: center">密码</th> <th style="text-align: center">Email</th> <th style="text-align: center">性别</th> <th style="text-align: center">手机号</th> </thead> <tbody id="sortable"> </tbody> </table> <!--分页部分--> <div style="margin: 20px 0px 10px 0;"> <table style="margin: 0 auto;"> <tr> <td> <div id="pagination" class="pagination"></div> </td> </tr> </table> </div> <script type="text/javascript" src="/static/js/jquery-2.1.1.min.js"></script> <script type="text/javascript" src="/static/js/jquery.paginationNew.js"></script> <script type="text/javascript"> //页面的初始化 $(function () { //分页数据 InitData(); }) function search(){ var search = $("#txt_search").val();//名称 InitData(); } //使用分页插件pagination分页显示1 function InitData() { var search = $("#txt_search").val();//名称 $.ajax({ async: false, type: "post", url: "/Home/PageData", data: { search: search, pageno:0 }, success: function (data) { console.log('首页数据') console.log(data) var Count = data.Count var PageSize = data.PageSize; var Page =data.Page; $("#pagination").pagination(Count, { callback: pageselectCallback, num_edge_entries: 1, prev_text: "上一页", prev_show_always: true, next_text: "下一页", next_show_always: true, items_per_page: PageSize, current_page: Page, link_to: '#__aurl=!/Home/PageData', num_display_entries: 4 }); } }); } //使用分页插件分页后的回调函数2 function pageselectCallback(page_id, jq) { var search = $("#txt_search").val();//名称 $.ajax({ async: false, type: "post", url: "/Home/PageNextData", data: { search: search, pageno: (parseInt(page_id) + parseInt(1)), }, success: function (data) { console.log('下一页的数据') console.log(data) console.log(data.DataList) htmlData(data.DataList) } }); } function htmlData(data){ var html=''; for(var i=0;i<data.length;i++){ html+='<tr class="sort-item" id="module_'+data[i].Id+'" value="'+data[i].Id+'">'; html+=' <td style="text-align: center;width: 150px;"><span class="label label-default" >'+data[i].Id+'</span></td>'; html+=' <td style="text-align: center;width: 240px;" ><strong>'+data[i].Name+'</strong></td>'; html+=' <td style="text-align: center;width: 240px;" ><strong>'+data[i].Nickname+'</strong></td>'; html+=' <td style="text-align: center;width: 240px;" ><strong>'+data[i].Pwd+'</strong></td>'; html+=' <td style="text-align: center;width: 240px;" ><strong>'+data[i].Email+'</strong></td>'; html+=' <td style="text-align: center;width: 240px;" ><strong>'+data[i].Sex+'</strong></td>'; html+=' <td style="text-align: center;width: 240px;" ><strong>'+data[i].Phone+'</strong></td>'; html+='</tr>'; } $("#sortable").html(html); } </script> </body> </html>
6> Main.go的代码如下:
package main import ( "fmt" "github.com/astaxie/beego/orm" _ "secondweb/routers" "github.com/astaxie/beego" ) func init(){ dbhost := beego.AppConfig.String("dbhost") dbport := beego.AppConfig.String("dbport") dbuser := beego.AppConfig.String("dbuser") dbpassword := beego.AppConfig.String("dbpassword") db := beego.AppConfig.String("db") //注册mysql Driver orm.RegisterDriver("mysql", orm.DRMySQL) //构造conn连接 //用户名:密码@tcp(url地址)/数据库 conn := dbuser + ":" + dbpassword + "@tcp(" + dbhost + ":" + dbport + ")/" + db + "?charset=utf8" //注册数据库连接 orm.RegisterDataBase("default", "mysql", conn) fmt.Printf("数据库连接成功!%s\n", conn) } func main() { o := orm.NewOrm() o.Using("default") // 默认使用 default,你可以指定为其他数据库 beego.Run() }
7> App.conf配置文件如下:
appname = secondweb httpport = 9080 runmode = dev dbhost=192.168.1.87 dbport=3306 dbuser=root dbpassword=123456 db=test tablename=user
8> 运行起来的效果如下:
