js对象实现数据分页效果

本文实例为大家分享了js对象实现数据分页效果的具体代码，供大家参考，具体内容如下
实现数据分页要清楚这个的方面的设计：
1.先模拟建立一个后台数据库，如下：

var peoson=[{"id":"1"," name":"鞠婧祎","sex":"女","age":"25","class":"八班","habby":"跳舞","score":"40","addess":"陕西西安长安区"},{"id":"2"," name":"关晓彤","sex":"女","age":"20","class":"八班","habby":"跳舞","score":"40","addess":"陕西西安长安区"},{"id":"3"," name":"赵丽颖","sex":"女","age":"26","class":"八班","habby":"跳舞","score":"40","addess":"陕西西安长安区"},{"id":"4"," name":"薛之谦","sex":"男","age":"37","class":"八班","habby":"跳舞","score":"40","addess":"陕西西安长安区"}]

2.设置每页的数据量，当前页数以及总页数
用函数动态设置总页数，根据总的数据量除以每页数据量来计算；
用函数动态设置每页里的数据是由总数据中的哪几条；
Allpage: function () {this.allpage = Math.ceil(this.Message.length / this.perpage); console.log(this.Message.length); console.log(this.allpage); },Nowpagenum:function(n){var first=(n-1)*this.perpage; //0var last=n*this.perpage ; //10this.nowpagenum =this.Message.slice(first,last); },

3.动态创建dom元素，给最大块添加子元素，用来存放每一条数据
Creatnews:function() {this.list.innerHTML = ""; for (var i = 0; i < this.perpage; i++) {var page_list = document.createElement("div"); page_list.className = "pagelist"; for (var key in this.nowpagenum[i]) {var per_child = document.createElement("div"); per_child.className = "perchild"; page_list.appendChild(per_child); per_child.innerHTML = this.nowpagenum[i][key]; //console.log(this.nowpagenum[i]); }this.list.appendChild(page_list); }},

4.创建列表下面的页数，进行前缩进，后缩进和前后缩进
假设总页数为
如果当前页数大于5页会进行前缩进，前面的页数从2到当前页数减一的页数缩进；
如果当前页数小于16时都会进行后缩进
介于两者之间的页数会进行前后缩进。
Page_ma:function(current,totle){var str=""; for(var i=1; i <=totle; i++){if(i==2 && current-3>i ){ //?????current>5i=current-1; str+="
  • ...
    • "; }else if(i==current+4 && current+4"+i+""; }else{str+="
  • "+i+"
    • "; }}}this .pageshu.innerHTML= str; },

    5.点击页数时，会跳转到当前页数的数据，并进行相应的缩进
    Pageclick:function(){var mini_list=document.getElementsByClassName ("minilist"); for(var k=0; k
    6.点击上下页，以及设置跳转的页数时，会跳转到当前页数的数据，并进行相应的缩进
    Clickevent:function(){Fenye. back.onclick =function(){Fenye.nowpage--; if(Fenye.nowpage<2){Fenye.nowpage=1; }Fenye.Page_ma(Fenye.nowpage,Fenye.allpage); Fenye.Pageclick(); Fenye.Creatnews (); Fenye.Nowpagenum (Fenye.nowpage); }; Fenye.go.onclick =function(){if(Fenye.nowpage>=Fenye.allpage){Fenye.nowpage=Fenye.allpage; }Fenye.nowpage++; Fenye.Page_ma(Fenye.nowpage,Fenye.allpage); Fenye.Pageclick(); Fenye.Creatnews (); Fenye.Nowpagenum (Fenye.nowpage); }; Fenye.tiao.onclick =function(){var put=document.getElementById ("in_put"); Fenye.nowpage = parseInt (put.value ) ; if(put.value>=Fenye.allpage){Fenye.nowpage = parseInt (put.value ); }Fenye.Page_ma(Fenye.nowpage,Fenye.allpage); Fenye.Pageclick(); Fenye.Creatnews (); Fenye.Nowpagenum (Fenye.nowpage); }}

    • 上一页
      • 下一页
      • 跳转到
      • 总页数:
