自己写的一个简单的分页组件,主要功能还有实现都在JS中,html页面中只用增加一个放置生成分页的DIV,并给定容器的id.
html结构如下:
<ul class="pagination" id="pageDIV">
</ul>
class="pagination" 给定了分页的样式,
id="pageDIV"用于放置JS生成的分页
CSS结构如下:
.pagination{
margin-top: 10px;
margin-bottom: 10px;
display: inline-block;
padding-left: 0;
margin: 20px 0;
border-radius: 4px;
}
.pagination>li {
display: inline;
}
.pagination>li:first-child>a{
margin-left: 0;
border-top-left-radius: 4px;
border-bottom-left-radius: 4px;
}
.pagination>li>a{
position: relative;
float: left;
padding: 6px 12px;
margin-left: -1px;
line-height: 1.42857143;
color: #337ab7;
text-decoration: none;
background-color: #fff;
border: 1px solid #ddd;
cursor: pointer;
}
.pagination>li>a.navcur{
background: #cccccc;
color: #ffffff;
}
下面是JS结构,注意要引用JQuery
/**
* @pageContentID 渲染分页的DIV元素
* @curPage 当前开始页
* @totalCount 总数量
* @pageRows 每页显示数量
* @callback 显示数据的回调函数
*/
function PageList(pageContentID,option){
this.pageContentID=document.getElementById(pageContentID);
this.curPage=option.curPage;
this.totalCount=option.totalCount;
this.pageRows=option.pageRows;
this.callback=option.callback;
this.pageSize=Math.ceil(this.totalCount/this.pageRows);
}
PageList.prototype={
init:function(){
this.renderbtn();
},
firstpage:function(){

_self._numA=document.createElement("a");
_self._numA.innerHTML=i;
_self._num.appendChild(_self._numA);
this.pageContentID.appendChild(_self._num);
_self._num.onclick= function () {
var curpage = $(this).text();
_self.gotopage(curpage);
}
}
}
else{
if(_self.curPage<=10){
for(var i= 1;i<=10;i++){
_self._num=document.createElement("li");
_self._numA=document.createElement("a");
_self._numA.innerHTML=i;

$(".pagination li").each(function(){

},
renderbtn: function () {
$(".pagination").html("");
this.firstpage();
this.prewpage();
this.pagenum();
this.nextpage();
this.lastpage();
}
};
$(function(){
var pager = new PageList("pageDIV",{
curPage:1,
totalCount:26,
pageRows:1,
callback:callbackFuc
});
pager.init();
});
function callbackFuc(curpage){
}
说明:
此分页是以10页为标准,低于10页的时候全部显示,大于10页的时候,进行翻页显示余下页数.
调用方法:
$(function(){
var pager = new PageList("pageDIV",{
curPage:1,
totalCount:26,
pageRows:1,
callback:callbackFuc
});
pager.init();
});
以上就是本分页组件的核心代码了，希望小伙伴们能够喜欢。
