A simple paging component written by myself, the main functions and implementations are all in JS. Only add a DIV to place the page to generate the paging and give the id of the container.
The html structure is as follows:
The code copy is as follows:
<ul id="pageDIV">
</ul>
class="pagination" gives the pagination style,
id="pageDIV" is used to place JS-generated pagination
The CSS structure is as follows:
The code copy is as follows:
.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: #cccccccc;
color: #ffffff;
}
The following is the JS structure, please refer to JQuery
The code copy is as follows:
/**
* @pageContentID Rendering the DIV element of the page
* @curPage Current start page
* @totalCount Total Number
* @pageRows Number of displays per page
* @callback The callback function that displays data
*/
function PageList(pageContentID, option){
this.pageContentID=document.getElementById(pageContentID);

$(function(){
var pager = new PageList("pageDIV",{
curPage:1,
TotalCount:26,
pageRows:1,
callback:callbackFuc
});
pager.init();
});
function callbackFuc(curpage){
}
illustrate:
This page is based on 10 pages. When it is lower than 10 pages, all pages are displayed. When it is greater than 10 pages, the page is turned to display the remaining pages.
Calling method:
The code copy is as follows:
$(function(){
var pager = new PageList("pageDIV",{
curPage:1,
TotalCount:26,
pageRows:1,
callback:callbackFuc
});
pager.init();
});
The above is the core code of this paging component. I hope you can like it.
