이번 플러그인은 pager 입니다.
http://www.j-dee.com/2008/12/22/jquery-pager-plugin/
이 pager의 각 단위는 span 으로 렌더링 됩니다. 그래서 디자인 하기가 편합니다..^^;;
그런데 이 pager는 페이징 방식이...다이얼방식(표현이 맞나 모르겠네요..@.@) 입니다.
즉 현재 활성화된 페이지가 가운데 오는 방식이죠...외국 사이트에서는 이러한 방식을 많이 쓰고 있습니다만..
우리의 고객들은....싫어 하더군요..ㅡ.ㅡ;
그래서 전통적인 방식의 기능도 추가 하였습니다.
사용법은 아래와 같습니다.
var initializePager = function(){
if(parseInt($('#totalCnt').val()) >= 0 ){
var cur = $.getUrlVars()['pageCnt'];
var rowCount = parseInt($('#rowCnt').val());
$('#pager').pager({
pagerType : 'classic',
pagenumber : rowCount==0?1:(cur==null?1:cur),
pagecount : rowCount==0?1:parseInt($('#totalCnt').val())%parseInt($('#rowCnt').val())==0?parseInt($('#totalCnt').val())/parseInt($('#rowCnt').val()):parseInt($('#totalCnt').val())/parseInt($('#rowCnt').val()) + 1,
buttonClickCallback: pagerCallback
});
}
};
// 페이저를 클릭 했을 경우
function pagerCallback(pageClickNumber){
var pageCnt = $.getUrlVars()['pageCnt'];
if(pageCnt == null){
if(location.href.indexOf('?') > 0 && $.getUrlVars().length > 0){
location.href = location.href+'&pageCnt='+pageClickNumber;
}else{
location.href = location.href+'?pageCnt='+pageClickNumber;
}
}
else{
var reg = /pageCnt=(\d+)/gi;
location.href = location.href.replace(reg, 'pageCnt='+pageClickNumber);
}
return false;
}
공통 js 파일에 위와 같이 선언해 놓고..
pager가 필요한 페이지에서만 위 함수를 콜하면 되겠습니다...
pager.js 의 전체 코드는 아래와 같습니다.
/*
* jQuery pager plugin
* Version 1.0 (12/22/2008)
* @requires jQuery v1.2.6 or later
*

*
* This version is far from perfect and doesn't manage it's own state, therefore contributions are more than welcome!
*
* Usage: .pager({ pagenumber: 1, pagecount: 15, buttonClickCallback: PagerClickTest });
*
* Where pagenumber is the visible page number
* pagecount is the total number of pages to display
* buttonClickCallback is the method to fire when a pager button is clicked.
*
* buttonClickCallback signiture is PagerClickTest = function(pageclickednumber)
* Where pageclickednumber is the number of the page clicked in the control.
*
* The included Pager.CSS file is a dependancy but can obviously tweaked to your wishes
* Tested in IE6 IE7 Firefox & Safari. Any browser strangeness, please report.
