jquery扩展的分页对象
/*
jquery 分页函数
注意此函数,只生成前端的相关分页连接,服务器端的数据处理。请自行编写。
使用示例:
var p = $.page({url:'aaa.php?kkk=88',count:80,page:1,pagesize:6});
console.log(p.getPageList(4));
*/
jQuery.extend({
page:function(p){
var _self = this;
var url;
var count = parseInt(p.count);
var page = parseInt(p.page);
var pagesize = parseInt(p.pagesize);
if(p.url ){
url = p.url;
}else{
url = location.href;
var re = /[?|&]page=\d*/g;
url = url.replace(re, "");
}
if( !(page>1) ){
page = 1;
}
var pageCount = ( count % pagesize > 0 ? parseInt(count / pagesize + 1) : parseInt(count / pagesize) );
var delimiter = '?';
function p_delimiter(url){
if(url.search("\\?")<0){
return '?page=';
}else{
return '&page=';
}
}
delimiter = p_delimiter(url);
