分页1 - 前端 ol.pager

1.js-api:

ol.loader.mods["ol.pager"] = [
	"jquery",
	{uri: "../ol.pager/pager.js",type:"js",	charset: "utf-8",depend:true},
	{uri: "../ol.pager/pager.css",type:"css",	charset: "utf-8"}
];

2.pager.js

必须传入的参数：

1.pageNumber

2.pageCount

3.totalRecord

4.pageSize

由pageNumber+pageSize能算出RS的移向
