/**分页js插件
var ListPager = new listPaging();
先调用start方法加载上下文
然后调用dataLoad方法查询第一页数据
需要设置几个属性值
ListPager.property.pageSize = 4;
ListPager.start();
ListPager.property.prevControlID = "prevBtn";//上一页按钮id
ListPager.property.nextControlID = "nextBtn";//下一页按钮id
ListPager.property.controlActionType = "css";//操作类型attr为禁用 css为显示隐藏
然后在success这个成功回调的函数中设置上一页的状态
var id = ListPager.property.listItems.itemAt(0).get_id();
ListPager.property.PagingState = ["p_ID=" + id];
p_ID是必填项。否则无法返回上一页
如果查询的数据 需要排序需要在PagingState的数组中添加你的排序字段
例如：var title = ListPager.property.listItems.itemAt(0).get_item("Title");
ListPager.property.PagingState = ["p_ID=" + id,"p_Title="+title];
如果排序字段为时间类型，比如2013-01-01 请转成20130101
分页方法调用：ListPager.getListPager

经过很多次的测试，终于不再出bug。很好用的小插件。推荐各位博友。
