怎么把javascript转换成jquery？？？

function Page(iAbsolute,sTableId,sTBodyId)
{
this.absolute = iAbsolute; //每页最大记录数
this.tableId = sTableId;
this.tBodyId = sTBodyId;
this.rowCount = 0;//记录数
this.pageCount = 0;//页数
this.pageIndex = 0;//页索引
this.__oTable__ = null;//表格引用
this.__oTBody__ = null;//要分页内容
this.__dataRows__ = 0;//记录行引用
this.__oldTBody__ = null;
this.__init__(); //初始化;
};
/*
初始化
*/
Page.prototype.__init__ = function(){
this.__oTable__ = document.getElementById(this.tableId);//获取table引用
this.__oTBody__ = this.__oTable__.tBodies[this.tBodyId];//获取tBody引用
this.__dataRows__ = this.__oTBody__.rows;
this.rowCount = this.__dataRows__.length;
try{
this.absolute = (this.absolute <= 0) || (this.absolute>this.rowCount) ? this.rowCount : this.absolute;
        this.pageCount = parseInt(this.rowCount%this.absolute == 0
? this.rowCount/this.absolute : this.rowCount/this.absolute+1);
}catch(exception){}
this.__updateTableRows__();
};
Page.prototype.GetBar=function(obj)
{
var bar= document.getElementById(obj.id);
bar.innerHTML= "每页"+this.absolute+"条/共"+this.rowCount+"条";// 第2页/共6页 首页 上一页 1 2 3 4 5 6 下一页 末页 
}
