dategrid 创造，重写分页

	$('#dg').datagrid({

			     frozenColumns:[[   //checkbox
            	{field:'ck',checkbox:true}   
       			 ]] 
			}); 
	//分页	
	   var p = $('#dg').datagrid('getPager');   
	    $(p).pagination({   
	        pageSize: 10,//每页显示的记录条数，默认为10   
	        pageList: [5,10,15],//可以设置每页记录条数的列表   
	        beforePageText: '第',//页数文本框前显示的汉字   
	        afterPageText: '页    共 {pages} 页',   
	        displayMsg: '当前显示 {from} - {to} 条记录   共 {total} 条记录'
