//注：LO是表格的id； 需要自己创建表头， n行，9列的表格；
var tab_id;
function varify(cardinno) {
tab_id=document.getElementById("Layer1");
displayp();
tab_id.style.display="none";
var url="getRefInfoServlet?cardInNo="+cardinno;
var myAjax=new Ajax.Request(url,{method:'post', parameters:'0', onSuccess:doOnComplete, asynchronous:true});
}
var doOnComplete=function(xml_httpRequest){
var msg=eval(xml_httpRequest.responseText);
var info=msg.length;
var row;
var col;
if(info>0)
{
for(var i=0;i
Java background storage json object: 
/**
* 根据卡内码得到最近的租还车记录
* 返回json对象
* @param cardInNo
* @return
*/
public String getRefInfo(String cardInNo)
{
StringBuffer bf=new StringBuffer(1024);
bf.append("");//sql语句
System.out.println(bf.toString());
/************ 存储json对象***************/
List jsonList=new ArrayList();
    try {
    /****************获得判断信息存入数组中*******************/
    String [][] str=getArrayByName(bf.toString());
    if(str!=null){
    for (int i = 0; i < str[0].length; i++) {
    JSONObject returnValue =new JSONObject();
    returnValue.put("a", str[0][i])
    .put("b", str[1][i])
    .put("c", str[2][i].trim().equals("")?"":str[2][i].substring(0, 19))
    .put("d", str[3][i].trim().equals("")?"":str[3][i].substring(0, 19))
    .put("e", str[4][i])
    .put("f", str[5][i])
    .put("g", str[6][i])
    .put("h", str[7][i])
    .put("i", str[8][i]);
    jsonList.add(returnValue);
    }
  }
}catch (Exception e) {
e.printStackTrace();
}
System.out.println(jsonList.toString());
return jsonList.toString();
}
