jQuery.ajax向后台传数组

如果html中checkbox选中多条记录向后台传值，js实现如下

var orderIds=[];
                var userCodes=[];
                $("input[name=‘cBox‘]:checked").each(function(){
//选中的checkbox记录，循环取出每条记录中orderId和userCode
                    var orderId=$(this).val();
                    var userCode=$(this).attr("userCode");
                    orderIds.push(orderId);
                    userCodes.push(userCode);
                });

                    $.ajax({
                        url:"batch.do",
                        data:"orderIds="+orderIds.join(",")+"&userCodes="+userCodes.join(","),
                        type:"post",
                        dataType:"text",
                        success: function(result){

                            alert(result);
                        }
                    });
                }

java后台接收数据

@RequestMapping(value="batch.do")
public String batch(HttpServletResponse response,HttpServletRequest request,HttpSession session){
        CustomerDBContextHolder.setDataSourceType(DataSourceInstances.WRITE_DATASOURCE);
        String orderIds = request.getParameter("orderIds");
        String[] orderId = orderIds.split(",");
        String userCodes = request.getParameter("userCodes");
        String[] userCode = userCodes.split(",");

html页面

<c:forEach items="${personList}" var="person" varStatus="n">
                        <tr class="<c:choose><c:when test="${n.index % 2==0 }">row-even</c:when><c:otherwise>row-odd</c:otherwise></c:choose>">
                            <td>
                            <input type="checkBox" name="cBox" userCode="${person.userCode"}/>
                            </td>
    <td>
                            <input id="orderId" name="orderId" value="${person.orderId}" type="hidden"/>
                                   </td>                        
</c:forEach>
