Question

这是我的代码片段。但没有响应返回到web页面。我在firebug中使用了调试，在jquery代码部分也没有调用成功/异常。请帮我解决这个问题。[没有发生任何错误。只是没有回复] 感谢

JSP

    function postMedicines() {
        var selectedMedicines = $('#sortable2').sortable('toArray').toString();
        var patientName=$('#patientName').val().toString();
        $.ajax({
            type : "POST",
            url : "setTabletsNames.htm",
            data : "selectedMedicines=" + selectedMedicines+"&patientName="+patientName,
            success : function(response) {
                alert('response : '+response);
                $('#info').html(response);
            },
            error : function(e) {
                alert('data : '+data);
                alert('Error: ' + e);
            }
        });
    }
</script>
</head>
<body>

<form action="" method="post">
Patient Name : <input type="text" name="patientName" id="patientName">

<br/><br/>
    <div style="font-weight: bold;">&nbsp;&nbsp;Available Medicines</div>
    <ul id="sortable1" class="droptrue">
    </ul>

    <div style="font-weight: bold;">Selected Medicines</div>
    <ul id="sortable2" class="dropfalse">
    </ul>

<button id="postButton" onclick="postMedicines()" >Post Data</button>
<div id="info" style="color: green;"></div>

</form>

控制器

@RequestMapping(value = "/setTabletsNames",method = RequestMethod.POST)
public @ResponseBody String setTabletsNames(@RequestParam("selectedMedicines") String []selectedMedicines,@RequestParam("patientName") String patientName) {
    Integer response=0;
    try {
        response= ePrescriberDAO.getTabletbyNameAndSave(patientName,selectedMedicines);
    } catch (Exception e) {
        e.printStackTrace();
    }
    if (response==1){
        return "success";
    }else{
        return "failure";
    }
}

控制器也调用了，但没有响应发送回JSP。在输入 patientName 之前，它的工作正常。有关jquery发送数据部分的任何问题。？

DAO

public Integer getTabletbyNameAndSave(String patientName,String []selectedMedicines) {
    int response=0;
    EPrescriber ePrescriber=new EPrescriber();
    List<SelectedTablets> selectedTabletsList=new ArrayList<SelectedTablets>();
    for (String item : selectedMedicines) {

        Tablets tablets=null;   
        String hql="from Tablets t where t.tradeName='"+item.trim()+"' ";
        Query queryList = sessionFactory.getCurrentSession().createQuery(hql);
        tablets=(Tablets)queryList.uniqueResult();

        SelectedTablets selectedTablets=new SelectedTablets();
        selectedTablets.setTablets(tablets);
        selectedTablets.setePrescriberid(ePrescriber);
        selectedTabletsList.add(selectedTablets);
        sessionFactory.getCurrentSession().save(selectedTablets);

    }

    ePrescriber.setPatientName(patientName);
    ePrescriber.setSelectedTablets(selectedTabletsList);
    sessionFactory.getCurrentSession().save(ePrescriber);
    response=1;
    return response;        
}

[Bico]                       |

这些代码需要拖放相关图标[可供选择]
